METHODS OF USING SHAPE MEMORY ALLOYS FOR
BUTTRESS ATTACHMENT
CROSS REFERENCE TO RELATED APPLICATIONS
This applicatioil claims priority from and the benefits of United States provisional application No. 60/854,821 filed on October 26, 2006, the entire contents of which are incorporated herein by reference.
BACKGROUND
Techniccil Field The present disclosure relates to surgical instruments, devices and methods of using the saine and, more particularly, surgical instruments including surgical stapling devices for applying buttress attachments, buttress attachments and methods of using and applying the same.
Discussion of Related Art In some surgical operations, surgical supports or buttresses, e.g., meshes, are employed by surgeons to bridge, repair and/or reinforce tissue defects within a patient, especially those occurring in the abdominal wall, chest wall, diaphragm and other musculo-aponeui=otic areas of the body. Surgical supports are disclosed in, e.g., U.S. Pat.
.Nos. 3,054,406, 3,124,136, 4,347,847, 4,655,221, 4,838,884 and 5,002,551.
During such operatioiis, surgeons employ conventional or known suturing or anchoring techniques to apply such supports to body tissue. For example, U.S. Pat. Nos. 4,452,245 and 5,203,864 describe methods for suturing or anchoring mesh supports to body tissue, especially during hernia repair operations.
Surgical instruments including surgical stapling devices are employed by surgeons to sequentially or simultaneously apply one or more rows of surgical fasteners, e.g., staples or two-part fasteners, to body tissue for the purpose of joining segments of body tissue together. Such devices generally consist of a pair of jaws or finger-like structures between which body tissue to be joined is placed. When the instrument is actuated, or "fired," longitudinally moving firing bars contact staple drive members in one of the jaws, thereby pushing surgical staples through the body tissue and into an anvil in the opposite jaw which criinps the staples closed. If tissue is to be removed, a knife blade can be provided to cut between lines of staples. Examples of such instruments are described in U.S. Pat. Nos. 4,354,628, 5,014,899 and 5,040,715, each of which are incorporated herein by reference.
Surgical stapling devices have found widespread application in surgical operations where body tissue must be joined or removed. When operating on thin tissue, such as thin emphysematous lung tissue, it is important to effectively seal the tissue which can be particularly prone to air leakage. Preventing or reducing air leakage can significantly decrease post operative recovery time. Thus, it is advantageous to provide surgical buttresses for use with surgical stapling devices which enhance sealing at the surgical site.

DETAILED DESCRIPTION OF EMBODIMENTS
Preferred embodiments of the presently disclosed surgical stapling devices will now be described in detail with reference to the drawiilg figures wherein like reference numerals identify siinilar or identical elements. As used herein aild as is traditional, the term "distal" will refer to that portion which is further from the user while the term "proximal" will refer to that portion which is closer to the user.
A surgical stapling device, in accordance with an embodiment of the present disclosure, is shown generally as 100 in FIGS. 1-7. Surgical stapling device 100 includes a cartridge receiving half-section 112, an anvil half-section 114 operatively couplable or connectable to cartridge receiving half-section 112, a cartridge assembly 116 configured and adapted to be removably mounted within a distal end of cartridge receiving half-section 112 and a firing slide 120 configured and adapted to be slidably received within cartridge receiving half-section 112.
As seen in FIG. 1, anvil half-section 114 is provided with an anvil plate 144 configured and dimensioned to be fit over a distal end of anvil half-section 114. Anvil plate 144 includes a plurality of anvil pockets formed therein (not shown), arranged in two pairs of longitudinal rows, and an anvil knife track (not shown) formed longitudinally therealong.
Reference may be made to U.S. Patent Application Serial No. 10/508,191, filed September 17, 2004, the entire content of which is incorporated herein by reference, for a more detailed discussion of the structure and operation of surgical stapling device 100.
As seen in FIGS. 1-3, surgical stapling device 100 includes a buttress attachment feature 160 operatively associated with at least one of the distal end of cartridge receiving half-section 112, distal end of anvil half-section 114, cartridge assembly 116 and anvil plate 144. Each buttress attachment feature 160 includes a plurality of fingers 162 positioned along a length of at least one of the distal end of cartridge receiving half-section 112, distal end of anvil half-section 114, cartridge assembly 116 and anvil plate 144. In an embodiment, fingers 162 may be placed along a length of a knife channel "K"
fonned in cartridge assembly 116 and/or anvil plate 144 (not shown).
