Abstract
An endoscopic cutting and retrieval instrument includes an elongate electrically conductive wire and an inner loop and an outer loop both connected to a distal end of the wire. The inner loop and the outer loop have a common proximal loop portion and different distal loop portions. The distal loop portion of the outer loop is longer than the distal loop portion of the inner loop so that the outer loop is larger than the inner loop. A net attached to the outer loop forms a retrieval basket for capturing severed polyps and other tissues masses.
