Articulating suturing device and method
First Claim
1. A suturing device for suturing an incision, the suturing device comprising:
- a first penetrator configured to form a first penetration about a periphery of the incision, the first penetrator having a pre-tied knot disposed thereabout; and
a second penetrator configured to form a second penetration about the periphery of the incision, the second penetrator including suture disposed thereon such that during retraction of the first penetrator from the first penetration and the second penetrator from the second penetration, the first penetrator draws the suture through the first penetration via a link between the first penetrator and the suture such that the suture advances the pre-tied knot to suture the incision.

Abstract
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 near a distal end of a shaft is inserted through the penetration and actuated so that the foot extends along the lumenal axis. The foot carries suturing attachment cuffs, and needles 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 cross-section of the shaft within the tissue tract can be minimized by laterally deflecting the needles as they leave the shaft, while tapered depressions within the foot can guide the advancing needles into engagement with the cuffs. The cuffs lockingly engage the needles and can be withdrawn proximally along the needle paths and through the tissue tract so as to form a loop of suture across the puncture. The articulating foot may be realigned with the shaft and withdrawn proximally through the tissue tract without dilating the tissue tract.