In one embodiment, fingers 162 are spaced apart from one another. Fingers 162 function to releasably and/or selectively secure a surgical buttress "B" to a tissue contacting surface "T" of any of the distal end of cartridge receiving half-section 112, distal end of anvil half-section 114, cartridge assembly 116 and anvil plate 144. In one embodiinent, as seen in FIGS. 1-3, fingers 162 may be supported on and/or extend from a backspan or crown 164. Backspan 164 may be secured to both side surfaces of distal end of cartridge receiving lialf-section 112 and/or both side surfaces of distal end of anvil half-section 114.
Fingers 162 have a first position in which fingers 162 extend substantially orthogonally from a tissue contacting surface "T" of any of the distal end of cartridge receiving half-section 112, distal end of anvil half-section 114, cartridge assembly 116 and anvil plate 144. In the first position, fingers 162 are oriented so as to enable and/or allow placement and/or removal of surgical buttress "B" into or out of contact with tissue contacting surfaces "T".
Fingers 162 have a second position in which at least a distal or free end of fingers 162 extend substantially parallel to tissue contacting surface "T" of any of the distal end of cartridge receiving half-section 112, distal end of anvil half-section 114, cartridge assembly 116 and anvil plate 144, in a direction towards staple pockets "P" or anvil pockets (not shown). The anvil pockets are formed in the surface of anvil plate 144 and are in juxtaposed relation to staple pockets "P". In the second position and with a surgical buttress "B" in position against tissue contacting surface "T" of any of the distal end of carti-idge receiving half-sectioii 112, distal end of anvil half-section 114, cartridge assembly 116 and anvil plate 144, fingers 162 are oriented so as to prevent movement and/or removal of surgical buttress "B" relative to and/or from tissue contacting surfaces "T" of any of the distal end of cartridge receiving half-section 112, distal end of anvil half-section 114, cartridge assembly 116 and anvil plate 144.
At least fingers 162 of buttress attachment feature 160 is fabricated fronl a shape memory alloy (i.e., Nickel Titanium, NiTi, Nitinol, etc.), a shape memory polymer, or any other suitable material exhibiting shape memory properties during elevated temperatures. Shape memory alloys, such as NiTi, undergo a phase transformation (i.e., austenite to martensite and vise versa) during temperature fluctuations (i.e., increases and decreases).
In use, as seen in FIGS. 1 and 2, with buttress attachinent features 160 at a first temperature, fingers 162 are oriented in the first position, as described above. With fingers 162 in the first position, a surgical buttress "B" inay be placed in position against tissue contacting surfaces "T" of anvil plate 144 aiid/or cartridge assembly 116. With surgical buttress "B" so positioned, the temperature in the proximity of the distal ends of cartridge receiving half-section 112 and/or anvil half-section 114 is varied from the first temperature to a second temperature, i.e., either elevated or reduced relative to the first temperature. At the second temperature, buttress attachment features 160 undergo a phase transformation, as described above, wherein free ends of fingers 162 move to the second position, as described above, to secure, maintain, retain or otherwise hold surgical buttress "B" in contact and in position on tissue contacting surface "T" of cartridge half-section 112 and/or anvil half-section 114.
In one embodiment, surgical buttress "B" is configured aiid sized such that fingers 162 of buttress attachment features 160 are disposed along outer edges thereof, when in the first position, and the distal ends of fingers 162 deflect down atop a tissue contact surface of surgical buttress "B" when in the second position. In another embodiment, fingers 162 of buttress attachment features 160, when in the first position, may extend substantially orthogonally from tissue contacting surfaces "T" of cartridge assembly 116 and/or anvil plate 144 at a location disposed between a side edge thereof and knife channel "K". In this embodiment, surgical buttress "B" is positioned against tissue contacting surfaces "T" of cartridge assembly 116 and/or anvil plate 144 such that fingers 162 penetrate therethrough (not shown). Moreover, in this embodiment, when the distal ends of fingers 162 are in the second position, the distal ends of fingers 162 may extend toward and/or away from knife channel "K".
