Abstract: Polypectomy devices and methods for making and using polypectomy devices are disclosed. An example polypectomy device may include an elongate sheath having a proximal end region and a distal end region. A shaft may be slidably disposed within the sheath. A handle may be coupled to the proximal end region of the sheath. The handle may be designed to axially shift the shaft relative to the sheath. A snare may be coupled to the shaft. The snare may include a first region, a traction region, and a distal tip region. The first region may have a non-circular cross-sectional shape. The traction region may include a plurality of traction members. At a position between two adjacent traction members the snare may have a reduced cross-sectional area relative to the first region. The distal tip region may have a circular cross-sectional shape.

Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a renal nerve modulation device. The renal nerve modulation device may include an elongate shaft having proximal region and a distal region. An ablation member may be coupled to the distal region. The distal region may have a distal inner diameter. The proximal region may have a proximal inner diameter that is smaller than the distal inner diameter. A ribbon may be disposed within the distal region of the shaft. The ribbon may have a proximal end and a distal end. The proximal end of the ribbon may extend into the proximal region of the shaft. The distal end of the ribbon may be disposed adjacent to or otherwise coupled to the ablation member.
