Abstract:
An assembly for delivery and deployment of an inflation expandable stent, comprising:a catheter having proximal and distal end portions; an annular collar coaxially located at the catheter distal end portion; an expandable balloon coaxially mounted over the collar at the catheter distal end portion, the balloon being expandable from a contracted to an expanded state; a stent having proximal and distal end portions coaxially mounted on the balloon, the stent being expandable from a reduced to an enlarged condition, the reduced condition conforming the stent to the balloon and catheter, the stent having at least a proximal or distal end portion overlying the balloon, the collar abutting the stent as a stop; a cup coaxially mounted on the catheter distal end portion, the cup having a first end portion restraining the stent proximal end portion and being rigid; and the cup and collar cooperatively constructed and arranged to retain the stent distal and proximal end portions on the catheter in the stent reduced condition when the balloon is in the contracted state, the balloon and catheter cooperatively constructed and arranged to cause expansion of the balloon from the contracted to the expanded state and to release the stent proximal end portion from the cup end portion.
