Abstract
Abstract Suture devices, primarily for use in endoscopic surgery, include a suture needle made of bioabsorbable material for pulling a length of suture material through bodily tissue allowing the suture needle to be inadvertently or intentionally left in the tissue, and a suture needle having a length of suture material attached thereto with a contractible loop or passage at the proximal end of the suture material to allow the suture needle to be passed therethrough, the loop or passage contracting to clamp or grip the suture material to function similar to a conventional tied suture knot.
