    摘要： A medical device that has a sliding or peeling surface coated with diamond-like carbon (DLC) coating. The coating reduces sliding or peeling resistance. The coated substrates may be polymeric. The coating may be applied from a cold plasma of a hydrocarbon gas such as acetylene. Plasmas may be generated to deposit the coating on interior surfaces, exterior surfaces, or both.

    摘要： A process for blowing a balloon from a tubular parison of a thermoplastic polymer material by radially expanding the parison at an elevated temperature and pressure, the process characterized in that: a) the polymer material includes a “H-bonding” polymer which undergoes interchain hydrogen bonding between at least some segments thereof; b) the parison is conditioned in a high moisture environment prior to blowing, and c) the balloon is blown after moisture conditioning of the parison and without an intervening drying thereof. H-bonding polymers may be polyamides, polyurethanes or block copolymers containing a polyamide or polyurethane block. The process reduces occurrence of fish eye defects in the formed balloons.

    摘要： Catheters, balloons, and methods of manufacturing balloons for balloon catheters using lasers are disclosed. A catheter with a shaft sized for use with a 0.014 inch guide wire includes a polymeric balloon having a body portion with an inflated outer diameter of more than 6 millimeters. An inflatable balloon includes an inflated outer diameter to inner waist diameter ratio of 12.5 to 1. An inflatable polymeric balloon that has a body portion with two regions that have different molecular orientations is also provided. A method of processing an elongate polymeric material includes heating a portion of the polymeric material with a laser while longitudinally stretching the portion of the polymeric material. A method of manufacturing a balloon includes heating and longitudinally stretching a first and second portion of an elongate polymeric tube to form first and second end portion. The remaining body portion is radially expanded to form the balloon.
