Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a guide extension catheter. The guide extension catheter may include a proximal shaft having a first outer diameter. A distal sheath may be attached to the proximal shaft and may have a second outer diameter greater than the first outer diameter. A trackable tip member may be attached to the distal sheath and extending distally therefrom. The trackable tip member may define a guidewire lumen therein.

Abstract: Embodiments of the disclosure provide an ablative system for nerve modulation through wall of a blood vessel. The ablative catheter system includes an elongate member having a proximal end and a distal end, a number of electrode elements, an expansion mechanism. The electrode elements are finger-like structures mounted at their proximal ends for pivotal rotation radially outward from the longitudinal axis of the elongate member from a collapsed state. Each electrode element having inner and an outer surface with an electrode portion connected to a source of electrical energy and an insulated portion and a slope surface forming the proximal portion of the inner surface, sloping outward from the longitudinal axis of the elongate member, and a tip portion at the distal portion of the inner surface, angled toward the longitudinal axis of the elongate member. The electrode element inner surfaces in the collapsed state define a central cavity.

Abstract: Medical devices for nerve modulation through the wall of a blood vessel are disclosed. The medical device may include an elongate member having a proximal end and a distal end. A hollow ablation member may be disposed at the distal end of the elongate member and includes a number of electrodes positioned on its outer surface. The ablation member may be configured to shift between a collapsed position and an expanded position such that that a portion of the ablation member can be brought into contact with the wall of the blood vessel or placed adjacent to the wall of the blood vessel. The ablation member may also be retractable from the blood vessel treatment site.
