Definitions
- the present invention pertains to catheters for retrieving a distal protection filter. More precisely, the present invention pertains to retrieval catheters having a tapered distal tip.
- Heart disease is a major problem in the United States and throughout the world. Conditions such as atherosclerosis result in blood vessels becoming blocked or narrowed. This blockage can result in lack of oxygenation of the heart, which has significant consequences since the heart muscle must be well oxygenated in order to maintain its blood pumping action.
- Occluded, stenotic, or narrowed blood vessels may be treated with a number of relatively non-invasive medical procedures including percutaneous transluminal angioplasty (PTA), percutaneous transluminal coronary angioplasty (PTCA), and atherectomy.
- Angioplasty techniques typically involve the use of a balloon catheter. The balloon catheter is advanced over a guidewire such that the balloon is positioned adjacent a stenotic lesion. The balloon is then inflated and the restriction of the vessel is opened. During an atherectomy procedure, the stenotic lesion may be mechanically cut away from the blood vessel wall using an atherectomy catheter.
- embolic debris can be separated from the wall of the blood vessel. If this debris enters the circulatory system, it could block other vascular regions including the neural and pulmonary vasculature, both of which are highly undesirable. During angioplasty procedures, stenotic debris may also break loose due to manipulation of the blood vessel. Because of this debris, a number of devices, termed distal protection devices, have been developed to filter out this debris.
- the present invention pertains to distal protection filter retrieval catheters.
- the retrieval catheter may include an inner tube, an outer tube disposed over the inner tube, a lumen disposed between the inner tube and the outer tube, and a tapered member coupled to the lumen.
- the tapered member may include, for example, a distal tip or a rolling membrane movable between a first position and a second position.
- the first position may comprise the most appropriate position for advancing the catheter across, for example, a stent or lesion.
- the second position may comprise the most appropriate position for retrieving a distal protection filter. Shifting the tapered member between the first position and the second position may occur by, for example, altering fluid pressure, venting fluid, or infusing fluid into the lumen.
- FIG. 1 is a cross-section of a distal protection filter retrieval catheter disposed within a blood vessel including a tapered member in a first position;
- FIG. 2 is a cross-section of the distal protection filter retrieval catheter of FIG. 1 having the tapered member in a second position;

- FIG. 1 is a cross-section of a distal protection filter retrieval catheter 10 disposed within a blood vessel 12 and including a tapered member 14 configured in a first position. Removing a distal protection filter 16 from blood vessel 12 following an intravascular procedure may be complicated by a number of factors. For example, if the intravascular procedure includes the placement of a stent 18 adjacent a lesion 20 , a retrieval catheter may catch or otherwise engage stent 18 , which could lead to the displacement of stent 18 .
- distal protection filter retrieval catheter 10 has been designed to include a tapered member 14 that may assist passing catheter 10 past lesion 20 while causing minimal disruption of stent 18 .
- Catheter 10 includes an outer tube 22 disposed over an inner tube 24 and including an annular lumen 26 disposed therebetween.
- Outer tube 22 includes a proximal end 28 and a distal end 30 .
- Outer tube 22 may be comprised of a polymer, stainless steel or nickel-titanium alloy hypodermic tubing, or a composite thereof.
- outer tube 22 may be generally comprised of metals, polymers, or composites thereof.
- Inner tube 24 includes a proximal end 32 , a distal end 34 , and an inner lumen 36 extending therethrough. Similar to what is stated above for outer tube 22 , inner tube 24 may be comprised of metals, polymers, or composites thereof. Inner lumen 36 may comprise a guidewire lumen adapted and configured to have a guidewire, core wire, etc. disposed therein.
- Tapered member 14 may include a proximal end 42 and a tapered distal tip 44 . Tapered member 14 may be coupled to lumen 26 .
- tapered member may comprise a polymeric, metallic, or composite tubular member slidably disposed within lumen 26 .
- the position of tapered member may be maintained or otherwise altered by altering the pressure and/or the amount of fluid within lumen 26 .
- Tapered member 14 is movable between a first position and a second position.
- the first position is understood to be tapered member 14 configured such that at least a portion of distal tip 44 thereof extends beyond distal end 30 of outer tube 22 .
- the first position may be the most appropriate position for tapered member 14 when advancing catheter 10 across stent 18 or lesion 20 toward filter 16 .
- Distal protection filter 16 may be coupled to a generally metallic elongate shaft 38 , for example proximate a distal end 40 thereof.
- catheter 10 When using catheter 10 to retrieve filter 16 from blood vessel 12 , catheter 10 may pass over shaft 38 to a location proximate filter 16 .
- shaft 38 may extend through inner lumen 36 .
- Filter 16 and shaft 38 may generally comprise a number of configurations known to those skilled in the appropriate art.
