Patent ID: 8029532

Claim:
A closure device assembly comprising: a catheter having a hollow sheath and an open distal end; a pusher slidably disposed in the hollow sheath; a proximal bioremodelable patch and a distal bioremodelable patch co-disposed in the sheath, each patch having a plurality of perforations spaced apart from each other; and at least two joining elements; wherein one joining element extends through a first perforation of the first bioremodelable patch and through a first perforation of the second bioremodelable patch, and another joining element extends through a second perforation of the first bioremodelable patch and through a second perforation of the second bioremodelable patch; wherein the pusher is configured to sequentially dislodge the proximal and distal bioremodelable patches and the joining elements from the open distal end near the bodily opening, wherein the pusher comprises first and second displacement portions connected by a longitudinal core, the first displacement portion having a distal surface that engages a proximal surface of the proximal bioremodelable patch, and the second displacement portion having a distal surface that engages a proximal surface of the distal bioremodelable patch, and wherein the longitudinal core passes to one side of the proximal bioremodelable patch.
