Abstract
A method for manufacturing a stent includes heating a plurality of wire strands to impart a desired shape to the wire strands, coating each wire strand with a biocompatible polymer in an extruder to produce a plurality of coated wire strands, and interlacing the coated wire strands to form a stent.
Claims20
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.
