RADIOPAQUE MEDICAL BALLOON

摘要

A medical balloon (10) is made radiographic, such as by incorporating a radiopaque foil (36) or film layer (35). The radiopaque foil or film layer may be placed between an inner layer (30) and an outer layer (32) of a non-compliant balloon wall. The foil or film may provide the balloon with a radiographic quality from a first end to a second end in the absence of an inflation fluid. The balloon may be provided with the foil or film in a manner that provides a first section, such as the barrel (16), with a first radiographic quality, and a second section, such as the cone (18, 20), with a second radiographic quality. The film may also be applied as a decal or applique to the external surface of a balloon-shaped body. Related methods are also disclosed.