- Filter 16 may be comprised of a polyurethane sheet and include at least one opening that may be, for example, formed by known laser techniques. The holes or openings are sized to allow blood flow therethrough but restrict flow of debris or emboli floating in the body lumen or cavity.
- Filter 16 may be generally cone-shaped, and have a proximal and a distal end.
- the distal end may be a narrow, “V”-shaped end and can be fixedly secured or formed to shaft 38 .
- the proximal end has a relatively wide opening.
- filter 16 may be cylindrical with a relatively rounded distal end.
- Filter 16 operates between a closed collapsed profile and an open radially-expanded deployed profile for collecting debris in a body lumen.
- Filter 16 may include a collapsible proximally-tapered frame having a mouth and a plurality of longitudinally-extending ribs. In an expanded profile, the mouth is opened and the ribs extend radially outwardly to support the mouth.
- filter 16 may comprise a number of differing objects including, but not limited to, a filter, a basket, a filter basket, a sheath, a capture sheath, a capturing device, one or more struts, one or more ribs, a mesh, a net, an expandable object, a self-expanding object, and combinations thereof.
- a number of differing configurations of filter 16 may be substituted without departing from the spirit of the invention.
- FIG. 2 is a cross-section of distal protection filter retrieval catheter 10 having tapered member 14 in a second position.
- the second position is understood to be tapered member 14 configured so that distal tip 44 may be disposed proximal to distal end 30 of outer tube 22 .
- the second position may be the most appropriate position for retrieving filter 16 . Accordingly, when tapered member 14 is in the second position, the inside diameter of tapered member may be sufficiently sized to accommodate filter 16 and allow removal thereof from blood vessel 12 .
- Inner tube 24 and outer tube 22 may be configured such that distal end 30 of outer tube 22 extends distally beyond distal end 34 of inner tube 24 .
- the length that outer tube 22 extending distally of inner tube may be sized appropriated for having filter 16 disposed therein. Shifting tapered member 14 from the first position to the second position would shift the inside diameter of catheter 10 from that of tapered member 14 or inner tube 24 to that of the inside diameter of outer tube 22 . Increasing the inside diameter of catheter 10 makes it possible for filter 16 to be disposed therein, either collapsed or partially collapsed.
- a clinician alters the fluid pressure or vent fluid from lumen 26 .
- a quantity of fluid may be disposed within lumen 26 that exerts a force upon tapered member 14 so as to hold it in the first position.
- catheter 10 With tapered member 14 in the first position, catheter 10 may be advanced across stent 18 or lesion 20 . Once catheter is positioned across stent 18 , the fluid can be vented from lumen 26 . Venting fluid from lumen 26 will essentially remove the force exerted by the fluid on tapered member 14 and allow it to shift to the second position. The actual shift may occur by a number of mechanisms. For example, once catheter 10 encounters filter 16 , proximal movement of filter 16 into catheter 10 may exert a force on tapered member 14 in the proximal direction and, thus, shift it into the second position.
- tapered member 14 may be biased to be in the second position (e.g., by a spring, etc.).
- force exerted upon tapered member 14 by the fluid may be acting to overcome the bias and hold tapered member 14 in the first position. Venting the fluid would allow the bias in position of tapered member 14 to shift tapered member 14 to the second position.
- FIG. 3 is a cross-section of an alternate distal protection filter retrieval catheter 110 having a tapered member 114 in a first position.
- Catheter 110 is essentially the same in form and function as catheter 10 except that tapered member 114 comprises a rolling membrane and that inner tube 124 and outer tube 122 are configured such that distal end 134 of inner tube 124 extends distally beyond distal end 130 of outer tube 122 .
- Tapered member 114 may be comprised of a polymer or combination of polymers extending between distal end 130 of outer tube 122 and distal end 134 of inner tube 124 and be generally tapered and having a relatively low profile. Tapered member 114 is in fluid communication with lumen 126 . Similar to what is described above, lumen 126 may include a fluid or other means for exerting force onto tapered member 114 . In alternate embodiments, tapered member 114 may be relatively inelastic or be elastic.
- tapered member 114 may be shifted between the first and the second positions by, for example, altering the fluid pressure, infusing fluid, or venting fluid from lumen 126 .
- the first position of tapered member 114 is understood to be where at least a portion of tapered member 114 is disposed proximal to distal end 134 of inner tube 124 .
- catheter 110 may be advanced across stent 18 or lesion 20 . Once catheter 110 is positioned across stent 18 , the fluid can be infused into lumen 126 . Infusing fluid into lumen 126 will exert a force on tapered member 114 and cause it to move or roll distally, and shift it to the second position.
- FIG. 4 is a cross-section of distal protection filter retrieval catheter 110 having tapered member 114 in a second position.
