Abstract: A catheter balloon formed of a polymeric material such as expanded polytetrafluoroethylene (ePTFE) bonded to a second layer formed of a low tensile set polymer and/or impregnated with a low tensile set polymer. In a presently preferred embodiment, the low tensile set polymer is an elastomer selected from the group consisting of a silicone-polyurethane copolymer and a diene polymer. The low tensile set polymer has high strength, low modulus, high elongation, and low tensile set, to provide improved balloon performance. The diene or silicone-polyurethane has a low tensile set, which facilitates deflation of the balloon to a low profile deflated configuration. One aspect of the invention provides improved attachment of the diene to the ePTFE. In one embodiment, the second layer is formed of a diene mixed with a bonding promoter such as a vulcanizing agent which is covalently bonded to the diene.

Abstract: The present invention provides a new and useful nonstick coating for use on pure aluminum, alloys of aluminum, or aluminized steel surfaces. A nonstick coating according to the present invention includes a ceramic substrate disposed on an aluminum surface and a fluorocarbon polymer coating disposed on the ceramic substrate. The ceramic substrate, prior to firing, includes at least two layers: a first or bottom layer applied to the aluminum surface including an enamel ground coat; and a second or top layer applied over the enamel ground coat layer including a blend of one or more glass frits, non-ceramic refractory particles, and non-vitreous inorganic oxide particles. Upon firing, the ceramic substrate includes a continuous layer of vitreous enamel that is bonded to the aluminum surface. The exposed surface of the ceramic substrate has a micro-rough texture that is enriched with bonding sides for binder resins used in a fluorocarbon polymer primer layer. The ceramic substrate protects the aluminum surface from corrosion and mechanical damage and also protects the fluorocarbon polymer coating from abrasive wear.
