Abstract
A catheter system for removably securing a stent which generally includes an inner tubular member and an outer tubular member with an expandable member disposed about the inner tubular member. A foamed cover is disposed between the expandable member and the inner tubular member. An expandable stent is crimped onto the expandable member and is retained in place by compressing the foamed cover. Used with a stent delivery system, the catheter system is inserted into a body lumen such as an artery. The stent is secured in place while advancing the system through tortuous body lumen passages. The stent is advanced to the desired location in the body lumen and implanted by inflating the expandable member and thereby expanding the stent into the body lumen. The stent is released from the system by deflating the expandable member and withdrawing the catheter system from the body.
