Abstract
A catheter configured to carry one or more stents and having an inflatable balloon for expanding a stent surrounding the balloon. The catheter is characterized in having a positioner for moving the one or more stents relative to the balloon from a first position in which the stent does not surround the balloon to a second position in which the stent surrounds the balloon. Also disclosed is a method for deploying a stent at a desired location in the vascular system.
Claims11
A stent delivery system, comprising:
- a catheter having a distal end;
- an inflatable balloon near the distal end for expanding a stent surrounding the balloon;
- a plurality of stents carried upon the catheter;
- a separating mechanism carried upon the catheter, wherein a stent to be expanded is separated from an undeployed adjacent stent via the separating mechanism and wherein the separating mechanism is non-releasable from the distal end of the catheter;
- and
- a positioner which is longitudinally slidable along the catheter independently of the plurality of stents such that the positioner is configured to move the plurality of stents relative to the balloon from a first position to a second position in proximity to the distal end so that at least one of the plurality of stents surrounds the balloon.
