Abstract
A system for forming a purse string suture, including a suture applicator having a proximal handle, a length of suture wound on a spool, and a hollow suture needle extending from a distal end of the handle. The suture needle projects distally from the handle in a helical shape and terminates in a sharp distal tip with an opening in one side close to the distal tip. A free end of the length of suture may extend out of the distal tip and back into the hollow suture needle through the opening. The suture needle may have a deflection segment adjacent the distal tip that is more flexible than the rest of the helical distal portion of the suture needle. A linear hollow pivot shaft extends from a distal end of the handle substantially along an axis of the helical distal portion of the suture needle.
