A device for engaging tissue having a preexisting opening includes a generally annular-shaped ring having a width disposed about a longitudinal axis, and at least two staple members extending from the ring. Each of the at least two staple members have a thickness and at least a distal portion formed of an elastic material. The distal portions of the staple members have a first configuration, where the distal portions are separated by a first distance and wherein the distal portions are substantially parallel to the longitudinal axis, and a second configuration, where the distal portions are separated by a second distance, the second distance being less than the first distance, and the at least two staple members engage tissue surrounding the preexisting opening. The annular-shaped ring has a width that is greater than the thickness of the at least two staple members.
