    • The present invention relates to coating a porous, hydrophobic polymer with a hemocompatible coating and to the materials produced thereby. One embodiment of the present invention relates to the coating of expanded poly(tetrafluoroethylene) with one or more complexes of heparin, typically containing heparin in combination with a hydrophobic counter ion. The hemocompatible coating is dissolved in a mixture of solvents in which a first solvent wets the polymer to be coated and the second solvent enhances the solubility of the hemocompatible coating material in the solvent mixture. Typical first solvents wetting hydrophobic polymers include non-polar such as hydrocholorofluorocarbons. Typical second solvents include polar solvents such as organic alcohols and ketones. Azeotropic mixtures of the second solvent in the first solvent are used in some embodiments of the present invention although second solvents may be employed in a range of concentration ranges from less than 0.1% up to saturation. An example is provided of coating heparin complex onto an endoluminal stent, typically consisting of coating DURAFLO onto an ePTFE stent covering material.
    • 本发明涉及用具有血液相容性涂层的多孔疏水性聚合物以及由此制备的材料。 本发明的一个实施方案涉及用一种或多种肝素复合物涂覆膨胀的聚(四氟乙烯),其通常含有与疏水性抗衡离子组合的肝素。 将血液相容性涂层溶解在其中第一溶剂润湿待涂覆的聚合物的溶剂混合物中,并且第二溶剂增强溶血混溶物中血液相容性涂料的溶解度。 典型的第一溶剂润湿疏水性聚合物包括非极性如氢氯氟烃。 典型的第二溶剂包括极性溶剂如有机醇和酮。 在本发明的一些实施方案中使用第一溶剂中的第二溶剂的共沸混合物,尽管可以在小于0.1%至饱和的浓度范围内使用第二溶剂。 提供了将肝素复合物涂覆在腔内支架上的实例,通常由将DURAFLO涂覆在ePTFE支架覆盖材料上。

    • A system and method maximize profits by determining the optimal combination of sale price for a product and bids for advertising. The system and method address the non-linear relationship between product pricing and advertising through an advertising bidding system. In particular, a seller sells a product at a plurality of sale prices and buys the at least one advertisement by submitting a plurality of bid prices to the at least one advertising venue, resulting in a combination of bid prices for the at least one advertisement at each of the plurality of sale prices. Data from advertising with each of the at least one advertisement is collected. Then, a non-linear model for pricing and bidding is determined from the collected data, and an optimal price for the product and an optimal advertising bid for each of the at least one advertisement is determined from the non-linear model.