In another einbodiment, fingers 162 of buttress attachment features 160, as described above, may be positioned along a length of knife channel "K". In this embodiment, surgical buttress "B" is positioned against tissue contacting surfaces "T" of cartridge assembly 116 and/or anvil plate 144 such that fingers 162 penetrate therethrough (not shown). Moreover, in this embodiment, when the distal ends of fingers 162 are in the second position, the distal ends of fingers 162 may extend away from knife channel "K".
With surgical buttress "B" so positioned, the distal end of surgical stapling device 100 may be positioned at the target surgical site with surgical buttress "B"
securely held in position against tissue contacting surfaces "T" of cartridge assembly 116 and/or anvil plate 144. Surgical buttress "B" is properly positioned when at least a substantial portion of staple pockets "P" is covered thereby.
Buttress attachment features 160 may be positioned on cartridge receiving half-section 112 and/or anvil half-section 114 in such a manner so as to not increase an outer circumferential profile of the distal ends thereof. In this manner, buttress attachment features 160 do not interfere with the placement of the distal end of surgical stapling device 100 at the target surgical site. For example, with buttress attachment features 160 positioned along knife channel "K" (as shown in phantom in FIGS. 2 and 3), buttress attachment features 160 do not, at any time, extend beyond an outer profile of distal ends of cartridge receiving half-section 112 arid/or anvil half-section 114.
Turning now to FIGS. 4 and 4A, a buttress attachment feature, according to another embodiment of the present disclosure, is generally designated as 160a.
As shown in FIGS. 4 and 4A, a pair of buttress attachment features 160a extend from opposed sides of distal ends of cartridge receiving half-section 112 and/or anvil half-section 114, however, it is contemplated that in an embodiment, buttress attachment features 160a inay extend from knife channel "K" (see FIGS. 5 and 5A).
Each buttress attachment feature 160a includes a plurality of ribs 162a each having a first end positioned on sides of distal ends of cartridge receiving half-section 112 and/or anvil half-section 114 at a location proximate a mid-point thereof, and a second end extending away from sides of distal ends of cartridge receiving half-section 112 and/or anvil half-section 114 and extending along an entire length of the distal ends of cartridge receiving half-section 112 and/or anvil half-section 114, thereby defining a fan-like configuration. Each buttress attachment feature 160a further includes a panel 166a of suitable biocompatible mesh-like material disposed over ribs 162a.
While separate surgical buttresses "B" are shown positioned over staple pockets "P", it is envisioned and contemplated that panels 166a of buttress attachment features 160a may function as the surgical buttresses "B".
As seen in FIG. 4, buttress attachment features 160a have a first position in which ribs 162a and panels 166a are oriented substantially orthogonal relative to tissue contacting surfaces "T" of cartridge assembly 116 and/or anvil plate (not shown). In this orientation, surgical buttresses "B" may be positioned at least partially over staple pockets "P".
As seen in FIG. 4A, buttress attachinent features 160a have a second position in which ri.bs 162a and panels 166a are oriented substantially parallel relative to tissue contacting surfaces "T" of cartridge assembly 116 and/or anvil plate (not shown). In this orientation, ribs 162a and panels 166a function to maintain surgical buttresses "B" in position against tissue contacting surfaces "T" of cartridge assembly 116 and/or anvil plate (not shown).
Altei-natively, if panels 166a are to function as surgical buttresses "B", positioning of ribs 162a and panels 166a to the second position results in placement of the surgical buttress into position against tissue contacting surfaces "T" of cartridge assembly 116 and/or anvil plate (not shown).
In the present embodiment, ribs 162a may be fabricated from suitable shape meinory materials in a manner similar to fingers 162 disclosed above. In this manner, buttress attachmeilt features 160a may be oriented from the first to the second position, as needed, with a change in the temperature thereof.
Turning now to FIGS. 6 and 6A, a buttress attachment feature, according to another embodiinent of the present disclosure, is generally designated as 160b. As shown in FIGS. 6 and 6A, a pair of buttress attachment features 160b extend from opposed sides of distal ends of cartridge receiving half-section 112 and/or anvil half-section 114, however, it is contemplated that in an embodiment, buttress attachmcnt fcatures 160b may extend from knife channel "K" (not shown).
