Abstract
The wire loop of a surgical snare is constructed so as to include a weakened or frangible region. When it is desired to open the loop so as to move it from its entrapped position on a polyp, an additional force is exerted on the loop to draw it further into the sheath. This causes the frangible region to break, thereby opening the loop and permitting the wire to slide free of the polyp. In accordance with an alternate embodiment, the wire loop is constructed so as to fold back on itself, with the folded back end being captured by a retaining element inside the sheath. When the loop becomes entrapped on a polyp, it is extended out of the sheath somewhat further than during normal use, at which point the captured end of the loop is released, opening the loop and permitting its removal from within the patient.
