Abstract:

Balloons for use on medical devices such as catheter balloons are formed from polymer blend products which include a liquid crystal polymer (LCP), a crystallizable thermoplastic polymer, especially thermoplastic polyesters such as PET, and a compatabilizer. The compatabilizer may be an ethylene-maleic anhydride copolymer, an ethylene-methyl acrylate copolymer, an ethylene-methyl acrylate copolymer, an ethylene-methyl acrylate-maleic anhydride terpolymer, an ethylene-methyl-methacrylic acid terpolymer, an acrylic rubber, an ethylene-ethyl acrylate-glycidyl methacrylate terpolymer or a mixture of two or more such polymers.

International Classification:

B29C 49/64

US Classification:

425526, 425392, 425470, 249 79

Abstract:

A mold for a medical device balloon has a cavity adapted to receive a hollow parison expandable therein to form the balloon. The cavity has a cone region and a body region. The cone region is heated to a higher temperature, or the mold wall is formed to deliver applied heat more efficiently to the cone region, relative to the body region of the mold.

Appl. No.:

09/901352

Inventors:

Wayne Mareiro - Pepperell MN, US
Robert Estes - Danvers MA, US
Ralph Barry - Hudson MA, US

International Classification:

A61M029/00

US Classification:

604/103060

Abstract:

A medical balloon is constructed with protrusions thereon to prevent unwanted movement of an expandable, implantable medical device such as a stent during delivery and deployment. At least some of the protrusions are underlying the expandable, implantable medical device to grip the expandable, implantable medical device.

International Classification:

B32B 38/08
A61L 33/00

US Classification:

156280, 427 228

Abstract:

A medical device consists of a stent having a first surface and a second surface parallel to the first surface; a single expanded polytetrafluoroethylene (ePTFE) layer contacting the first surface of the stent; and an elastomeric layer applied to at least one surface of the stent. In at least one embodiment, the elastomeric layer is silicone. In at least one embodiment, the medical device is manufactured by positioning the ePTFE layer such that a first surface of the ePTFE layer contacts a first surface of the stent to form a stent-ePTFE assembly; and applying an elastomeric solution to the first surface of the ePTFE layer and at least one surface of the stent.
