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.
Claims10
A stent comprising a hydroxyapatite fiber, the hydroxyapatite fiber comprising:
- biodegradable polymer filaments coaxially aligned along a length of the hydroxyapatite fiber;
- and
- hydroxyapatite particles bound to the biodegradable polymer filaments.
A system for treating a vascular condition comprising:
- a catheter;
- and
- a stent disposed on the catheter;
- wherein the stent comprises a hydroxyapatite fiber, the hydroxyapatite fiber comprising:
- biodegradable polymer filaments coaxially aligned along a length of the hydroxyapatite fiber;
- and
- hydroxyapatite particles bound to the biodegradable polymer filaments.
