Abstract: A medical device is disclosed for delivering energy to a body lumen. The device includes an elongate member including a proximal portion and a distal portion adapted for insertion into a body lumen; and an energy delivery device disposed adjacent the distal portion of the elongate member, the energy delivery device including at least one elongate electrode arm, wherein the elongate electrode arm is configured to transition between a first configuration and a second configuration different than the first configuration. The at least one elongate electrode arm includes an active region configured to contact and deliver energy to the body lumen. When the elongate electrode arm is in the first configuration, at least a portion of the active region of the elongate electrode arm extends radially inward toward a longitudinal axis of the energy delivery device.

Abstract: A drainage stent delivery system including an elongate shaft of a medial device, a drainage catheter or stent, and an interference fit member for selectively coupling the drainage stent to the elongate shaft. The drainage stent is selectively coupled to a distal portion of the elongate shaft by an interference fit between the interference fit member and the drainage stent such that axial movement of the elongate shaft relative to the drainage stent moves the interference fit member from a first position in which the interference fit member is engaged with the drainage stent and forms an interference fit with the drainage stent to a second position in which the interference fit member is disengaged from the drainage stent.

Abstract: A drainage stent delivery system including an elongate shaft of a medial device, a drainage catheter or stent, and a locking mechanism for selectively coupling the drainage stent to the elongate shaft. The drainage stent is selectively coupled to a distal portion of the elongate shaft such that the proximal end of the stent is positioned proximal of the distal end of the elongate shaft. The locking mechanism includes an engaging feature of the elongate shaft which engages a portion of the stent such that the stent may be selectively coupled to the elongate shaft through rotational motion of the elongate shaft relative to the stent. In some instances, the engaging feature of the elongate shaft may be a tab which extends into an opening of the stent.

Abstract: Medical devices as well as methods for making and using medical devices are disclosed. An example medical device may include an elongate catheter shaft having a distal end. A tip member may be rotatably coupled to the distal end of the catheter shaft. The tip member may have a groove formed therein. The groove may extend along a portion of the circumference of the tip member. A control member may be coupled to the catheter shaft. The control member may be configured to engage the helical groove and rotate the tip member.

Abstract: A drainage stent delivery system including an elongate shaft of a medical device, a drainage catheter or stent, and an engagement member, such as a distensible member or a compressible member, for selectively coupling the stent to the elongate shaft. The engagement member is positioned between the inner surface of the stent and the outer surface of the elongate shaft and is elongatable from a first length to a second length by longitudinal movement generally parallel to the central longitudinal axis of the stent to release the stent. At the first length, the engagement member is engaged with the inner surface of the stent to secure the stent on the elongate shaft, and at the second length the engagement member is sufficiently disengaged from the inner surface of the stent to release the stent from the elongate shaft such that the elongate shaft may be withdrawn from the stent.
