Articulating suturing device and method
First Claim
1. A method for suturing a puncture in a tissue, the method, comprising:
- providing a device that includes a suture having a first end and a pre-tied knot spaced from said first end, the pre-tied knot being disposed about a first needle of the device at a point spaced back from the distal end of the device;
advancing said first end of said suture through the tissue using a second needle;
advancing said first end of said suture through said pre-tied knot using said first needle following advancing said first end of said suture through the tissue using the second needle; and
tensioning said suture across said puncture formed in said tissue, wherein said first needle is provided with a distal tissue penetrating tip, and wherein advancing said first end of said suture through said pre-tied knot includes pulling said suture with said distal tissue penetrating tip of said first needle.

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 The cuffs lockingly engage the needles and can be withdrawn proximally along the needle paths and through the tissue tract so as to form a loop of suture across the puncture. The articulating foot may be realigned with the shaft and withdrawn proximally through the tissue tract without dilating the tissue tract.

4. A method for suturing a puncture in a tissue using a device, the method comprising:
-
inserting at least a portion of a suture through a tissue tract of a patient body and through the tissue using a second needle; inserting at least a portion of a first needle through the tissue tract; advancing a first end of the suture with said first needle through a pre-tied knot of the suture following inserting said first needle through the tissue tract, the pre-tied knot being disposed about the first needle of the device at a point spaced back from the distal end of the device; and tensioning the first end of the suture and a second end of the suture adjacent the pre-tied knot to form a knot affixing a loop of suture across the puncture. - View Dependent Claims (5, 6)

7. A method for closing an opening in tissue using a suturing device, the method comprising:
-
inserting at least a portion of a suture through a tissue tract and through a tissue wall using a second needle; advancing a first end of the suture with a first needle through a pre-tied knot of the suture following inserting the at least a portion of the suture, the second needle, and the first needle through the tissue wall, the pre-tied knot being initially disposed about the first needle of the suturing device; and tensioning the first end of the suture and a second end of the suture adjacent the pre-tied knot to form a knot affixing a loop of the suture across the opening. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
