Abstract
Methods for attaching an axial filament to the body of a self expanding stent, the filament serving to enhance the radial self expanding force of the stent body. Also stents having enhanced radial self expansion characteristics.
Claims39
A method of fabricating a self-expanding stent with enhanced radial expansion force, said method comprising the steps of:
- (1) providing a stent body in the shape of a tube;
- (2) providing at least one filament arranged axially to said stent, said filament being elastic;
- (3) attaching said filament to said stent body with an adhesive in a position such that said filament exerts an axial compression force on said stent body when said stent is axially elongated.
A method of fabricating a self-expanding stent with enhanced radial expansion force, said method comprising the steps of:
- (1) providing a self-expanding stent body in the shape of a tube, said stent body formed of a plurality of intersection threads;
- (2) covering at least a portion of said stent body with an adhesive dissolved in a solvent;
- and
- (3) heat treating said stent to evaporate said solvent;
- whereby said threads are stiffened.
A method of fabricating a self-expanding stent with enhanced radial expansion force, said method comprising the steps of:
- (1) providing a stent body in the shape of a tube;
- and
- (2) applying axial strips of adhesive to said stent body.
A self-expanding stent with enhanced radial expansion force comprising:
- a stent body in the shape of a tube;
- and
- at least one strip of adhesive running axially of said stent body and bonded to said stent body.
