Abstract:
A system/assembly for delivery and deployment of an expandable stent within a vessel, comprising:a catheter having proximal and distal ends and an inner shaft; a stent, 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 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, the expandable inflation means being a medical balloon; and a securement component coaxially mounted on the catheter within the medical balloon, the securement component designed and adapted to aid in maintaining the stent in position on the catheter during delivery to the deployment site while the stent is in its delivery diameter, the securement component being constructed and arranged for selectively providing at least one enlargeable mounting body within the medical balloon for receiving the stent, the enlargeable mounting body having an enlarged state and a collapsed state, a fluid is introduced into a space between the at least one enlargeable mounting body and the medical balloon to expand the stent to its deployment diameter independent from the at least one enlargeable mounting body.