Each buttress attachment feature 160b includes a frame 162b having legs 168b which extend from opposed sides of distal ends of cartridge receiving half-section 112 and/or anvil half-section 114, at a location proximate a mid-point thereof, and a drape 166b supported on and extending over frame 162b. Drape 166b may be fabricated from a suitable biocompatible mesh-like material. In this manner, drape 166b may take the place of surgical buttress "B". However, if desired, a separate surgical buttress "B" may be used in conjunction with buttress attachment feature 160b.
As seen in FIG. 6, buttress attachment features 160b have a first position in which frame 162b and drapes 166b are oriented substantially orthogonal relative to tissue contacting surfaces "T" of cartridge asseinbly 116 and/or anvil plate (not shown). In this orientation, drapes 166b do not overlie staple pockets "P". Also, in this orientation, separate surgical butti-esses (not shown) may, if being used, be positioned at least partially over staple pockets "P".
As seen in FIG. 6A, buttress attachment features 160b have a second position in which frame 162b and drapes 166b are oriented substantially parallel relative to tissue contacting surfaces "T" of cartridge assembly 116 and/or anvil plate (not shown). In this orientation, drapes 166b overlie staple pockets "P" and may act as a surgical buttress.
Also, in the present orientation, if a separate surgical buttress (not shown) has been positioned over staple pockets "P" of cartridge assembly 116 and/or anvil plate, frame 162b and drapes 166b function to maintain the separate surgical buttress in position against tissue contacting surfaces "T" of cartridge assembly 116 and/or anvil plate (not shown).
In the present embodiment, frames 162b may be fabricated from suitable shape memory materials in a manner similar to fingers 162 disclosed above. In this manner, buttress attachment features 160b may be oriented from the first to the second position, as needed, with a change in the temperature thereof.
It is contemplated that legs 168b of each buttress attachment feature 160b may extend froin knife channel "K", at a location proximate a mid-point thereof.

Cartridge assembly 222 houses a plurality of staples (not shown). Anvil assembly 224 is movable in relation to cartridge assembly 222 between an open position spaced from cartridge assembly and aii approximated or clamped position in juxtaposed alignment with cartridge assembly 222.
Handle assembly 212 includes a stationary handle mcmbcr 226, a movable handle or trigger 228 and a barrel portion 230. A rotatable member 232 is rotatably mounted to the forward end of barrel portion 230 and secured to elongated body 214 to facilitate rotation of elongated body 214 in relation to handle assembly 212. An articulation lever 230a is supported on a distal portion of barrel portion 230 and is operable to effect articulation of tool assenlbly 220 with respect to body portion 218 of DLU
216. A pair of return knobs 236 are inovably supported along barrel portion 230 to effect movement of surgical stapling device 200 from an advanced position to a retracted position.
Reference may be made to U.S. Patent Application Serial No. 10/490,790, filed October 4, 2002, the entire content of which is incorporated herein by reference, for a inore detailed discussion of the structure and operation of surgical stapling device 200.
l0 As seen in FIGS. 7-10, surgical stapling device 200 includes a buttress attachment feature 260 operatively associated with at least one of the distal end of cartridge assembly 222 and anvil assembly 224. Each buttress attachment feature 260 may include any of the buttress attachment features 160, 160a or 160b described above in regards to surgical stapling device 100 and shown in FIGS. 1-6A. Accordingly, in the interest of clarity and brevity, buttress attachment feature 260 of FIGS. 7-10 is shown and described substantially as buttress attachment feature 160 above.
As best seen in FIG. 8, each buttress attachment feature 260 includes a plurality of fingers 262 exteilding from a backspan 264 which backspan 264 is positioned opposed sides of at least one of the distal end of cartridge assembly 222 and anvil assembly 224, however, it is contemplated that in an embodiment, buttress attachment features 260 may extend from kiiife channel "K" (see FIG. 9).
