Description
- This patent claims benefit under 35 U.S.C. §119(e) to U.S. Provisional Patent Application Ser. No. 60/668,036 filed Apr. 4, 2005, the disclosure of which is hereby expressly incorporated herein by reference.
- This patent generally relates to filters for use in the treatment of vascular diseases, and more specifically to filters that include a removable filter head adapted to convert, in vivo, the filter from a filter configuration to an open, stent-like configuration.
- Convertible filters for treating vascular disease are known from the present inventor's own U.S. Pat. Nos. 6,267,776 and 6,517,559, the disclosures of which are hereby expressly incorporated herein by reference. These patents disclose numerous embodiments of convertible filters and particularly convertible filters suitable for treatment of vascular disease such as atherosclerotic and embolismic disease.
- Generally, convertible filters include a filter structure having a plurality of filter legs arranged to form a single or double cone filter basket within the vessel lumen to trap blood borne clots or plaque with the vessel. A release member releasable secures the legs or filtering elements of the filter structure such that the filter may have two distinct configurations: filter or open/stent-like. The conversion is affected by release of the release member from the filter legs allowing the spring action of the filter legs themselves or of an externally applied opening force, such the force of a spring coupled to the filter legs, to open the filter legs from the filter configuration to the stent-like configuration. The release member may be a biodegradable material that deteriorates over time to release the filter legs to move to the stent-like configuration.
- In another convertible filter, the release member is a mechanical retainer that includes a hook or similar grasping structure to allow the release member to be physically separated from the filter structure. Removal of the release member involves engaging the grasping structure with a snare and forcing the separation of the release member from the filter structure. The filter structure, which is typically attached to the wall by endothelial tissue, resists the applied force. The release member needs to be releasable from the filter legs with a minimum of force so that the reaction force exerted by the filter legs on the vessel wall does cause detrimental damage to the integrity of the wall. A well-designed release member will facilitate release of the member from the filter legs without transferring significant forces through the filter structure into the vessel wall.
- Upon separation of the release member from the filter legs, the filter structure opens to assume the stent-like configuration along the wall of the blood vessel.
- For a more complete understanding of the invention, reference should be made to the following detailed description and accompanying drawings wherein:
-
FIG. 1 illustrates a side view of an exemplary convertible filter assembly constructed in accordance with the teachings of the present invention; -
FIG. 2 illustrates the convertible filter assembly ofFIG. 1 aligned with a grasping device; -
FIG. 3 illustrates an enlarged view of a removable filter head portion of the convertible filter assembly cooperating with the grasping device in a retracted state; -
FIG. 4 illustrates an enlarged cross-sectional view of the removable filter head and grasping device ofFIG. 3 . -
FIG. 5 illustrates a cross-sectional view of the removable filter head taken along the line 5-5; -
FIG. 6 illustrates the enlarged cross-sectional view of the removable filter head and grasping device ofFIG. 4 shown in an unsecured position; -
FIG. 7 illustrates the enlarged cross-sectional view of the removable filter head and grasping device ofFIG. 6 after the release of the unsecured filter elements; -
FIG. 7 a illustrates the enlarged cross-sectional view of an alternative construction of the removable filter head and grasping device ofFIG. 6 after the release of the unsecured filter elements; and -
FIG. 8 illustrates a perspective view of the convertible filter assembly after separation of the removable filter head. - The removable filter head including a release mechanism constructed in accordance with the teachings of the present invention provides a safe system for converting, in vivo, a convertible filter, such as a vena cava filter, from a closed, filter configuration to an open, stent-like configuration.
- The removable filter head incorporates the release mechanism to releasably secure a plurality of interconnected intraluminal filter elements (filter elements) in a single or double cone filter structure or filter basket. The release mechanism includes a retainer adapted to receive the plurality of filter elements and a stopper movable, relative to the removable filter head and the retainer, between a secured position and an unsecured position. In operation, the filter elements are positioned within the retainer and held in position by, for example, the friction between the retainer, the filter elements and the stopper, when the stopper is in the secured position.
