Method for manufacturing a wire stent coated with a biocompatible fluoropolymer
First Claim
Patent Images
1. A method for making a stent comprising:
- heat treating a plurality of wire strands;
coating the wire strands with a biocompatible fluoropolymer in an extruder to produce a plurality of coated wire strands;
spooling the coated wire strands; and
interlacing the coated wire strands from separate spools into a tightly held together monolayer integrated tubular shape, the tubular shape adapted to have axial and radial compressibility for insertion into a cardiovascular, vascular or non-vascular system of a human body.
