Abstract: Described are devices and methods for medically sealing a perivalvular leak associated with implanted valves. For example, a bioresorbable tissue infiltratable sheet is provided for insertion through a perivalvular leak. A filament extending through the sheet is also provided which when pulled causes the sheet to gather around the filament on either side of the perivalvular leak. The gathered position of the sheet may be secured by a series of stops and/or use of a capping member.

Abstract: There are disclosed embodiments of a system for retrieving a filter device from within a patient. A tube or sheath and one or more cables or other elongated members, which include a protrusion such as a bead at or adjacent a distal end, are movable with respect to each other. When the tube or sheath is adjacent a filter device, the cable or elongated member is extended so that the protrusion is between or through wires of the filter, and the protrusion is engaged to or between two or more of the wires. The filter is placed within the tube or sheath, as by retracting the cable or elongated member to pull the filter, by moving the tube or sheath over the cable or elongated member while it engages the filter under tension, or both.
