Abstract
A system for treating a vascular condition includes a stent including hydroxyapatite fibers interwoven to define a stent lumen. Another aspect of the invention is a method of manufacturing a stent by forming hydroxyapatite fibers and biodegradable polymeric fibers, and interweaving the fibers to form a stent wall. The hydroxyapatite fibers can be formed by a sol-gel process, followed by spinning of the gel to form the hydroxyapatite fibers.
Claims22

(canceled)
The stent of claim 7 wherein the biodegradable polymer is poly(lactide-co-glycolide) copolymer.
(canceled)
A system for treating a vascular condition comprising:
- a catheter;
- and
- a stent disposed on the catheter;
- wherein the stent comprises hydroxyapatite fibers and biodegradable polymeric fibers, the hydroxyapatite fibers and biodegradable polymeric fibers being interwoven to define a stent lumen.
(canceled)
The system of claim 16 wherein the biodegradable polymer is poly(lactide-co-glycolide) copolymer.
(canceled)
A method of manufacturing a stent comprising:
- forming hydroxyapatite fibers;
- forming biodegradable polymeric fibers;
- and
- interweaving the hydroxyapatite fibers with the biodegradable polymeric fibers to define a stent lumen.
A stent comprising a plurality of hydroxyapatite fibers made solely of hydroxyapatite, the plurality of hydroxyapatite fibers being interwoven to define a stent lumen.
