Abstract: A radiopaque, optically translucent thermoplastic polyurethane compound is disclosed. The use of nano-sized particles of barium sulfate optionally in combination with a minor amount of certain dispersion aids allows the barium sulfate to be sufficiently dispersed within the thermoplastic polyurethane to retain optical translucency according to a defined Haze Determination Test. Medical devices, needing both visual spectrum observation before and during in-vivo medical use and radiopacity monitoring during in-vivo medical use, benefit from this compound. Optionally, a surface enhancer can also be used.

Abstract: The present invention is drawn to a syndet soap bar that after the washing process leaves a residual deposit on a substrate that provides protection from ultraviolet radiation comprising (a) a non-emulsifying surfactant having an HLB greater than 15; (b) from greater than 10% to about 25% by weight red petrolatum; and (c) at least one surface-treated metal oxide sunscreen. Optionally, compositions of the present invention may also include (d) at least one wetting agent having a log P value of greater than about 4.0 and/or (e) an organic sunscreen having a log P value of greater than about 4.0.

Abstract: Improved articles having reduced thrombogenicity when in contact with blood products containing albumin and methods of their preparation and use are provided. The articles comprise at the surface of blood contact a water insoluble polymeric substrate material having covalently attached thereon aliphatic extension of 12 to 22 carbon atoms. When exposed to blood, the aliphatic chain extensions provide a hydrophobic binding site for albumin. The articles when implemented with whole blood or blood products selectively enhance albumin affinity binding to the exclusion of other blood components, and subsequently minimize thrombus formation as well as other biocompatibility parameters, such as foreign body immune responses.
