Balloon catheter with stent securement means

An assembly for delivery and deployment of an inflation expandable stent within a vessel, comprising:

• a catheter having proximal and distal ends and an inner shaft;
• an expandable balloon coaxially mounted on the catheter;
• a tube component coaxially mounted on the catheter axially within the expandable balloon, the tube component having a plurality of ribs and wherein the tube component is comprised of more than one corrugated tube;
• and
• 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, the expandable balloon being capable of expansion of the stent from the delivery diameter to the deployment diameter upon application of fluid deployment pressure to the balloon.