- Movement of the stopper, relative to the removable filter head and the retainer, from the secured position adjacent to the retainer to the unsecured position, releases the filter elements while maintaining the position of the removable filter head relative to the filter elements and the wall of the blood vessel. Subsequently, the released filter elements can convert or expand from the filter configuration to the stent-like configuration when the removable filter head is physically separated from the filter elements.
-
FIGS. 1-3 generally illustrate aconvertible filter assembly 10 deployed in a filter configuration within the lumen of ablood vessel 12. Theconvertible filter assembly 10 includes a plurality of intraluminal filter elements (filter elements) 14 secured in the filter configuration by aremovable filter head 16, as shown inFIG. 1 . The term “filter configuration” as used herein refers to theconvertible filter assembly 10 when positioned within theblood vessel 12 for the treatment of vascular diseases. Similarly, the terms “open configuration” or “stent-like configuration” refer to theconvertible filter assembly 10 with theremovable filter head 16 separated from thefilter elements 14, and theunrestrained filter elements 14 extended along awall 18 of theblood vessel 12. - The
filter elements 14 in this exemplary embodiment are arranged in a single cone configuration and aligned within theblood vessel 12 in the direction of the blood flow indicated by the arrow A to trap matter carried within the blood flow, for example, dislodged blood clots or plaque. Thefilter elements 14 each include afilter leg 20 flexibly attached to anorientation member 22 at aflexure point 24. In operation, deployment of theconvertible filter assembly 10 within theblood vessel 16 allows theorientation members 22 to engage thewall 18 of theblood vessel 12 and align the entireconvertible filter assembly 10 with the blood flow. However, it is noted that the particular configuration of the convertible filter, single cone, dual cone, basket, stabilizing members or no stabilizing members, etc., is not critical, and the herein described removable filter head is adaptable to virtually any such structure. - The
filter legs 20 include aninferior end 26 and asuperior end 28 aligned along thewall 18 of theblood vessel 12 by theorientation member 22. In particular, theinferior end 26 is an unsecured portion of thefilter leg 20 positioned upstream from thesuperior end 28. Thesuperior end 28 is, in turn, bundled and secured together by theremovable filter head 16 to form a filter basket generally indicated by thereference numeral 30. As used herein to assist the reader, the terms superior and inferior indicate the orientation of theconvertible filter assembly 10 within theblood vessel 12 and relative to the direction of the blood flow (indicated by the arrow A). For example, the term inferior indicates a downstream position and the term superior indicates an upstream position relative to the direction of blood flow within theblood vessel 12. - The
convertible filter assembly 10 including theremovable filter head 16, thefilter legs 20 and theorientation members 22 may be manufactured from a radiopaque and non-ferromagnetic metal that has been certified for use in medical devices by the International Standards Organization (ISO). Thefilter legs 20 and theorientation members 22 may be manufactured from metallic wires having, for example, a round, flat or any suitable cross-sectional shape. Theconvertible filter assembly 10 may be further drug-coated. - The wires may be a high cobalt, low ferrous alloy, such as the alloys sold under the registered trademark ELGILOY® which is also referred to as PHYNOX. The composition of these alloys may, by weight percent, be:
cobalt 42%, chromium 21.5%,nickel 18%, iron 8.85%, molybdenum 7.5%, manganese 2% with the balance made up of carbon and beryllium having a maximum of 0.15% carbon and 0.001% beryllium. The wires may also be composed of 316L stainless steel or other alloys of nickel and titanium known to be shape-memory metals which are sold and manufactured under the registered trademark NITINOL® or an alloy of tantalum (Ta).Convertible filter assemblies 10 constructed from these metals will be non-thrombogenic and preferably withstand twelve million respiratory cycles without mechanical failure. -
