Abstract
A device and method for treatment of a tissue specimen disposed in surrounding tissue has a tissue specimen isolating toot and a tissue specimen damager. The tissue specimen isolating tool isolates the tissue specimen from the surrounding tissue. The tissue specimen damager damages the tissue, with a possible end result being necrosis. The severing tool may have a cutting member that is extendable to an outwardly radially bowed position about device. The tissue specimen is isolated by rotating the cutting member about the tissue specimen. The cutting member may be functionally connected to a cutting member radio frequency generation source.

FIG. 2 shows a sectional view of the device ofFIG. 1 in a breast after isolation of the tissue specimen and prior damaging the tissue specimen; -
FIG. 3 shows the same sectional view as doesFIG. 2 but after damaging the tissue specimen by thermal treatment; -
FIG. 4 is a nonexclusive chart of treatment methods for damaging the tissue specimen according to embodiments of the invention; and -
FIGS. 5-8 are side views of tissue specimen isolating and damaging devices according to various embodiments of the invention. -
FIGS. 9 and 10 show tissue specimen encapsulation devices which may be used in conjunction with the invention. -
FIG. 11 is a sectional radial view of the device shown inFIGS. 9 and 10 in a target body with the sheath deployment members being partially deployed in a periphery margin surrounding the tissue specimen. -
FIG. 12 is a perspective view of the device ofFIGS. 9 and 10 shown without an outer sleeve and with sheath deployment members and a cutting member bowed radially outward. - Referring now to the figures, and specifically to
FIG. 1 , a tissue specimen isolating anddamaging device 10 comprises awand 12 having aproximal end 14 shown to the right and adistal end 16 shown to the left. Thedevice 10 is used to isolate a tissue specimen while the tissue specimen is disposed in surrounding tissue and then damage the tissue specimen (seeFIGS. 2 and 3 ). The isolation step may encompass isolating the tissue specimen from circulation and/or may encompass generally severing of the tissue specimen from the surrounding tissue. After the damaging step, the tissue specimen may remain in the body, turn into fibrotic tissue, and/or be removed from the body during the process or at a later time. - While isolating the tissue specimen may result in necrosis, the
device 10 damages the tissue specimen to insure necrosis occurs. The necrosis of the tissue specimen results in reducing or eliminating the transfer of malignant or diseased tissue from the tissue specimen. The necrosis of the tissue specimen also dissuades the patient's body from repairing the tissue specimen. The shown embodiment of the invention utilizes aradio frequency generator 18 to perform the procedure. Other embodiments of the invention may use other methods, examples of which are non-exclusively discussed below. - Located at the
distal end 16 of thewand 12 is anoperational portion 20 of thedevice 10. Theoperational portion 20 is involved with both isolating and damaging the tissue specimen. In the shown embodiment, an outwardly radially bowedwire 22 isolates the tissue specimen. Thewire 22 is disposed at theoperational portion 20 and rotationally connected to thewand 12. In the shown embodiment of the invention, thewire 22 is initially in a retracted position against the wand 12 (not shown) to reduce trauma to surrounding tissue during placement of thedevice 10. Thewire 22 is extended outward radially after theoperational portion 20 is disposed in or proximate to the tissue specimen. - The
wire 22, which is a tissue specimen isolating tool of thedevice 10, is powered by theradio frequency generator 18 and rotated to isolate the tissue specimen. As thewire 22 is rotated, a periphery channel (seeFIG. 2 ) is formed between the tissue specimen and the surrounding tissue, thus severing the two. Other embodiments of the invention may have thewire 22 be fixedly and not rotatably connected to thewand 12, thus the whole wand is rotated to isolate the tissue specimen and not just the bowedwire 22. - Embodiments of the invention may comprise other tissue specimen isolating tools with cutting members, such as is disclosed in commonly assigned U.S. patent applications to Burbank et al. entitled “Breast Biopsy System and Method,” U.S. patent application Ser. No. 09/057,303 and “Tissue Specimen Encapsulation Device and Method Thereof,” U.S. patent application Ser. No. 09/208,535, both of which are herein incorporated by reference in their entireties. Embodiments of the invention may only partially sever the tissue specimen from the surrounding tissue.
