Patent abstract

A closure device includes a bioremodelable patch and a joining element linking one or more bioremodelable patches to tissue portions adjacent to a bodily opening. The closure device may include a pair of bioremodelable patches linked by sutures and compressively joined to overlapping tissue portions adjacent to the opening. The closure device may be further contained within an assembly additionally including a catheter having a hollow sheath and a pusher. The pusher may be used to dislodge one or more bioremodelable patches from the catheter to facilitate stable closure of a bodily opening, such as a septal opening in a PFO.
