Abstract:
A method for producing a stent comprising:a) blending at least two bioresorbable, bio-compatible homo-polymers in a predetermined ratio to form a blend; b) producing a monofilament from said blend by an extrusion process, said monofilament having a diameter between approximately 0.145 mm and 0.6 mm; c) extruding the monofilaments to a draw ratio of between approximately 3.5 to 5.5; d) braiding the monofilaments into a substantially helical weave forming a tubular-shaped device; e) annealing said tubular-shaped device at a temperature between the glass transition temperature and melting temperature of the blended polymers for between approximately five minutes and 18 hours.