- At the
distal end 16 is aradio frequency wire 24 that is energized during the step of inserting thewand 12 into the surrounding tissue. Other embodiments may have other means for inserting the wand into the surrounding tissue, such as a nonenergized piercing tool or some other form of energized piercing tool. Still other embodiments of the invention may not have a piercing tool at thedistal end 16, but rather enter the surrounding tissue through a pre-existing passage. - In the shown embodiment, the tissue specimen is ablated or otherwise damaged after isolation (see
FIG. 3 ). The damaging of the tissue sample results in necrosis. The damage may be caused by ionizing radiation that disrupts cellular functions. The tissue specimen may be damaged through mechanical means, such as cutting or otherwise morcellating the tissue specimen. Tissue specimen damage may be the result of thermal or chemical treatment. - Continuing to refer to
FIG. 1 ,radio frequency wires 28 that extend from theoperational portion 20 of thedevice 10 are used to damage the tissue specimen. Thewires 28 are initially in a retracted position inwand 12 or disposed on thewand 12. Either before, during, or after the isolation of the tissue specimen, thewires 28 are extended as shown and enter the tissue specimen. In a preferred embodiment of the invention, thewires 28 are disposed in thewand 12 and are extended prior to isolation of the tissue specimen. Theextended wires 28 anchor thedevice 10 in the tissue specimen, resulting in a more precise isolation of the specimen. Other embodiments of the invention may have other methods or mechanisms for anchoring, thedevice 10 in the tissue specimen. - The
radio frequency wires 28, which comprise the tissue specimen damager ofdevice 10, are shown extending toward thedistal end 16 of thewand 12. Other embodiments of the invention may havewires 28 extending in any suitable direction. Thewires 28 are shown extending almost to the radially bowedwire 22, resulting in thewires 28 being distributed throughout the tissue specimen. Other embodiments of the invention may have thewires 28 extending into a portion of the tissue specimen. - When energized, the radio frequency wires 29 damage the tissue specimen by causing the water molecules in the tissue specimen to vibrate and rapidly vaporize. The rapid vaporization results in the destruction of cells in the tissue specimen, thus damaging the specimen. The rapid vaporization is a form of thermal treatment. The radio frequency wires may be mono- or bi-polar.
- After treatment, the
wires 28 may be retracted into thewand 12. Other embodiments of the invention may not have thewires 28 being retracted, but rather thewires 28 remain extended and slide out of the tissue specimen during removal of thewand 12 from the surrounding tissue. Thedistally leaning wires 28 facilitate their sliding out of the tissue specimen during wand removal. - The severing and isolation of the tissue specimen results in a more controlled and simpler process to damage the specimen. In the case of thermal treatment, a non-isolated tissue specimen is cooled or heated by blood circulating through the specimen. The thermal treatment of an isolated tissue specimen is not competing with the cooling or heating effects of blood circulation. Without competing with the effects of blood circulation through the specimen, the thermal treatment is shorter and more restricted to the immediate tissue specimen. Further, the isolation reduces thermal damage to the surrounding tissue.
