Abstract
Polymeric composite stents reinforced with fibers for implantation into a bodily lumen are disclosed.
Claims20
A method of making a stent comprising:
- disposing a plurality of fibers within a mold for forming a structure;
- disposing a matrix polymer that is partially or completely molten into the mold to at least partially embed the fibers within the molten polymer, the fiber comprising a material having a melting temperature greater than a melting temperature of the matrix polymer, wherein a temperature of the matrix polymer and the fibers in the mold is less than the melting temperature of the fiber material;
- cooling the molten polymer to form the structure;
- and
- fabricating a stent from the cooled structure.

A method of making a stent comprising:
- disposing a plurality of fibers in an extruder for forming a structure;
- conveying a matrix polymer into the extruder, the fibers comprising a material having a melting temperature greater than a melting temperature of the matrix polymer;
- forming the structure with the extruder at a temperature greater than the melting temperature of the matrix polymer and less than the melting temperature of the material, wherein at least some of the fibers becoming embedded within the matrix polymer;
- and
- fabricating a stent from the cooled structure.
