Abstract
A stent contracting apparatus configured with retractable grippers to engage the struts of a self-expanding stent to hold the stent in a collapsed position and to release the stent within a body lumen. The grippers of the stent contracting apparatus are moveable between a retracted and deployed position by an actuating mechanism which includes at least one control wire that extends outside the body lumen. A post-dilatation expandable member allows a physician to adjust the positioning of the expanded stent within the lumen if necessary.