- Functionally connected to the
proximal end 14 of thewand 12 is acontrol system 30. In the shown embodiment, thecontrol system 30 manipulates thecutting wire 22 and theradio frequency wires 28. In some embodiments of the invention, thecontrol system 30 may control the insertion and removal of thewand 12 from the tissue specimen and the surrounding tissue. Thecontrol system 30 is functionally connected to theradio frequency generator 18 that supplies energy to thewires wire 22 is in a fixed position on thewand 12, thecontrol system 30 rotates thewand 12 to isolate the tissue specimen. In other embodiments of the invention, the components of the device are manipulated by hand. - Referring now to
FIG. 2 , thedevice 10 is shown disposed in abreast 50 with theoperational portion 20 being disposed in atissue specimen 52. In this embodiment, thebreast 50 may be considered the surrounding tissue. Thetissue specimen 52 contains atumor 54, which is shown cross-hatched. Thecutting wire 22 is shown in the outwardly radially bowed position. Thecutting wire 22 has already been rotated, thereby forming aperiphery channel 56 and isolating thetissue specimen 52. Note theradio frequency wires 28 are not shown extended inFIG. 2 . In a preferred embodiment of the invention, thewires 28 are extended into thetissue specimen 52 prior to isolation. - Referring now to
FIG. 3 , thetissue specimen 52 ofFIG. 2 has been damaged, resulting in damagedtissue specimen 60 through thermal treatment by thedevice 10. Theradio frequency wires 28 of thedevice 10 are shown extended into thetissue specimen 60. Thewires 28 had been energized, resulting in the vaporization of the water molecules, disruption of the cells of the tissue specimen, heating the specimen, and the ultimate damaging of it. The amount and time of the treatment may be predetermined or the device may comprise a feed back system (not shown) that indicates when the treatment has been completed. In a further step, thedevice 10 is removed from thebreast 50, either without or without retracting theradio frequency wires 28 into thedevice 10. - Referring now to
FIG. 4 ,Chart 100 is a non-exclusive list of possible methods for damaging the in vivo tissue specimen besides thermal treatment through radio frequency devices. Listed as forms ofthermal treatments 102 are laser, hot fluids, cold fluids, radio frequency energy and other electrosurgery techniques, microwave, focussed ultrasound, mechanical ultrasound, shock waves, resistive heating, cryosurgery using liquid or gas, cauterizing, and the application of a heated object. An example of a heated object is disclosed in U.S. Pat. No. 4,773,413 to Hussein et al. entitled “Localized Heat Applying Medical Device,” which is incorporated herein by referenced in its entirety. Other embodiments of the invention may use any suitable thermal treatment system to damage the tissue specimen. - The
mechanical treatment list 104 includes morcellators and other cutting devices. The ionizingradiation treatment list 106 includes treatment with x-rays, including x-ray needles, gamma rays, and Brachytherapy seeds, which are forms of ionizing radiation directors. Thechemical treatment list 108 includes treatment with ethanol, sotradechol, an acid, a base, various chemical compounds, various chemical mixtures, a catalyst, a sealing agent that seals the outside of the tissue specimen, and a photoreactive chemical that is used in conjunction with a light or laser system. Other embodiments of the invention may use any suitable chemical treatment system to damage the tissue specimen. - Referring now to
FIG. 5 , a tissue specimen isolating anddamaging device 200 has alaser device 202 at anoperational portion 204. Thelaser device 202 damages a tissue specimen through thermal treatment. The shown embodiment of the invention has two outwardly radially bowed cuttingwires 206. Embodiments of the invention may have one ormore cutting wires 206 regardless of the treatment to damage the tissue specimen. Note that acutting tip 210 is located at adistal end 212 of thedevice 200. - Referring now to
FIG. 6 , a tissue specimen isolating, anddamaging device 220 has amorcellator 222 at anoperational portion 224. Themorcellator 222 is used to morcellate a tissue specimen. The tissue specimen may be morcellated after encapsulation of the tissue specimen. Encapsulation of the tissue specimen is disclosed in the previously referenced and incorporated U.S. patent application Ser. No. 09/208,535 entitled “Tissue Specimen Encapsulation Device and Method Thereof”. The tissue specimen may be encapsulated with non-biodegradable or biodegradable material. Note that there is not a piercing tool on this embodiment of the invention. Other morcellating devices may have a piercing tool. Also note that the cutting wire is in a retracted position and not visible. - In an embodiment of the invention, the tissue specimen is damaged by encapsulation. The damage is the result of the tissue specimen being physically isolated from the surrounding tissue. In an embodiment of the invention, a sheath may at least partially surround the tissue specimen (not shown). In another embodiment of the invention (not shown), the tissue specimen may be physically isolated by encapsulation accomplished with a chemical that flows into the periphery channel about the tissue specimen and seals specimen's outside surface. Suitable techniques known in the art for ensuring a continuous distribution of the sealing chemical may be employed, such as pressurizing the periphery channel.
