Abstract:
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.
