Vessel access and closure device
First Claim
1. A method, comprising:
- positioning a distal end of a blood vessel access and closure device against a wall of a blood vessel in a patient;
advancing a distal end of a helical suture needle from the blood vessel access and closure device along a helical path that passes through the wall of the blood vessel, the suture having a distal end releasably attached near the distal end of the helical suture needle;
retracting the distal end of the helical suture needle into the blood vessel access and closure device along the helical path, leaving the suture in a helical suture coil that passes into the wall of the blood vessel;
creating an access opening through the wall of the blood vessel within an area of the wall bounded by the helical suture coil; and
tightening the helical suture coil to close the access opening in the wall of the blood vessel.

Abstract
A vessel access and closure device places a running suture in the wall of a blood vessel using a rotating helical suture needle that carries the suture along a helical path passing through the vessel wall, then reverses rotation to release a suture anchor attached to the distal end of the suture. A loose helical coil of suture is left behind as the helical suture needle withdraws. The device is withdrawn and replaced with a vessel dilator and an introducer sheath that opens up a larger access opening into the blood vessel and creates a pathway that passes though the helical coil of suture for introducing an interventional device into the blood vessel. After the interventional procedure is completed, the interventional device and the introducer sheath are withdrawn and the running suture is tightened and secured with a suture lock to close the access opening into the vessel.
