Abstract

A tissue removal tool for use with an endoscope. The tool includes a loop formed by a piece of wire. The loop is movable between an open position and a closed position. The shape of the loop is defined in the open position by a proximal portion and a distal portion. The piece of wire may have a cross-sectional height in the proximal portion unequal to a cross-sectional height in the distal portion.