FIGS. 2 and 3 generally illustrate theconvertible filter assembly 10 deployed within theblood vessel 12 and aligned with asnare catheter 32. In particular,FIGS. 2 and 3 illustrate the alignment and capture of theremovable filter head 16 by thesnare catheter 32. Thesnare catheter 32, or any other suitable gripping device, can be inserted into the lumen of the blood vessel by any known method of insertion and deployment, and maneuvered through the patient's circulatory system to a position adjacent to theremovable filter head 16 and thesuperior end 28 of thefilter legs 20. Thesnare catheter 32 may include asheath 34 and asnare 36 such as, for example, a gooseneck snare or a hook, slideable relative to thesheath 34. Similarly, theremovable filter head 16 may include acatch 38 or hook adapted to be engaged by thesnare 34. -
FIG. 3 illustrates an enlarged view theremovable filter head 16 deployed within theblood vessel 12 and engaged by thesnare catheter 32. In particular,FIG. 3 shows thesnare catheter 32 maneuvered, via a patient's circulatory or cardiovascular system, to a position adjacent to theremovable filer head 16. From this position, thesnare 36 can loop around or otherwise grasp thecatch 38 to slideably secure thesnare catheter 32 andsheath 34 to theremovable filter head 16. By increasing the tension in the direction indicated by the arrow T, thesnare 36 can be retracted into thesheath 34 while simultaneously sliding thesheath 34 towards theremovable filter head 16. It will be understood that the applied tension T will be sufficient to withdraw thesnare 36 into thesheath 24, but not great enough to shift or disturb the overall position of theconvertible filter assembly 10 relative to thewall 18 of theblood vessel wall 12. -
FIG. 4 illustrates an enlarged cross-sectional view of thesnare catheter 32 in an abutting relationship withremovable filter head 16. Specifically, thesnare catheter 32 includes atip 40, defined as the terminal end of thesheath 34, in an abutting relationship with theremovable filter head 16. As shown, thetip 40 is firmly seated against theremovable filter head 16 and thesnare 36 and catch 38 are retracted into thehollow interior 42. - The
removable filter head 16 is a roughlycylindrical body 44 that includes an open first end 46 and a second end 48 that includes aretainer 50 formed integrally therein. The open first end 46 accepts anend cap 52 sized to close and/or seal the roughlycylindrical body 44. Theend cap 52 includes alip 56 which can be seated against atop edge 60 of thecylindrical body 44, and acylindrical wall 58 sized to cooperate with the interior surface of thecylindrical body 44 such that thelip 56 and atop edge 60 of thecylindrical body 44 are in an abutting relationship. Thecylindrical wall 58 and thecylindrical body 44 may be held together in a press-fit or friction arrangement, may include male and female threads and be rotatably joined and may be glued, welded or otherwise secured together in any desired manner. The end cap may further include an external,flat surface 54 arranged to bear against and/or bias thetip 40 of thesheath 34 when thesnare 36 and catch 38 are retracted into thehollow interior 42. Theflat surface 54 provides a firm contact between the two components, theremovable filter head 16 and thesnare catheter 32, and allows the transmission of forces therebetween. - The
end cap 52 further includes anorifice 62 sized to slideably accept arod portion 64 connected to thecatch 38. Therod portion 64 extends through theorifice 62 into an interior 66 of thecylindrical body 44 to engage astopper 70 having a contiguously formedshaft 68. Thestopper 70, as shown in this exemplary embodiment, is a roughly cylindrical component sized to releasably engage theretainer 50 formed at the second end 48 of thecylindrical body 44. In operation, thestopper 70 is movable within theinterior 66 of thecylindrical body 44 between a secured position adjacent to theretainer 50, and an unsecured position adjacent to theend cap 54. - The
stopper 70 includes varying diameter portions that define aflange 72 and plug 74. Theflange 74 and plug 74, of this present embodiment, are integral elements which are aligned coaxially with theshaft 68 and therod portion 64. Physically, theflange 72 is a radially extending disc that compliments the interior 66 of thecylindrical body 44 and theplug 74 has a reduced diameter, relative to theflange 72, sized to cooperate with theretainer 50 when thestopper 70 is in the secured position. Theshaft 68, as shown, may includes ablind bore 76 sized to securely accept therod portion 64 in, for example, a threaded or press fit arrangement. Theremovable filter head 16 may further include apush nut 78 positioned adjacent to thecylindrical wall 58 of theend cap 52 to hold thestopper 70, via theshaft 68 andflange 72, in secure contact with theretainer 50. - A force applied through the
