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:] [1.] A method for suturing a puncture site in a blood vessel wall at the end of a tissue tract, the blood vessel wall having a distal side and a proximal side, said method comprising:forming at least two penetrations in the blood vessel wall at the end of the tissue tract adjacent to the puncture site with at least one needle;passing a suture material through the two penetrations outwardly from the blood vessel wall to span the distal side of the puncture site; anddrawing the penetrations together with the suture material.
