A suture applying device comprises a shaft which carries a pair of needles near its distal end. The needles are joined by a length of suture, and the shaft is used to both introduce the needles into a lumen of a body structure and to push the needles back through tissue on either side of the puncture site. After the needles have passed through the tissue, they are captured on the shaft and drawn outward through the tract, leaving a loop of suture behind to close the puncture site near the body lumen. The suture can then be tied and the knot pushed back through the tract to complete the closure. Alternatively, a locking fastener formed of a resorbable material can be placed into the penetration over the sutures and the sutures tied over the fastener.

[ What is claimed is:] [1.] A suturing device comprising:a shaft having a proximal end and a distal end;a pair of needles removably carried near the distal end of the shaft;a length of suture secured to and extending between the needles;a sleeve received over the shaft; anda radially expandable structure disposed on the sleeve for presenting a receiving area to the needles as the shaft is drawn proximally relative to the sleeve, wherein the structure may be selectively expanded to capture the needles in the receiving area after they have passed through tissue.