- Now referring to
FIG. 7 , a tissue specimen isolating anddamaging device 240 hasoutlets 242 at theoperational portion 244. Theoutlets 242 permit the flow of a chemical into the tissue specimen, thus transforming the tissue specimen through a chemical reaction or other chemical treatment. The isolation of the tissue specimen reduces the amount of chemicals transferring to the surrounding tissue. - In other embodiments of the invention, hollow needles may extend from the
operational portion 244 such that the chemical may be injected into the tissue specimen through the needles. Other embodiments of the invention may include slicing tools that make slits in the surface of the tissue specimen that is in contact with thewand 246. The slits facilitate infusion of the chemical. The slits may also be made by thecutting wire 248. Thecutting wire 248 is rotated and partially extended into the tissue specimen at periodic intervals either before or after the tissue specimen has been isolated. - Referring now to
FIG. 8 , a tissue specimen isolating anddamaging device 260 cryogenically treats thetissue specimen 262 disposed at theoperational portion 264 of thewand 266. A cryogenic fluid is flowed to theoperational portion 264 through afeed line 268 and is returned to the control system (not shown) via areturn line 270, both of which is disposed in thewand 266. Thetissue specimen 262 is frozen and damaged through thermal treatment with the cryogenic fluid. - Encapsulation of the tissue specimen may be accomplished by use of a tissue specimen encapsulation device as shown in
FIG. 9 . The figure depicts a tissuespecimen encapsulation device 310 which is comprised of awand assembly 312, asheath 314, and aguide assembly 316. Thewand assembly 312 defines anaxis 318, andaxial direction 320, and a plurality ofradial directions 322. Thewand assembly 312 also has aproximal end 324, shown to the left inFIG. 9 , and adistal end 326, shown to the right inFIG. 9 . Amidsection 328 extends between theends proximal end 324 is the end that is held by a user of thedevice 310. Theproximal end 324 may be functionally connected to an actuator system, such as a control box or the equivalent, that manipulates thedevice 310 per the directions of the user (not shown). Thedistal end 326 is inserted into a target body (not shown) and proximate to a tissue specimen to be encapsulated by the device. Thewand assembly 312 may be rigid or flexible, and may be articulatable so that it may be steered. Thewand assembly 312 comprises ashaft core 329,shaft 330, asheath sleeve 332 and anouter sleeve 334. Theshaft core 329,shaft 330 andsleeves shaft core 329 is inside theshaft 330 that is inside thesheath sleeve 332 that is inside theouter sleeve 334. Theshaft core 329 and theshaft 330 extend proximally and distally beyond thesleeves sheath sleeve 332 extends proximally beyond theouter sleeve 334 but theouter sleeve 334 extends distally beyond thesheath sleeve 332. In the device as shown, thedistal end 326 of the device has atip 338 with a radio frequency (“RF”)powered member 340 extending diametrically across the tip. The RF poweredmember 340 may be energized such that the device moves through tissue via ablation or electrosurgical incision, thus enabling the device to be inserted into the target body containing a tissue specimen to be encapsulated. The device also may enter the biological target via other means, such as lasers or other focussed light techniques, high pressure water, cutting with a sharp implement, cryogenic techniques, etc. In addition, the device may not have a component analogous to the RF poweredmember 340 but thedistal end 326 may be inserted into the target body through a pre-existing passage (not shown). The device also has a sheath deploymentrod deployment end 342 extending from theproximal end 324 of thewand assembly 312. The sheath deploymentmember deployment end 342 is pulled proximally in theaxial direction 320 to deploy thesheath 314 about a tissue specimen. InFIG. 10 , thesheath deployment members 448 are shown deployed about thetissue specimen 492. At the axial center of thewand 412 is the sheath deploymentmember deployment rod 456. The sheath deploymentmember deployment rod 456 extends distally through the sheathdeployment member cap 454 and terminates at thestop 488. Thestop 488 is located distally and adjacent to thecap top 476. The sheathdeployment member cap 454 is located at thedistal end 426 of thewand assembly 412 with theaxial extensions 478 extending proximally. Theaxial extensions 478 are disposed against the interior surface of theshaft core 429. The sheath deployment member deployment ends 474 are looped around the sheathdeployment member ring 482, which is located proximal to thecap top 476. Thesheath deployment members 448 extend from the sheathdeployment member ring 482 and radially out of thedistal end 426 of theshaft 430. As shown inFIG. 