An expandable stent and delivery system therefor is provided for treating vascular
diseases such as partially occluded blood vessels and aneurysms. The delivery system
includes proximal, intermediate and distal cylindrical members disposed about an
elongated core member. The proximal, intermediate, and distal cylindrical members
are spaced apart such that first and second gaps are formed. The expandable stent
includes anchor members which are formed by winding a radiopaque coil onto a threaded
portion of a strut member of the expandable stent. The expandable stent is mounted
on the intermediate cylindrical member with the anchor members disposed within
the gaps between the cylindrical members. A deployment catheter is used to compress
and constrain the stent about the intermediate cylindrical member to thereby interlock
the stent onto the core member.
