A brand new device and a method to do arteriographies which allow simultaneous angioplasties by using a catheter and a balloon capable of copying the narrowed portion of the artery under study, providing the contrast required to view the artery via a contrasting medium which is circumscribed within the diagnosis balloon and which is not in relationship with the patient's tissue; therefor, the catheter has a diagnosis balloon which may be filled with the contrasting medium.