Fingers 262 have a first. position in which fingers 262 extend substantially orthogonal relative to tissue contacting surface "T" of cartridge assembly 222 and/or anvil assembly 224. While in the first position, fingers 262 are oriented so as to enable and/or allow placement anci/or removal of surgical buttress "B" into or out of contact with tissue contacting surfaces "T".
Fingers 262 have a second position in which at least a distal or free end of fingers 262 extend substantially parallel to tissue contacting surface "T" of cartridge assembly 222 and/or anvil assembly 224, in a direction towards staple pockets "P" (see FIG. 10) or anvil pockets "P" (see FIG. 9). While in the second position and when a surgical buttress "B" is in position against tissue contacting surface "T" of cartridge assembly 222 and/or anvil assembly 224, fingers 262 are oriented so as to prevent movement and/or removal of surgical buttress "B" relative to and/or from tissue contacting surfaces "T" of cartridge asseinbly 222 and/or anvil assembly 224.
At least fingers 262 of buttress attachment feature 260 is fabricated from a shape memory alloy (i.e., Nickel Titanium, NiTi, Nitinol, etc.), a shape memory polymer, or any other suitable material exhibiting shape memory properties during elevated temperatures.
Use of buttress attachment feature 260 is substantially similar to use of buttress attachment feature 160 and thus, in the interest of brevity, will not be described in extensive detail hereinbelow.
In use, with buttress attacliment features 260 at a first temperature, fingers 262 are oriented in the first position, as described above. With fingers 262 in the first position, a surgical buttress "B" may be placed in position against tissue contacting surfaces "T" by placing surgical buttress "B" between fingers 262, as seen in FIG. 8, or by penetrating fingers 262 through surgical buttress "B", as seen in FIGS. 9 and 10. With surgical buttress "B" so positioned, the temperature in the proximity of cartridge assembly 222 and anvil assembly 224 is varied from the first temperature to a second temperature, i.e., either elevated or reduced relative to the first temperature. At the second temperature, buttress attachmeilt features 260 undergo a phase transformation, as described above, wherein free ends of fingers 262 move to the second position, as described above, to secure, tnaintain, retain or otherwise hold surgical buttress "B" in contact and in position on tissue contacting surface "T" of cartridge assembly 222 and anvil assembly 224.
As seen in FIGS. 8-10, free ends of fingers 262 are shown in a first position near a proximal end of cartridge assembly 222 and anvil assembly 224 and in a second position near a distal end of cartridge assembly 222 and anvil assembly 224. As seen in FIG. 8, when the distal ends of fingers.262 are in the second position, the distal ends of fingers 262 extend toward knife channel "K" and across a width of surgical buttress ``B". As seen in FIGS. 9 and 10, when the distal ends of fingers 262 are in the second position, the distal ends of fingers 262 extend away from knife channel "K" and across a width of surgical buttress "B".
With surgical buttress "B" so positioned, the distal end of surgical stapling device 200 may be positioned at the target surgical site with surgical buttress "B"
securely held in position against tissue contacting surfaces "T" of cartridge assembly 222 and/or anvil assembly 224. The distal end of surgical stapling device 200 may be introduced to the target surgical site through a trocar, cannula, port or the like.
Buttress attachment features 260 may be positioned on cartridge assembly 222 and/or anvil assembly 224 in such a manner so as to not increase an outer circumferential profile of the distal ends thereof. In this manner, buttress attachment features 260 do not interfere with the placement of the distal end of surgical stapling device 200 at the target surgical site. For example, with buttress attachment features 260 positioned along knife channel "K" (as shown in FIGS. 9 and 10), buttress attachment features 260 do not, at any time, extend beyond an outer profile of distal ends of cartridge assembly 222 and/or anvil assembly 224.

Fingers 362 have a second position in which at least a distal or free end of fingers 362 extend substantially parallel to tissue contacting surface "T" of anvil plate 344 of anvil assembly 224, in a direction towards anvil pockets "P". While in the second position and when a surgical buttress "B" is in position against tissue contacting surface "T" of anvil plate 344 of anvil asseinbly 322, fingers 362 are oriented so as to prevent movement and/or removal of surgical buttress "B" relative to and/or from tissue contacting surface "T" of anvil plate 344 of anvil assembly 322.
