1. An angioplasty device comprising:

  • a guide wire to be inserted into a blood vessel, anda flexible tubular body extending along a longitudinal axis between a proximal end and a distal end and having a proximal part, which includes the proximal end, and a distal part, which includes the distal end, the tubular body comprising;

    an inflatable balloon arranged radially about the tubular body in the distal part;

    a first leaktight internal conduit extending parallel to the longitudinal axis at least in the distal part, so as to permit the insertion of the guide wire into the first conduit and the sliding of the tubular body along the guide wire;

    at least a second internal conduit extending parallel to the longitudinal axis and opening out, on the one hand, at the proximal end and, on the other hand, into the balloon in such a way as to permit the injection of a fluid into the balloon;

    one or more injection orifices situated in the distal part; and

    a third internal conduit opening out, on the one hand, at the proximal end and, on the other hand, into the one or more injection orifices, in such a way as to permit the injection of a contrast agent through the one or more injection orifices when the guide wire is in the first conduit.
