A device (100) for medically sealing a perivalvular leak associated with implanted valves includes a bioresorbable tissue infiltratable sheet (116) for insertion through a perivalvular leak. A filament (122) extending through the sheet (116) is also provided which when pulled causes the sheet (116) to gather around the filament (122) on either side of the perivalvular leak. The gathered position of the sheet (116) may be secured by a series of stops and/or use of a capping member (200).
