Abstract: An embodiment of the invention is directed to a medical instrument that includes a flexible elongate member and a distal assembly. The distal assembly is coupled to a distal end of the elongate member. The distal assembly includes a blunt member and a cutting tool pivotably attached to the blunt member. The blunt member is configured for insertion into a tissue layer. The cutting tool is arranged relative to the blunt member so that the cutting tool does not cut tissue as the blunt member is inserted into the tissue layer.

Abstract: Medical devices are disclosed including polypectomy snare devices. An example polypectomy snare device may include an elongated sheath having a distal end. A hollow shaft may extend through and be movable relative to the sheath. A distal portion of the shaft may have a slit formed therein. The shaft may be shiftable between a first configuration wherein the distal portion is substantially straight and a second configuration wherein the distal portion includes a bend. A snare wire may be disposed within the shaft. A distal section of the snare wire may extend through the slit when the shaft is in the second configuration.
