Patent number: 11980728Abstract: A radiopaque balloon with a composite wall having a radiopaque adhesive affixing inner and outer layers of the balloon. The radiopaque adhesive provides a radiographic image of the balloon wall with or without the use of radiopaque contract media to inflate the balloon. A radiographically fainter image is provided as the balloon is inflated with well-defined edges of a balloon image, and the total radiopacity of the balloon does not change as the balloon is inflated. Also, a method of imaging a balloon wall and a method of imaging a radiopaque adhesive between two layers of a balloon wall are provided.Type: GrantFiled: September 22, 2020Date of Patent: May 14, 2024Assignee: C.R. Bard, Inc.Inventor: Richard K. Elton

Publication number: 20180344992Abstract: 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.Type: ApplicationFiled: November 10, 2017Publication date: December 6, 2018Inventors: Richard K. ELTON, Corey E. STAPLETON

Patent number: 5066881Abstract: A semi-conducting pyrolyzed glass fiber layer equalizes the electrical potential on the exterior surface of an insulated conductor when the layer covers the surface. The layer prohibits the development of a corona discharge and bleeds off any electrical charge developed thereon when the layer is electrically coupled to a body having a known potential. The insulated conductor may be windings in a dynamoelectric machine.Type: GrantFiled: July 23, 1990Date of Patent: November 19, 1991Assignee: General Electric CompanyInventors: Richard K. Elton, William R. Schultz, Jr.
