Classification: CPC A | IPC A

Claim 0:
1. A tissue ligation system comprising:
a catheter having a distal end, a proximal end, and a lumen extending longitudinally therethrough, the catheter having an outer diameter smaller than an inner diameter of a biopsy channel of an endoscope;
a cage comprising a plurality of circumferentially disposed struts and having a distal portion, a proximal portion, and a lumen extending therebetween, the proximal portion in communication with the distal end of the catheter;
a suture extending through the catheter lumen and having a distal end and a proximal end, the distal end comprising a distal suture loop releasably disposed on the plurality of circumferentially disposed struts at the distal portion of the cage,
a thread having a distal end tied to the proximal end of the suture at a frangible joint, the frangible joint proximal of the distal suture loop and distal of the proximal end of the catheter, wherein the force necessary to break the distal suture loop is greater than the force necessary to break the suture from the thread at the frangible joint; and
a telescoping tissue grasper extending longitudinally through the catheter lumen, the telescoping tissue grasper comprising a shaft having a plurality of fingers circumferentially disposed at a distal end thereof.
