Two stage light curable stent and delivery system
First Claim
Patent Images
1. A stent delivery system for implanting an expandable stent, the system comprising:
- an expandable stent formed with a tubular stent wall containing encapsulated light curable material, the stent wall adjacent to the material being transmissive to curing light for hardening the material;
a catheter assembly having a proximal end and a distal end;
the distal end having a mounting region for mounting of the stent and including an expandable member receivable in the stent to expand the stent to an expanded configuration while mounted on the mounting region; and
a material curing apparatus including at least one light emitter disposed about the expandable member and in light transmission relationship with the material while the stent is in the expanded configuration on the mounting region.
