摘要： A method for manufacturing a stent includes forming a stent blank from a first material, the stent blank comprising a plurality of struts and a plurality of crowns, each crown connecting at least two struts, and a plurality of slots in at least some of the plurality of struts and/or the plurality of crowns, depositing a second material over outer surfaces of the struts and the crowns and in the slots to encase the stent blank in the second material, creating at least one opening through the second material, and removing the first material to form a stent comprising the second material, the stent having a continuous lumen from one end of the stent to the other end of the stent, the continuous lumen being partitioned in portions corresponding to the locations of the slots in the stent blank. The lumen may then be filled with a therapeutic substance.

摘要： A stent includes a bioabsorbable metal, a hydrothermal conversion film covering the bioabsorbable metal, and a coating covering the hydrothermal conversion film. A method for manufacturing a stent includes forming a stent body comprising a bioabsorbable metal, forming a hydrothermal conversion film over surfaces of the stent body, and coating the hydrothermal conversion film with an overcoat.

摘要： A catheter assembly includes a catheter comprising a flexible elongated member including a distal portion that includes a tubular body defining an inner lumen and a plurality of body apertures that extend through a sidewall of the tubular body into the inner lumen, and a plurality of primary electrodes positioned along the tubular body. The catheter assembly includes a wire defining at least one secondary electrode, the wire being configured to be slidably moved through the inner lumen of the tubular body, where the wire and the plurality of primary electrodes are configured to electrically couple to an energy source that delivers an electrical pulse to a fluid in contact with the plurality of primary electrodes and the at least one secondary electrode to cause the fluid to undergo cavitation to generate a pressure pulse wave within the fluid.
