Abstract

An apparatus for ligating a medical protrusion comprises a ligating suture having a proximal end and a distal end configured to circumscribe the medical protrusion, and a one-way lock positioned there between. The apparatus further comprises an endoscope, a cutter blade configured to cut the suture, and a device for ligating a medical protrusion. The device comprises a tubular body having a proximal end and a distal end, a handle positioned at the proximal end, an endoscope controller operably connectable to the endoscope, a cutting controller operably connectable to the cutter blade, a suture controller configured to be operatively coupled with the suture, a curved bridge positioned at the distal end, the bridge having a proximal end and a distal end, and an armature, having a proximal end and a distal end, configured to releaseably retain at least a portion of the suture.

Dependent claims

A device for ligating a medical protrusion, the device comprising:

a) a tubular body having a proximal end and a distal end;
b) a handle positioned at the proximal end of the tubular body;
c) a suture controller configured to be operatively coupled with a ligating suture;
d) an armature connected to the distal end of the tubular body and configured to releasably retain at least a portion of the ligating suture, said armature having a balloon shaped loop;
and
e) an armature controller operably connected to the armature through a controller wire, and configured to permit a user to manipulate an angular position of the armature about a rotational axis perpendicular to the tubular body to permit positioning of the balloon shaped loop and placement of at least a portion of the ligating suture about the medical protrusion, wherein the device further comprises a curved bridge positioned at the distal end of the tubular body, said bridge having a proximal end connected with the distal end of the tubular body and a distal end connected to the proximal end of the armature.