While buttress attachment feature 360 has been described as associated with anvil assembly 322, a further buttress attachment feature may be provided and associated with cartridge asseinbly 320, not shown.
At least fingers 362 of buttress attachment feature 360 is fabricated from a shape memory alloy (i.e., Nickel Titanium, NiTi, Nitiilol, etc.), a shape memory polymer, or any other suitable material exhibiting shape memory properties during elevated temperatures.
Use of buttress attachment feature 360 is substantially similar to use of buttress attachment feature 160 and thus, in the interest of brevity, will not be described in extensive detail hereinbelow.
In use, with buttress attachment features 360 at a first teinperature, fingers 362 are oriented in the first position, as described above. With fingers 362 in the first position, a surgical buttress "B" may be placed in position against tissue contacting surfaces "T" of anvil plate 344 of anvil assembly 322. With surgical buttress "B" so positioned, the temperature in the proximity of anvil assembly 322 is varied from the first temperature to a second temperature, i.e., either elevated or reduced relative to the first temperature. At the second temperature, buttress attachment feature 360 undergoes a phase transformation, as described above, wherein free ends of fingers 362 move to the second position, as described above, to secure, maintain, retain or otherwise hold surgical buttress "B" in contact and in position on tissue contacting surface "T" of anvil plate 344 of anvil assembly 322.
As seen in FIG. 12, free ends of fingers 362 are shown in a first position near a free end of anvil assembly 322 and in a second position near a rear end of anvil assembly 322.

In the second position and with a surgical buttress "B" in position against tissue contacting surface "T" of any of the distal end of carti-idge receiving half-sectioii 112, distal end of anvil half-section 114, cartridge assembly 116 and anvil plate 144, fingers 162 are oriented so as to prevent movement and/or removal of surgical buttress "B" relative to and/or from tissue contacting surfaces "T" of any of the distal end of cartridge receiving half-section 112, distal end of anvil half-section 114, cartridge assembly 116 and anvil plate 144.
At least fingers 162 of buttress attachment feature 160 is fabricated fronl a shape memory alloy (i.e., Nickel Titanium, NiTi, Nitinol, etc.), a shape memory polymer, or any other suitable material exhibiting shape memory properties during elevated temperatures. Shape memory alloys, such as NiTi, undergo a phase transformation (i.e., austenite to martensite and vise versa) during temperature fluctuations (i.e., increases and decreases).
In use, as seen in FIGS. 1 and 2, with buttress attachinent features 160 at a first temperature, fingers 162 are oriented in the first position, as described above. With fingers 162 in the first position, a surgical buttress "B" inay be placed in position against tissue contacting surfaces "T" of anvil plate 144 aiid/or cartridge assembly 116. With surgical buttress "B" so positioned, the temperature in the proximity of the distal ends of cartridge receiving half-section 112 and/or anvil half-section 114 is varied from the first temperature to a second temperature, i.e., either elevated or reduced relative to the first temperature. At the second temperature, buttress attachment features 160 undergo a phase transformation, as described above, wherein free ends of fingers 162 move to the second position, as described above, to secure, maintain, retain or otherwise hold surgical buttress "B" in contact and in position on tissue contacting surface "T" of cartridge half-section 112 and/or anvil half-section 114.
In one embodiment, surgical buttress "B" is configured aiid sized such that fingers 162 of buttress attachment features 160 are disposed along outer edges thereof, when in the first position, and the distal ends of fingers 162 deflect down atop a tissue contact surface of surgical buttress "B" when in the second position. In another embodiment, fingers 162 of buttress attachment features 160, when in the first position, may extend substantially orthogonally from tissue contacting surfaces "T" of cartridge assembly 116 and/or anvil plate 144 at a location disposed between a side edge thereof and knife channel "K". In this embodiment, surgical buttress "B" is positioned against tissue contacting surfaces "T" of cartridge assembly 116 and/or anvil plate 144 such that fingers 162 penetrate therethrough (not shown). Moreover, in this embodiment, when the distal ends of fingers 162 are in the second position, the distal ends of fingers 162 may extend toward and/or away from knife channel "K".
