Abstract
A delivery system for procuring implantation of an expandable stent in a bodily lumen of interest is disclosed including a fluid-operated moving cylinder sleeve means for retaining the stent in place during delivery retracting to release a stent at the implantation site.
Claims16
A delivery system for implanting an expandable stent in a bodily lumen of interest comprising:
- (a) an elongate flexible catheter having distal and proximal ends;
- (b) at least one fluid-operated, generally cylindrical tubular sleeve for placement over and retention of a stent in a delivery configuration prior to release, said sleeve being axially adjustable relative to said catheter and said stent and having a closed end and an open end for release of a contained stent;
- (c) an expandable stent having a proximal and distal end and being collapsible about said catheter to a delivery configuration of reduced diameter along the length thereof;
- (d) fluid supply system for supplying infusing fluid into said sleeve;
- and
- (e) integral fluid driven operating mechanism for axially adjusting said sleeve along said catheter.

A method of deploying an expandable stent in a bodily lumen of interest for procuring implantation of the stent comprising the steps of:
- a. providing an elongate flexible vascular catheter having distal and proximal ends;
- a stent in a delivery configuration of reduced diameter on said flexible catheter near the distal end thereof;
- and a fluid-operated, generally cylindrical tubular sleeve over the mounted stent, said sleeve providing retention of said stent in said delivery configuration and having an internal operator operable to axially adjust said sleeve relative to the catheter to release said stent;
- b. intraluminally disposing said catheter to place said stent at a deployment site of interest;
- and
- c. infusing fluid into said internal operator in said sleeve to retract said sleeve axially in a direction to release said stent in situ.
