Abstract: The present invention is directed to a cold cutting polypectomy snare. The cold cutting polypectomy snare has a cross section optimized for polypectomy. In some embodiments, the snare may have a uniform cross section along a length of the snare. In other embodiments, the snare may include a first side and a second side, wherein the first and second sides each have a unique cross section. Further, the cross-sections of the first side and the second side can be configured to couple together when a diameter of the snare is decreased to affect a cutting of a polyp.
