ARTICULATING SUTURING DEVICE AND METHOD

摘要

Devices, systems, and methods for suturing of body lumens allow the suturing of vascular puncture sites located at the distal end of a percutaneous tissue tract. An elongated articulated foot (24) near a distal end of a shaft (12) is inserted through the penetration and actuated so that the foot extends along the lumenal axis. The foot carries suturing attachment cuffs (52), and needles (38) are advanced from the shaft through the vessel wall outside of the penetration and into engagement with the needle cuffs after the foot has been drawn proximally up against the endothelial surface of the blood vessel. The suture (34) may be provided with a bight (80) between first and second ends, the bight including one or more loops prearranged to define a pre-tied knot when one or more ends of the suture past therethrough.