- the second position is understood to be a configuration of tapered member 114 wherein at least a portion thereof extends distally of distal end 134 of inner tube 124 .
- outer tube 122 may move distally relative to inner tube 124 . This movement may be due to force exerted by the fluid onto tapered member 114 being transferred to outer tube 122 .
- the position of outer tube 122 may be fixed relative to inner tube 124 .
- the first position of tapered member 114 would be the appropriate position for advancing tapered member 114 past lesion 20 or stent 18
- the second position is the position that would be appropriate for retrieving filter 16 .
- the second position would configure catheter 110 with an inside diameter (e.g., the inside diameter defined by tapered member 114 or outer tube 122 ) that is sized for having filter 16 disposed therein.

The detailed description and drawings illustrate example embodiments of the claimed invention.
-
FIG. 1 is a cross-section of a distal protectionfilter retrieval catheter 10 disposed within ablood vessel 12 and including atapered member 14 configured in a first position. Removing adistal protection filter 16 fromblood vessel 12 following an intravascular procedure may be complicated by a number of factors. For example, if the intravascular procedure includes the placement of astent 18 adjacent alesion 20, a retrieval catheter may catch or otherwise engagestent 18, which could lead to the displacement ofstent 18. To minimize the chance of disruptingstent 18 or any other interventions that may be presentadjacent lesion 20, distal protectionfilter retrieval catheter 10 has been designed to include atapered member 14 that may assist passingcatheter 10 pastlesion 20 while causing minimal disruption ofstent 18. -
Catheter 10 includes anouter tube 22 disposed over aninner tube 24 and including anannular lumen 26 disposed therebetween.Outer tube 22 includes aproximal end 28 and adistal end 30.Outer tube 22 may be comprised of a polymer, stainless steel or nickel-titanium alloy hypodermic tubing, or a composite thereof. Alternatively,outer tube 22 may be generally comprised of metals, polymers, or composites thereof. -
Inner tube 24 includes aproximal end 32, adistal end 34, and aninner lumen 36 extending therethrough. Similar to what is stated above forouter tube 22,inner tube 24 may be comprised of metals, polymers, or composites thereof.Inner lumen 36 may comprise a guidewire lumen adapted and configured to have a guidewire, core wire, etc. disposed therein. - Tapered
member 14 may include aproximal end 42 and a tapereddistal tip 44. Taperedmember 14 may be coupled tolumen 26. For example, tapered member may comprise a polymeric, metallic, or composite tubular member slidably disposed withinlumen 26. In addition, the position of tapered member may be maintained or otherwise altered by altering the pressure and/or the amount of fluid withinlumen 26. - Tapered
member 14 is movable between a first position and a second position. According to this embodiment, the first position is understood to be taperedmember 14 configured such that at least a portion ofdistal tip 44 thereof extends beyonddistal end 30 ofouter tube 22. The first position may be the most appropriate position fortapered member 14 when advancingcatheter 10 acrossstent 18 orlesion 20 towardfilter 16. -
Distal protection filter 16 may be coupled to a generally metallicelongate shaft 38, for example proximate adistal end 40 thereof. When usingcatheter 10 to retrievefilter 16 fromblood vessel 12,catheter 10 may pass overshaft 38 to a locationproximate filter 16. According to this embodiment, at least aportion shaft 38 may extend throughinner lumen 36. -
Filter 16 andshaft 38 may generally comprise a number of configurations known to those skilled in the appropriate art.Filter 16 may be comprised of a polyurethane sheet and include at least one opening that may be, for example, formed by known laser techniques. The holes or openings are sized to allow blood flow therethrough but restrict flow of debris or emboli floating in the body lumen or cavity. -
Filter 16 may be generally cone-shaped, and have a proximal and a distal end. The distal end may be a narrow, “V”-shaped end and can be fixedly secured or formed toshaft 38. The proximal end has a relatively wide opening. Alternatively,filter 16 may be cylindrical with a relatively rounded distal end. -
Filter 16 operates between a closed collapsed profile and an open radially-expanded deployed profile for collecting debris in a body lumen.Filter 16 may include a collapsible proximally-tapered frame having a mouth and a plurality of longitudinally-extending ribs. In an expanded profile, the mouth is opened and the ribs extend radially outwardly to support the mouth. In an alternate embodiment, filter 16 may comprise a number of differing objects including, but not limited to, a filter, a basket, a filter basket, a sheath, a capture sheath, a capturing device, one or more struts, one or more ribs, a mesh, a net, an expandable object, a self-expanding object, and combinations thereof. A number of differing configurations offilter 16 may be substituted without departing from the spirit of the invention. -
