1. A method of treating a vessel in a human body comprising:
- passing a balloon catheter, which has a balloon, over an elongate stent carrying member, which has a stent attached thereto and serves as a guidewire for the balloon catheter, to a treatment site in a vessel in a human body such that said balloon is aligned with said treatment site; and
expanding said balloon while said balloon catheter is over said elongate stent carrying member with said balloon aligned with the treatment site to dilate the treatment site prior to deployment of said stent.

7. An angioplasty method comprising:
-
positioning an elongate stent carrying member with a self-expanding stent directly attached thereto at a location in a vessel, which has a lesion; passing a balloon catheter, which has a balloon, over said elongate stent carrying member prior to deploying said stent from said elongate stent carrying member wherein said elongate stent carrying member serves as a guidewire for said balloon catheter; aligning said balloon of said balloon catheter with the lesion; and expanding said balloon in performing the angioplasty. - View Dependent Claims (8, 9, 10)

11. A method for treating a lesion in a human body comprising:
-
positioning an elongate stent carrying member, which has a self-expanding stent attached thereto, at a location in a vessel with the stent near a lesion; passing a balloon catheter with an expandable balloon over said elongate stent carrying member, which serves as a guidewire for said balloon catheter, to the lesion prior to deploying said stent from said elongate stent carrying member and dilating the lesion with said balloon, which surrounds the elongate stent carrying member; moving said balloon catheter after at least partial deflation thereof to allow deployment of said self-expanding stent at the lesion, while maintaining said balloon catheter on said elongate stent carrying member; and deploying said self-expanding stent from said elongate stent carrying member at the dilated lesion wherein the stent assumes an at least partially expanded shape. - View Dependent Claims (12)

13. A method of treating a vessel in a human body comprising:
-
passing a balloon catheter, which has a balloon, over an elongate stent carrying member, which has a stent attached thereto and serves as a guidewire for the balloon catheter as the balloon is passed thereover, while advancing said balloon catheter toward a treatment site in a vessel in a human body prior to deploying the stent from said elongate stent carrying member; aligning said balloon with said treatment site prior to deploying the stent from said elongate stent carrying member; and subsequent to said aligning said balloon with said treatment site, expanding said balloon while said balloon catheter is over said elongate stent carrying member with said stent attached thereto and said balloon aligned with the treatment site to dilate the treatment site prior to deployment of said stent.
