Angioplasty device

An angioplasty device comprising:

• a 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:
• a multipurpose conduit extending parallel to the longitudinal axis and opening out at the proximal end, at the distal end, and into one or more injection orifices situated in the distal part, wherein the multipurpose conduit has a first diameter in an end part of the distal part, and has a second diameter greater than said first diameter from the proximal end to the end part of the distal part, such that a guide wire having an external diameter substantially equal to the first diameter can be inserted into the multipurpose conduit and the tubular body can slide along the guide wire, and injection of a contrast agent into a patient's through an injection orifice when the guide wire is in the multipurpose conduit;
• an inflatable angioplasty balloon positioned around the end part of the multipurpose conduit between the one or more injection orifices and the distal end, such that the tubular body has substantially the same diameter along an entire length thereof;
• an inflation conduit extending parallel to the longitudinal axis and opening out at the proximal end and into the angioplasty balloon, such that injection of a fluid into the angioplasty balloon inflates the angioplasty balloon, the inflation conduit being leaktight with respect to the multipurpose conduit.

• through one or more injection orifices when the guide wire is in the multipurpose conduit,
• an inflatable angioplasty balloon positioned around the tubular body in the distal part;

• an inflation conduit extending parallel to the longitudinal axis and opening out at the proximal end and into the angioplasty balloon, such that injection of a fluid into the angioplasty balloon inflates the angioplasty balloon, the inflation conduit being leaktight with respect to the multipurpose conduit.
