Abstract
An expandable stent including a light and water curable resin embedded in a stent wall wherein the wall is formed to be transmissive to light for curing the resin and transmissive to fluid for further curing of the resin. A catheter delivery system may be provided for in vivo delivery, expansion, rigidization, and installation of the stent into a body lumen.
Claims25
A stent for implanting in a body lumen, comprising:
- a tubular wall defining a flexible stent body compressible to a delivery configuration and expandable to an implanted configuration;
- the wall being formed with at least one chamber;
- a resin deposited in the chamber, the resin being responsive to light and fluid to cure to assume a rigid condition;
- the wall including at least one transmissive section formed to provide for transmission of light from the exterior of the wall to the resin;
- the wall including at least one porous section to provide for transmission of fluid to the resin.
A stent delivery system for implanting 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, the system comprising:
- a catheter assembly with 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 fiber;
- the at least one fiber terminating distally in a diagonal cut defining a light emitter;
- and
- the emitter to be disposed in light exchange relationship with the material while the stent is in the expanded configuration on the mounting region.
