ABSTRACT:
A procedure for endoscopically removing a polyp utilizes an elongate tubular member having a cup-shaped web member at a distal end portion and an electrically conductive cauterization loop inserted through the tubular member. Upon insertion of an endoscope assembly into a patient, the distal end portion of the tubular member and the cauterization loop are ejected from the distal end of the biopsy channel of the endoscope assembly. Upon a subsequent opening of the cauterization loop, the cauterization loop is placed over a polyp to be removed, the web member is then opened and suction is applied through the tubular member to entrain the polyp to the web member. Electrical current is conducted to the cauterization loop to sever the polyp from the patient, and the loop is closed. The severed polyp is held in the web member by suction and is subsequently removed from the patient.