catch 38 androd portion 62 in the direction indicated by the arrow T allows theshaft 68 to elastically deform thepush nut 78 and move thestopper 70 to the unsecured position adjacent 48 to thecylindrical wall 58 of theend cap 52. Thecylindrical wall 58 and pushnut 78 cooperate with theflange 72 to limit the overall movement of thestopper 70 to the unsecured position adjacent to theend cap 52. Theshaft 68 further includes a reduceddiameter portion 80 adjacent to theflange 72 and arranged to cooperate with thepush nut 78 to, upon movement to the unsecured position at the open first end 46, prevent thestopper 70 and plug from reengaging theretainer 50. - The
plug 74 and theretainer 50 cooperate to compressively engage and retain the superior ends 28 of thefilter legs 20 when thestopper 70 is in the secured position. Thesuperior end 28 of thefilter legs 20 may be aligned within a plurality of grooves 82 (seeFIG. 5 ) formed within theretainer 50 at the second end 48 of thecylindrical body 44. The alignedfilter legs 20 may, in turn, be held in position by inserting theplug 74 into theretainer 50 and creating an interference fit therebetween. Moreover, theflange 72 may be sized and arranged to compressively engage the aligned superior ends of thefilter legs 20 against theretainer 50. In this way, the superior ends 28 of thefilter legs 20 are aligned and secured within thecylindrical body 44 of theremovable filter head 16 to thereby create thefilter basket 30. -
FIG. 6 illustrates an enlarged cross-sectional view of theremovable filter head 16 in an abutting relationship with thetip 40 of thesnare catheter 32. In particular, thecatch 38 and thesnare 36 are withdrawn into thesheath 34 such that thetip 40 is firmly seated against theflat surface 54. Moreover, the application of tension through thesnare 26 and thecatch 38, in the direction indicated by the arrow T, forces thestopper 70 to move towards the unsecured position adjacent to theend cap 52. - The movement of the
stopper 70, in turn, causes theshaft 68 to bear against and elastically deform thepush nut 78. In particular, the stopper movement elastically deforms the fingers, indicated by thenumerals push nut 78. The elasticallydeformed fingers shaft 68 and engage a reduceddiameter portion 80 to prevent thestopper 70 from returning to the secured position adjacent to theretainer 50. Similarly, theflange 72 engages thecylindrical wall 58 and prevents additional movement or over-travel in the direction of theend cap 52. In this way, thestopper 70 is locked into the unsecured position away from theretainer 50 and between theend cap 52 and theretainer 50. The reduceddiameter portion 80 may further act as a detent such that as thestopper 70 arrives at the unsecured position, it is engaged by the reduced diameter portion to retain it in the unsecured position. The action of the fingers sliding from theshaft 68 to the reduced diameter portion may also provide a haptic snap or click indication through the catheter, allowing the medical professional to know that thestopper 70 is fully retracted to the unsecured position. - The tension applied to retract the
stopper 70 and elastically deform thepush nut 78, can cause the entireconvertible filter assembly 10 to move in order to react forces against theblood vessel wall 18. In order to limit force transfer to the vessel wall, the tension applied through thesnare 36 is counteracted and balanced by an equal and opposite force applied to theflat surface 54 through thesheath 34. In this way, while thecatch 38 and the attachedstopper 70 are forced to disengage from theretainer 50, the counterforce applied through thesheath 34 maintains the position of theremovable filter head 16 and attachedfilter elements 14, relative to theblood vessel wall 18. - As shown in
FIG. 6 , upon disengagement of theplug 74 from theretainer 50, thestopper 70 remains secured adjacent to theend cap 52 by the cooperation of the reduceddiameter portion 80 and thefingers push nut 78. The superior ends 28 of thefilter legs 20 will typically remain aligned within thegrooves 82 of theretainer 50, but will be unfettered and ready for release. This arrangement allowsconvertible filter assembly 10 to be transitioned from the filter configuration to the open or stent-like configuration by releasing the superior ends 28 of thefilter legs 20 from theretainer 50. - As outlined above, the process of transitioning the
