    Abstract: A needless connector is provided which utilizes a resealable preslit septum valve. The valve is resiliently restrained relative to a housing with the valve and housing configured to accept a standard male luer lock having a luer tip which penetrates the valve through the opening to extend within the housing and a luer locking flange of the luer lock extending about the housing. The valve includes a disk shaped upper portion covering the opening, a lower portion spaced from the housing and extending downward from the disk shaped portion into a passageway defined by the housing, and an annular skirt to attach the septum to the housing. The connector exhibits satisfactory leak pressure after multiple connections and disconnects to the luer lock fitting and long periods of indwell of the luer tip.

    Abstract: A polymer based composition for fabricating into articles is described. The composition comprises: a polypropylene in an amount by weight from 40-90% of the composition and having a melting temperature greater than 130 DEG C; a radio frequency susceptible polymer in an amount by weight from 5-50% of the composition and having a dielectric loss greater than 0.05 at 1-60 MHz and ambient temperature to 250 DEG C, the susceptible polymer being selected from (1) polymers containing at least one segment selected from the group consisting of urethanes, esters, ureas, imides, sulfones, and amides, and (2) ethylene copolymers having 50-85% ethylene content copolymerized with at least one monomer selected from the group consisting of acrylic acid, methacrylic acid, ester derivatives of acrylic acid with alcohols having 1-10 carbons, vinyl acetate, and vinyl alcohol; a compatibilizing polymer in an amount by weight from 5-30% of the composition, the compatibilizing polymer conferring compatibility between the radio frequency susceptible polymer, and the polypropylene, the compatibilizing polymer being a styrenic block copolymer with hydrocarbon soft segments, and wherein the composition has an optical haze value of less than 30% for the composition processed into a film of about 0.299 mm in thickness measured in accordance to ASTM D-1003, a mechanical modulus of less than 2758x10 Pa when measured according to ASTM D-882 and the composition exhibits no strain whitening after being strained at moderate speeds of about 50 cm per minute to about 100% elongation.

    Abstract: A steam sterilizable monolayer medical tubing comprising a blend of a melt strength enhancing agent of a homopolymer or copolymer of polypropylene having free-end long chain branches of propylene units, a melt flow index of greater than 10 and in an amount of 1-10% by weight and a second component selected from the group of (i) a selectively hydrogenated block copolymer of a vinyl aromatic hydrocarbon and a conjugated diene and (ii) a selectively hydrogenated block copolymer of a vinyl aromatic hydrocarbon and a conjugated diene to which has been grafted, an alpha, beta-olenfically unsaturated monocarboxylic or dicarboxylic acid reagent.
