A device for implanting a balloon-expandable vascular endoprosthesis. The device comprises a catheter (2) with one end having an inflatable balloon (33) which, when uninflated, receives an unexpanded endoprosthesis (6) between two spacers (17, 25) having a maximum intermediate diameter (d11, d12) between the outer diameter (d2) of the unexpanded endoprosthesis (6) and the inner diameter of the expanded endoprosthesis (6). The spacers (17, 25) have a gradually decreasing diameter on either side of their maximum diameter (d11, d12). The device is useful in angioplasty.
