Abstract
A one-piece fastener or staple includes a base that contacts tissue and a prong that extends through the tissue. A suture lead is anchored to the base and a needle is attached to the suture lead. A tool positions the fastener adjacent to the tissue, and is operated to drive the prong and the suture needle through the tissue. The tool includes a needle grabber that is operated to grab the needle and pull the needle out of the patient. Since the suture lead is attached to the fastener, a prosthesis can be placed on the suture lead and pushed down to the tissue. A cassette is releasably mounted on the tool and contains the fastener, the suture lead and the suture needle. Alternative forms of the anchor have sutures attached to a base at locations that are spaced apart from each other, and sutures associated with each of two adjacent anchors can be tied together or sutures associated with a single anchor can be tied together. A suture threadably connected to an anchor can be used as a running suture. A prosthetic device can have a running suture associated therewith that is threadably attached to each of a plurality of anchors. Another form of the system includes a running suture with …
