Method for manufacturing a stent and stent manufactured thereby

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.

1. A method for manufacturing a stent, the method comprising:
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; forming a plurality of slots into at least some of the plurality of struts and/or the plurality of crowns, such that the plurality of slots extend through the first material to create openings through the 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 through the slots to encase the stent blank in the second material; creating an opening through the second material; and removing the first material to form a stent comprising a plurality of struts and crowns defined by the second material, a continuous lumen is defined by the plurality of struts and crowns of the second material, the continuous lumen being partitioned in portions corresponding to the locations of the slots in the stent blank.