In another einbodiment, fingers 162 of buttress attachment features 160, as described above, may be positioned along a length of knife channel "K". In this embodiment, surgical buttress "B" is positioned against tissue contacting surfaces "T" of cartridge assembly 116 and/or anvil plate 144 such that fingers 162 penetrate therethrough (not shown). Moreover, in this embodiment, when the distal ends of fingers 162 are in the second position, the distal ends of fingers 162 may extend away from knife channel "K".
With surgical buttress "B" so positioned, the distal end of surgical stapling device 100 may be positioned at the target surgical site with surgical buttress "B"
securely held in position against tissue contacting surfaces "T" of cartridge assembly 116 and/or anvil plate 144. Surgical buttress "B" is properly positioned when at least a substantial portion of staple pockets "P" is covered thereby.
Buttress attachment features 160 may be positioned on cartridge receiving half-section 112 and/or anvil half-section 114 in such a manner so as to not increase an outer circumferential profile of the distal ends thereof. In this manner, buttress attachment features 160 do not interfere with the placement of the distal end of surgical stapling device 100 at the target surgical site. For example, with buttress attachment features 160 positioned along knife channel "K" (as shown in phantom in FIGS. 2 and 3), buttress attachment features 160 do not, at any time, extend beyond an outer profile of distal ends of cartridge receiving half-section 112 arid/or anvil half-section 114.
Turning now to FIGS. 4 and 4A, a buttress attachment feature, according to another embodiment of the present disclosure, is generally designated as 160a.
As shown in FIGS. 4 and 4A, a pair of buttress attachment features 160a extend from opposed sides of distal ends of cartridge receiving half-section 112 and/or anvil half-section 114, however, it is contemplated that in an embodiment, buttress attachment features 160a inay extend from knife channel "K" (see FIGS. 5 and 5A).
Each buttress attachment feature 160a includes a plurality of ribs 162a each having a first end positioned on sides of distal ends of cartridge receiving half-section 112 and/or anvil half-section 114 at a location proximate a mid-point thereof, and a second end extending away from sides of distal ends of cartridge receiving half-section 112 and/or anvil half-section 114 and extending along an entire length of the distal ends of cartridge receiving half-section 112 and/or anvil half-section 114, thereby defining a fan-like configuration. Each buttress attachment feature 160a further includes a panel 166a of suitable biocompatible mesh-like material disposed over ribs 162a.
While separate surgical buttresses "B" are shown positioned over staple pockets "P", it is envisioned and contemplated that panels 166a of buttress attachment features 160a may function as the surgical buttresses "B".
As seen in FIG. 4, buttress attachment features 160a have a first position in which ribs 162a and panels 166a are oriented substantially orthogonal relative to tissue contacting surfaces "T" of cartridge assembly 116 and/or anvil plate (not shown). In this orientation, surgical buttresses "B" may be positioned at least partially over staple pockets "P".
As seen in FIG. 4A, buttress attachinent features 160a have a second position in which ri.bs 162a and panels 166a are oriented substantially parallel relative to tissue contacting surfaces "T" of cartridge assembly 116 and/or anvil plate (not shown). In this orientation, ribs 162a and panels 166a function to maintain surgical buttresses "B" in position against tissue contacting surfaces "T" of cartridge assembly 116 and/or anvil plate (not shown).
Altei-natively, if panels 166a are to function as surgical buttresses "B", positioning of ribs 162a and panels 166a to the second position results in placement of the surgical buttress into position against tissue contacting surfaces "T" of cartridge assembly 116 and/or anvil plate (not shown).
In the present embodiment, ribs 162a may be fabricated from suitable shape meinory materials in a manner similar to fingers 162 disclosed above. In this manner, buttress attachmeilt features 160a may be oriented from the first to the second position, as needed, with a change in the temperature thereof.
Turning now to FIGS. 6 and 6A, a buttress attachment feature, according to another embodiinent of the present disclosure, is generally designated as 160b. As shown in FIGS. 6 and 6A, a pair of buttress attachment features 160b extend from opposed sides of distal ends of cartridge receiving half-section 112 and/or anvil half-section 114, however, it is contemplated that in an embodiment, buttress attachmcnt fcatures 160b may extend from knife channel "K" (not shown).
