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: Methods and devices for dilating a stricture of a body lumen are disclosed. In some embodiments, a device for dilating a lumen of a body comprises an elongate member having a proximal end and a distal end and an inflatable scaffold member disposed on the distal end of the elongate member, the inflatable scaffold member defining a lumen. In some additional embodiments, the device may further include an inflation member in fluid communication with the lumen of the inflatable scaffold member. Additionally, in some embodiments, the inflatable scaffold member is frangibly connected to the inflation member.
