A system for introducing a stent into a patient at a site of stenosis is disclosed. The system comprises a balloon catheter (10) having a stent (24) surrounding the balloon portion (20) of the catheter (10). At least one stent-retaining means is located adjacent to at least one end of the balloon (20) to retain the stent (24) in position on the catheter (10) until the balloon (20) is inflated. Upon inflation of the balloon (20), the stent (24) is expanded and the retention means releases the stent. The balloon (20) is then deflated and the catheter (10) is removed from the patient, leaving the expanded stent (24) in place. |
