The present invention is a stent delivery system including a catheter, wherein the catheter includes an inflatable region. An expandable stent is disposed about at least a portion of the inflatable region. A first end of the at least one stent retaining sleeve covers an end of the stent prior to the stent being expanded for delivery. A second end of the at least one sleeve is engaged to at least a portion of the catheter adjacent to the inflatable region. The at least one stent retaining sleeve is constructed and arranged to longitudinally foreshorten from a first predetermined length to a second predetermined length when the stent is expanded for delivery. The second predetermined length being more than 5 percent shorter than the first predetermined length. When the stent is expanded for delivery, the at least one stent retaining sleeve is retracted off of the stent thereby releasing the stent from the catheter.
