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: A medical device may include an insertion device having a proximal end, a distal end, and a lumen extending therethrough. A snare device may be configured to transition between a retracted state within the lumen of the insertion device, and an extended state extending distally of the insertion device. The snare device may comprise a wire. A member may be disposed within the lumen of the insertion device. The member may be configured to maintain legs of the snare device in an open snare loop configuration in the extended state. In the open snare loop configuration, the wire may include an arcuate loop.

Abstract: An endoprosthesis includes a stent having an inner surface defining a lumen and an outer surface; and a polymeric cover on the outer surface of the stent. The polymeric cover includes a base and adhesion elements. When the endoprosthesis is expanded to the expanded state in a lumen defined by a vessel wall, the adhesion elements create an interlock between the vessel wall and the endoprosthesis.

Abstract: A catheter adapted to measure a contact force. The catheter includes a proximal segment, a distal segment, and a spring segment. The spring segment extends from the proximal segment to the distal segment. The spring segment is configured to permit relative movement between the distal segment and the proximal segment in response to an application of the force on the distal segment. The spring segment includes a slotted tube having a longitudinal axis and a plurality of sensing elements. The sensing elements are disposed on surfaces of the slotted tube. The sensing elements are configured to output a plurality of signals indicative of the relative movement between the proximal segment and the distal segment.

Abstract: An open-irrigated ablation catheter system includes a catheter body, and an electrode tip body mounted on a distal portion of the catheter body. The electrode tip body includes a proximal end configured for connection to the catheter body and a wall defining an open interior region and including one or more irrigation ports. The wall is conductive for delivering radio frequency (RF) energy. The catheter system further includes a proximal insert positioned partially within the catheter body and at least partially within the proximal end of the electrode tip body. The proximal insert includes a fluid inlet for receiving a cooling fluid delivered via the catheter body. The proximal insert forms a flow path configured to direct the cooling fluid from the fluid inlet to cool the distal portion of the catheter body and to cool a junction of the catheter body and the electrode tip body.
