Stent delivery system having stent securement apparatus
First Claim
1. A system/assembly for delivery and deployment of an inflation expandable stent within a vessel, comprising:
- a catheter having proximal and distal ends;
a stent, inflation expandable from a delivery diameter to a deployment diameter, such that the delivery diameter is reduced from the deployment diameter for conforming the stent to the catheter, such that the stent, in its delivery diameter, is coaxially mounted on the catheter near the catheter distal end;
an expandable inflation means coaxially mounted on the catheter axially within the stent, for expansion of the stent from the delivery diameter to the deployment diameter upon application of fluid deployment pressure to the inflation means; and
a securement component coaxially mounted on the catheter, axially within the expandable inflation means, the securement component designed and adapted to provide a securement pressure to the stent in the delivery diameter to maintain the stent in position on the catheter during delivery to the deployment site.

26. A method of changing the profile of a balloon catheter for improving the mounting of a stent thereon and providing a catheter for multiple use, comprising the steps of:
-
providing a balloon catheter of relatively low profile adapted and rearranged for use in an angioplasty procedure;
sliding a stent mounting body to a position associated with the balloon to a position for receiving a stent and enlarging the catheter profile at that position, and mounting a stent on the balloon and mounting body at that position.

-
27. In a balloon catheter apparatus, the method of enlarging the catheter profile for facilitating the mounting of a stent thereon, comprising:
selectively providing an enlarged mounting body within the balloon in a position to receive a stent. - View Dependent Claims (23, 28, 29, 30)

31. The assembly of claim, the inflatable means being an expandable balloon coaxially mounted on the catheter axially within the stent, for expansion of the stent from the delivery diameter to the deployment diameter upon application of fluid deployment pressure to the balloon;
- and the securement component being an expandable tube component coaxially mounted on the catheter, axially within the expandable balloon, the tube component designed and adapted for fluid expansion to provide a securement pressure to the stent in the delivery diameter to maintain the stent in position on the catheter during delivery to the deployment site.
