Claim 1
Independent Claim
209 words
A device for securing a plurality of segments of suture together, said device comprising: a first rod having a distal end for insertion into the body and a proximal end, said first rod having a lumen extending from the distal end to the proximal end; a plurality of opposing grasping jaws mounted on the distal end of the insertion rod, said grasping jaws being operable from the proximal end of the insertion rod to open and close upon the segments of suture; a heating element on at least one of the grasping jaws, said heating element operable to apply heat to segments of suture; a snare having a distal end and a proximal end, and having a snaring structure capable of snaring a segment of suture, said snare being disposed within the lumen of the first rod, said snare rod extending proximally within the first rod and being operable from the proximal end of the first rod to slide longitudinally and rotate within the lumen of the first rod; said snare being extendable from the distal end of the first rod, and being retractable into the distal end of the first rod so that any suture segments ensnared in the snare are drawn into proximity of the grasping jaws.
