Abstract:
1. A method for delivering an expandable stent into a patient through a body lumen comprising: providing a flexible balloon catheter for delivering the stent, the catheter including an expandable balloon having a proximal end and a distal end, a control assembly and an outer sheath, the balloon secured to a distal end of the catheter, the balloon adjustable between a collapsed state and an expanded state, the control assembly for adjusting the balloon between states; mounting a stent on the balloon in the collapsed state, wherein a distal end of the sheath is positioned over the proximal end of the balloon, wherein the distal end of the sheath abuts a proximal end of the stent for limiting movement of the stent in at least the proximal direction relative to the catheter; inserting the flexible catheter and stent into a patient through a body lumen, while maintaining a fixed relative position between the stent and the catheter; activating the control assembly to expand the stent; advancing the sheath distally inside the stent and over the balloon prior to withdrawing the catheter; and withdrawing the balloon catheter after the stent has expanded.
