Publication number: 20160166305Abstract: Cryotherapeutic systems with features that can facilitate pressure relief in the event of exhaust-passage blockage and associated devices, systems, and methods are disclosed herein. A cryotherapeutic system configured in accordance with a particular embodiment can include an elongated shaft having a distal portion and a pressure-relief portion proximal to the distal portion. The cryotherapeutic system can further include a supply lumen, an exhaust passage, and a balloon configured to receive refrigerant from the supply lumen and to exhaust refrigerant to the exhaust passage.

Publication number: 20150010422Abstract: Methods for manufacturing an endovascular stent having channel(s) formed therein for containing a therapeutic material. A molding and sintering process forms a thin-walled tubular component having a tubular core structure encapsulated therein. Portions of the thin-walled tubular component are removed to form at least a portion of the endovascular stent in a pattern corresponding to that of the tubular core structure such that the tubular core structure or corresponding channel(s) left thereby are captured within a wall of the formed stent. The tubular core structure is removed to leave a corresponding channel(s) in its stead. A plurality of holes is formed in the stent wall for filling the stent channel(s) with the therapeutic material and for eluting the therapeutic material therefrom.Type: ApplicationFiled: July 3, 2013Publication date: January 8, 2015Inventor: Stephen Nash
