Abstract
A stent delivery system includes an inner tubular member on which a stent is loaded, an outer jacket extending over said inner tubular member, the retraction of which causes deployment of the stent, and a handle adapted to move the jacket relative to the inner tubular member. The constructions of the inner tubular member and outer jacket and the handle provide increased control of the relative movement of the outer jacket relative to the inner tubular member, and prevention of premature release of the stent from the deployment instrument, and greater control over stent deployment among other advantages.

15. A stent deployment device comprising:
-
a catheter assembly having an inner tube and an outer tube, the outer tube being movable relative to said inner tube;
said inner tube having a distal end sized to receive a stent;
a drive mechanism connected to said catheter for moving said outer tube relative to said inner tube and to thereby expose said stent on said inner tube;
said drive mechanism including a one way lock such that said outer tube moves relative to said inner tube in only one direction. - View Dependent Claims (16, 17, 18)

19. A method of deploying a stent comprising:
-
providing a collection of deployment devices for a plurality of different sized stents;
each of said devices in said collection having a substantially identical outward appearance;
selecting at least one deployment device according to a first stent size wherein said deployment device has a drive mechanism tailored for said first stent size, said drive mechanism being different than a drive mechanism for another of said deployment devices;
deploying a stent having said first stent size with said selected deployment device into a patient. - View Dependent Claims (20)
