Embolectomy procedures with a device comprising a polymer and devices with polymer matrices and supports
First Claim
1. A method for the removal of thrombus with an embolectomy device comprising a guide structure and a plurality of fibers operably connected to the guide structure, the method comprising moving the embolectomy device within a vessel of a patient to dislodge thrombus with the embolectomy device wherein suction is applied within the vessel to remove at least a portion of the dislodged thrombus.

Abstract
Embolectomy procedures can be performed under conditions to effectively remove thrombus/emboli with little risk of injuring the vessel wall and while effectively capturing and removing emboli. Desired embolectomy devices present a polymer matrix against the vessel wall. Suction can be used to facilitate the embolectomy process and to remove emboli loosened in the procedure. Some devices combine features to present a polymer matrix against the vessel wall while corresponding providing sufficient support to effectively loosen thrombus. Combinations of embolectomy and/or filter elements can be used.

16. A method for the removal of thrombus with an embolectomy device comprising a guide structure, an embolectomy device comprising a polymer matrix and a filter comprising a three-dimensional filtration matrix having a deployed configuration with the filtration matrix extending across the lumen of a vessel, the method comprising moving the embolectomy device within a vessel of a patient to dislodge thrombus while the filter is in its deployed configuration at a fixed location within the vessel.
- 17. A biocompatible filtration device comprising a guide structure having a proximal end and a distal end, a three dimensional filtration matrix connected near the distal end of the guide structure and a porous filtration membrane connected to the guide structure distal to the three dimensional filtration matrix.
-
26. A biocompatible filtration device comprising a guide structure having a proximal end and a distal end, a three dimensional filtration matrix connected near the distal end of the guide structure and a support structure interfaced with the three dimensional filtration matrix to form a filter element having a deployed configuration and a recovery configuration, wherein in the deployed configuration the three dimensional filtration matrix extends outward from the support structure with respect to the filtering function of the device relative to the axis of the guide structure.
-
27. A biocompatible embolectomy device comprising a guide structure having a proximal end and a distal end, a plurality of polymeric fibers connected near the distal end of the guide structure and a support structure wherein the fibers interface with the support structure to reinforce the fibers, wherein the fibers have a deployed configuration and a recovery configuration and wherein in the deployed configuration the polymeric fibers extend outward from the support structure relative to the axis of the guide structure.
- 28. An embolectomy device comprising a tubular catheter having a distal end and a proximal end with a lumen extending from the proximal end to an aspiration port at or near the distal end, an aspiration apparatus operably connected at or near the proximal end of the tubular catheter and a plurality of fibers connected to the surface of the catheter at a localized section within 10 centimeters from the distal end of the catheter.
-
31. A method for removing debris from a vessel of a patient, the method comprising sweeping an embolectomy device through a deployed stent within a patient'"'"'s vessel and applying suction to remove debris loosened by the embolectomy device.
