Abstract: The invention relates to multi-layer medical balloons. In one aspect, a medical device includes an inflatable balloon. The inflatable balloon includes a first layer including a material having a first modulus of elasticity, and a second layer adjacent the first layer, the second layer including a material having a second modulus of elasticity that differs from the first modulus of elasticity by at least about 2,000 psi. A cutting element is carried by the balloon.

Abstract: An angioplasty balloon catheter and method of making and using the same. The balloon catheter may include a catheter shaft and a balloon coupled to the shaft. The balloon may include one or more cutting edges coupled thereto. The shaft may include one or more inflation lumens and a plurality of openings defined therein that are in fluid communication with the inflation lumen or lumens.

Abstract: A flame retardant composition is provided containing (a) an aromatic polycarbonate resin, (b) a rubber modified graft copolymer, (c) a vinyl aromatic-unsaturated nitrile rigid copolymer, (d) a phosphate and (e) a tetrafluoroethylene polymer. The compositions contain elevated rubber loadings and/or utilize low molecular weight polycarbonate and/or low molecular weight vinyl aromatic-vinyl cyanide rigid copolymer. The composition exhibits enhanced retention of izod impact properties upon exposure to heat and humidity. The compositions are useful for making pellets which are stored and/or shipped in hot humid conditions, and which are then utilized for making molded business machine housings.

Abstract: Thermoplastic resin compositions containing an aromatic polycarbonate resin and a surface modified titanium dioxide having a first coating and no further coatings are disclosed. The compositions may include a rubber modified graft copolymer comprising a discontinuous rubber phase dispersed in a continuous rigid thermoplastic phase, wherein at least a portion of the rigid thermoplastic phase is chemically grafted to the rubber phase; a rigid copolymer; a fluoropolymer; and/or a flame retarding amount of an organophosphorus flame retardant. Preferred titanium dioxide include first coating materials of polyols or polysiloxanes. The thermoplastic resin compositions exhibit improved resistance to streaking compared to such thermoplastic resin compositions which incorporate titanium dioxide having a first coating and at least one additional coating.

Abstract: A thermoplastic resin composition contains an aromatic carbonate resin, a rubber modified graft copolymer comprising a discontinuous rubber phase dispersed in a continuous rigid thermoplastic phase, wherein at least a portion of the rigid thermoplastic phase is chemically grafted to the rubber phase, wherein the rubber phase of the copolymer is made by an aqueous emulsion polymerization in the presence of a (C.sub.30 -C.sub.108)polyacid surfactant, and a flame retarding amount of an organophosphorus flame retardant.