convertible filter assembly 10 begins with maneuvering and aligning thesnare catheter 32 and thesnare 36 with theremovable filter head 16 and thecatch 38. The alignedsnare 36 engages thecatch 38, and thesheath 34 is positioned in contact with theflat surface 54 of theend cap 52. In this way, thetip 40 of thesnare catheter 32 abuts the removable filter head 16 (through contact with the end cap 52) and thesheath 34 encloses both thesnare 36 and thecatch 38. - Application of tension in the direction of the arrow T to the free end of the
snare 36, e.g., the end of thesnare 36 which is outside of the patient's body, pulls thecatch 38 deeper into thesheath 34 and forces the attachedstopper 70 to disengage from theretainer 50. It will be understood that unless the tension is greater than the force generated by thefingers push nut 78 and the friction between theplug 74 and theretainer 50, thestopper 70 cannot be disengaged. Simultaneously, a counterforce can be applied to theremovable filter head 16 through thesheath 34 in order to balance and counteract the effects of the tension applied through thesnare 36. In other words, as thesnare 36 is pulled to release theplug 74 from theretainer 50, thesheath 34 is pushed to engage theremovable filter head 16 through theflat surface 54 of theend cap 52 and prevent movement relative to theblood vessel wall 18. - By overcoming the friction between the
plug 74 and theretainer 50, theshaft 68 elastically deforms thefingers push nut 78 and allows thestopper 70 to move away from theretainer 70 and to the unsecured position adjacent to theend cap 52. Thefingers diameter portion 80 and lock or otherwise prevent thestopper 70 from reengaging theretainer 50. The movement of thestopper 70 is further limited, by the interference between theflange 72 and thecylindrical wall 58 of theend cap 52. This release mechanism within theremovable filter head 16 allows thestopper 70 to be disengaged from theretainer 50 and prevents unwanted reengagement of the components. -
FIG. 7 illustrates theremovable filter head 16 after thestopper 70 and plug 74 have been disengaged from theretainer 50. The unrestrained superior ends 28 of thefilter legs 20 have been released from thegrooves 82, and have flexed or expanded to the open or stent-like configuration. Generally, in order to disengage theremovable filter head 16 and release the superior ends 28 of thefilter legs 20, the entireremovable filter head 16 is pulled, via thesnare catheter 32, away from thefilter elements 14 lodged or encapsulated in thewall 18 of theblood vessel 12. In this way, theremovable filter head 16 and thesnare catheter 32 are separated from thefilter elements 14 for extraction through the patient's circulatory system. Thefilter elements 14 remain secured to thewall 18 of theblood vessel 12 in the open or stent-like configuration. -
FIG. 7 a illustrates an alternative construction of theremovable filter head 16 after the stopper and plug 74 have been disengaged from theretainer 50. Like reference numerals designate like elements. Theretainer 50 is formed with a smooth bore that receives the superior ends 28 of the filter legs. The stopper and plug 74 are formed withgrooves 82′ that engage and align the filter legs with the stopper and plug 74 in the secured position, and, as shown inFIG. 7 a, release the filter legs when in an unsecured position. Alternative arrangements whereingrooves 82/82′ are formed in one or both of theretainer 50 or plug 74 may be used. -
FIG. 8 illustrates the releasedintraluminal filter elements 14 expanded and extended along thewall 18 of theblood vessel 12. In this open or stent-like configuration, thefilter basket 30 is open and allows blood to flow freely through theblood vessel 12. - Although certain embodiments have been described in accordance with the teachings of the present disclosure, the scope and coverage of this patent is not limited thereto. For instance, while the
removable filter 14 has been illustrated and describes as having a cylindrical body, it will be understood that any desired shape or configuration may be employed. Further, while a specific embodiment of theintraluminal filter elements 14 has been described herein, many other single or double cone arrangements may be employed. This patent is intended to cover all embodiments of the teachings of the disclosure that fairly fall within the scope of the permissible equivalents.