FIG. 2 is a cross-section of distal protectionfilter retrieval catheter 10 having taperedmember 14 in a second position. The second position is understood to be taperedmember 14 configured so thatdistal tip 44 may be disposed proximal todistal end 30 ofouter tube 22. The second position may be the most appropriate position for retrievingfilter 16. Accordingly, when taperedmember 14 is in the second position, the inside diameter of tapered member may be sufficiently sized to accommodatefilter 16 and allow removal thereof fromblood vessel 12. -
Inner tube 24 andouter tube 22 may be configured such thatdistal end 30 ofouter tube 22 extends distally beyonddistal end 34 ofinner tube 24. The length thatouter tube 22 extending distally of inner tube may be sized appropriated for havingfilter 16 disposed therein. Shifting taperedmember 14 from the first position to the second position would shift the inside diameter ofcatheter 10 from that of taperedmember 14 orinner tube 24 to that of the inside diameter ofouter tube 22. Increasing the inside diameter ofcatheter 10 makes it possible forfilter 16 to be disposed therein, either collapsed or partially collapsed. - To shift tapered
member 14 between the first and the second positions, a clinician alters the fluid pressure or vent fluid fromlumen 26. For example, a quantity of fluid may be disposed withinlumen 26 that exerts a force upon taperedmember 14 so as to hold it in the first position. With taperedmember 14 in the first position,catheter 10 may be advanced acrossstent 18 orlesion 20. Once catheter is positioned acrossstent 18, the fluid can be vented fromlumen 26. Venting fluid fromlumen 26 will essentially remove the force exerted by the fluid on taperedmember 14 and allow it to shift to the second position. The actual shift may occur by a number of mechanisms. For example, oncecatheter 10 encounters filter 16, proximal movement offilter 16 intocatheter 10 may exert a force on taperedmember 14 in the proximal direction and, thus, shift it into the second position. - Alternatively, tapered
member 14 may be biased to be in the second position (e.g., by a spring, etc.). According to this embodiment, force exerted upon taperedmember 14 by the fluid may be acting to overcome the bias and hold taperedmember 14 in the first position. Venting the fluid would allow the bias in position of taperedmember 14 to shift taperedmember 14 to the second position. -
FIG. 3 is a cross-section of an alternate distal protectionfilter retrieval catheter 110 having a taperedmember 114 in a first position.Catheter 110 is essentially the same in form and function ascatheter 10 except that taperedmember 114 comprises a rolling membrane and thatinner tube 124 andouter tube 122 are configured such thatdistal end 134 ofinner tube 124 extends distally beyonddistal end 130 ofouter tube 122. -
Tapered member 114 may be comprised of a polymer or combination of polymers extending betweendistal end 130 ofouter tube 122 anddistal end 134 ofinner tube 124 and be generally tapered and having a relatively low profile.Tapered member 114 is in fluid communication withlumen 126. Similar to what is described above,lumen 126 may include a fluid or other means for exerting force onto taperedmember 114. In alternate embodiments, taperedmember 114 may be relatively inelastic or be elastic. - Similar to what is described above, tapered
member 114 may be shifted between the first and the second positions by, for example, altering the fluid pressure, infusing fluid, or venting fluid fromlumen 126. The first position of taperedmember 114 is understood to be where at least a portion of taperedmember 114 is disposed proximal todistal end 134 ofinner tube 124. With taperedmember 114 in the first position,catheter 110 may be advanced acrossstent 18 orlesion 20. Oncecatheter 110 is positioned acrossstent 18, the fluid can be infused intolumen 126. Infusing fluid intolumen 126 will exert a force on taperedmember 114 and cause it to move or roll distally, and shift it to the second position. -
FIG. 4 is a cross-section of distal protectionfilter retrieval catheter 110 having taperedmember 114 in a second position. The second position is understood to be a configuration of taperedmember 114 wherein at least a portion thereof extends distally ofdistal end 134 ofinner tube 124. When taperedmember 114 shifts from the first position to the second position,outer tube 122 may move distally relative toinner tube 124. This movement may be due to force exerted by the fluid onto taperedmember 114 being transferred toouter tube 122. Alternatively, the position ofouter tube 122 may be fixed relative toinner tube 124. - It can be appreciated that the first position of tapered
member 114 would be the appropriate position for advancing taperedmember 114past lesion 20 orstent 18, and the second position is the position that would be appropriate for retrievingfilter 16. According to this embodiment, the second position would configurecatheter 110 with an inside diameter (e.g., the inside diameter defined bytapered member 114 or outer tube 122) that is sized for havingfilter 16 disposed therein. - It should be understood that this disclosure is, in many respects, only illustrative. Changes may be made in details, particularly in matters of shape, size, and arrangement of steps without exceeding the scope of the invention. The invention's scope is, of course, defined in the language in which the appended claims are expressed.