Each buttress attachment feature 160b includes a frame 162b having legs 168b which extend from opposed sides of distal ends of cartridge receiving half-section 112 and/or anvil half-section 114, at a location proximate a mid-point thereof, and a drape 166b supported on and extending over frame 162b. Drape 166b may be fabricated from a suitable biocompatible mesh-like material. In this manner, drape 166b may take the place of surgical buttress "B". However, if desired, a separate surgical buttress "B" may be used in conjunction with buttress attachment feature 160b.
As seen in FIG. 6, buttress attachment features 160b have a first position in which frame 162b and drapes 166b are oriented substantially orthogonal relative to tissue contacting surfaces "T" of cartridge asseinbly 116 and/or anvil plate (not shown). In this orientation, drapes 166b do not overlie staple pockets "P". Also, in this orientation, separate surgical butti-esses (not shown) may, if being used, be positioned at least partially over staple pockets "P".
As seen in FIG. 6A, buttress attachment features 160b have a second position in which frame 162b and drapes 166b are oriented substantially parallel relative to tissue contacting surfaces "T" of cartridge assembly 116 and/or anvil plate (not shown). In this orientation, drapes 166b overlie staple pockets "P" and may act as a surgical buttress.
Also, in the present orientation, if a separate surgical buttress (not shown) has been positioned over staple pockets "P" of cartridge assembly 116 and/or anvil plate, frame 162b and drapes 166b function to maintain the separate surgical buttress in position against tissue contacting surfaces "T" of cartridge assembly 116 and/or anvil plate (not shown).
In the present embodiment, frames 162b may be fabricated from suitable shape memory materials in a manner similar to fingers 162 disclosed above. In this manner, buttress attachment features 160b may be oriented from the first to the second position, as needed, with a change in the temperature thereof.
It is contemplated that legs 168b of each buttress attachment feature 160b may extend froin knife channel "K", at a location proximate a mid-point thereof.

Fingers 262 have a first. position in which fingers 262 extend substantially orthogonal relative to tissue contacting surface "T" of cartridge assembly 222 and/or anvil assembly 224. While in the first position, fingers 262 are oriented so as to enable and/or allow placement anci/or removal of surgical buttress "B" into or out of contact with tissue contacting surfaces "T".
Fingers 262 have a second position in which at least a distal or free end of fingers 262 extend substantially parallel to tissue contacting surface "T" of cartridge assembly 222 and/or anvil assembly 224, in a direction towards staple pockets "P" (see FIG. 10) or anvil pockets "P" (see FIG. 9). While in the second position and when a surgical buttress "B" is in position against tissue contacting surface "T" of cartridge assembly 222 and/or anvil assembly 224, fingers 262 are oriented so as to prevent movement and/or removal of surgical buttress "B" relative to and/or from tissue contacting surfaces "T" of cartridge asseinbly 222 and/or anvil assembly 224.
At least fingers 262 of buttress attachment feature 260 is fabricated from a shape memory alloy (i.e., Nickel Titanium, NiTi, Nitinol, etc.), a shape memory polymer, or any other suitable material exhibiting shape memory properties during elevated temperatures.
Use of buttress attachment feature 260 is substantially similar to use of buttress attachment feature 160 and thus, in the interest of brevity, will not be described in extensive detail hereinbelow.
In use, with buttress attacliment features 260 at a first temperature, fingers 262 are oriented in the first position, as described above. With fingers 262 in the first position, a surgical buttress "B" may be placed in position against tissue contacting surfaces "T" by placing surgical buttress "B" between fingers 262, as seen in FIG. 8, or by penetrating fingers 262 through surgical buttress "B", as seen in FIGS. 9 and 10. With surgical buttress "B" so positioned, the temperature in the proximity of cartridge assembly 222 and anvil assembly 224 is varied from the first temperature to a second temperature, i.e., either elevated or reduced relative to the first temperature. At the second temperature, buttress attachmeilt features 260 undergo a phase transformation, as described above, wherein free ends of fingers 262 move to the second position, as described above, to secure, tnaintain, retain or otherwise hold surgical buttress "B" in contact and in position on tissue contacting surface "T" of cartridge assembly 222 and anvil assembly 224.
