METHOD AND DEVICE TO DO ARTERIOGRAPHIES AND ANGIOGRAPHIES WITH A BALLOON WITHOUT INJECTING CONTRAST MEDIA IN THE VESSEL LUMEN

摘要

A device for arteriographies and angiographies includes a catheter having an inflatable, elastimeric, and soft diagnosis balloon, which may be inflated with a contrast media, with the diagnosis balloon having an inflated shape which copies, but does not deform, the inner surface of a narrowed portion of an artery. The narrowed portion of the artery may be angiographed or arteriographed while the diagnosis balloon is inflated and copies the inner surface of the narrowed portion of the artery.