10 , the sheath deploymentmember deployment rod 456 is centrally located within theshaft core 429. Thepush rods 452 are disposed ingrooves 458 in the outer surface of theshaft core 429. Theshaft 430 surrounds theshaft core 429. Thetissue specimen 492 is disposed about theshaft 430 toward the shaft'sdistal end 426. Theouter sleeve 434 is shown surrounding theshaft 430 and is located proximally from thetissue specimen 492. Thesheath 414 is disposed between theshaft 430 and theouter sleeve 434 with thesecond portion 446 distally extending from under the outer sleeve. Thesheath deployment members 448 are deployed about thetissue specimen 492 but have not been released from thewand assembly 412. Theend balls 470 of thesheath deployment members 448 are disposed in the ball-holders 466. Thepush rods 452 have been pushed to a position proximal ofball openings 402. Theball openings 402 are located at the proximal end of each sheathdeployment member slot 472 and extend through theshaft 430. Theball openings 402 generally correspond with the proximal end of thetissue specimen 492. Thesheath deployment members 448 extend from theend balls 470, through theball openings 402, throughligatures 449 extending from the sheathsecond portion 446, and into theperiphery margin 498 about thetissue specimen 492. -
FIG. 11 shows the final sheath deployment member,sheath deployment member 448 d, partially radially expanded into thechannel 494 with 315 degrees of theperiphery margin 498 having been formed. The remainder of the method of deploying thesheath deployment members 448 and forming theperiphery margin 498 comprises fully extending thesheath deployment member 448 d to point 496 and rotating the device until the cuttingmember 488 reachespoint 496, thereby fully forming theperiphery margin 498 and separating thetissue specimen 492 from thetarget body 491. At this point the cuttingmember 488 may remain bowed or may retracted at least partially back to theshaft 430 by proximally pulling its respective push rod (not shown inFIG. 6 ). - Referring to
FIG. 12 , thesheath deployment members 448 are bowed radially outward. The bowing of thesheath deployment members 448 occurs as therespective push rods 452 are distally pushed while the distally located looped deployment end 474 (not shown, seeFIG. 5 ) of eachsheath deployment member 448 remains static. The pushing of therods 452 moves theend balls 470 distally in thegrooves 458 and forces thesheath deployment members 448 radially outward. Thesheath deployment members 448 extend throughligatures 449 attached to thesecond portion 446 of thesheath 414. As thesheath deployment members 448 bow outwardly, the sheath deployment members slip through the holes provided until theend balls 470 comes up against theligatures 449. Theligature 449 is a looped end of a cord 485 that is embedded in the sheathsecond portion 446. Theligature 449 is sized such that theend ball 470 cannot slide through it. Other embodiments of the invention may have other equivalent mechanisms and arrangements for attaching the sheath deploymentmember attachment end 471 to thesheath 414. - Also shown in
FIG. 12 is a bowed cuttingmember 488 which may be a radiofrequency powered tissue cutting element. The bowed cuttingmember 488 is shown as being similar to the foursheath deployment members 448. The cuttingmember 488 is disposed and arranged in the device 410 similar to thesheath deployment members 448. Initially, the cuttingmember 488 is not fully bowed. Using thefifth push rod 452, the cuttingmember 488 is forced radially outward throughslot 451. In the shown embodiment of the invention, the cuttingmember 488 is RF powered, as is themember 440 on thetip 438. Other embodiments of the invention may have cutting members that cut through tissue using other means. In some embodiments of the invention, the cutting member may be permanently attached to the distal end of thepush rod 452. In other embodiments of the invention, the cuttingmember 488 may also function similar to thesheath deployment members 448 in drawing thesheath 414 over the tissue specimen as described below. In still other embodiments of the invention, there may not be element of thedevice 10 that functions equivalently to the cuttingmember 488. - Embodiments of the invention have suitable control systems incorporated into the tissue specimen isolating and damaging device. Further, the embodiments of the invention are suitably configured for different treatment methods and different tissue specimen shapes and sizes.
- Although presently preferred embodiments of the present invention have been described in detail hereinabove, it should be clearly understood that many variations and/or modifications of the basic inventive concepts herein taught, which may appear to those skilled in the pertinent art, will still fall within the spirit and scope of the present invention, as defined in the appended claims.
