The present invention is directed to a balloon for an intracorporeal catheter having at least a portion of its walls having radiopaque properties. The balloon is formed of a polymeric material, which has a single wall thickness of at about 0.001 inches to about 0.0125 inches while deflated. The radiopaque portion of the balloon has a thickness of about 0.00025 inches to about 0.012 inches, specifically about 0.002 inches to about 0.003 inches. The balloon is constructed of layers. The radiopaque material may be embedded within the film or deposited on the film to create radiopaque properties.
