Expandable stent and delivery system

摘要

An expandable stent and delivery system (12), for enhancing luminal dilation of a blood vessel and treating aneurysms, includes proximal (32), intermediate (34) and distal (38) cylindrical members disposed on and spaced apart along an elongated core member (26) such that first (36) and second (40) gaps are formed. The expandable stent (10) includes anchor members (52) which align with the gaps. The expandable stent is mounted on the intermediate cylindrical member, and the anchor members are disposed within the gaps thereby locking the stent onto the core member.
