Abstract:
An assembly for delivery and deployment of a stent within a vessel, comprising:a catheter having a proximal and distal ends; 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 balloon coaxially mounted on the catheter within the stent for expansion of the stent from the delivery diameter to the deployment diameter upon application of deployment pressure to the balloon; and an expandable tube component coaxially mounted on the catheter within the expandable balloon, wherein the expandable balloon and the expandable tube component are independently expandable relative to one another and wherein the expandable balloon is capable of being substantially collapsed when the expandable tube component is fully expanded.
