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 The device is withdrawn and replaced with a vessel dilator and an introducer sheath that opens up a larger access opening into the blood vessel and creates a pathway that passes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 After the interventional procedure is completed, the interventional device and the introducer sheath are withdrawn and the running suture is tightened and secured with a suture lock to close the access opening into the vessel.
