  • Patent number: 4983229
    Abstract: In the practice of the instant invention, a lubricating phosphate coating is applied to the surface of a ferrous-base metal article by contacting the surface with an aqueous acidic phosphate coating solution which contains an amount of hydroxylamine which is effective in increasing the rate at which the phosphate coating deposits from the solution. The resulting coated article is then subjected to cold deformation.In a preferred embodiment, the metal article is additionally contacted with a second lubricating compound after the phosphate coating is applied. In addition to phosphate the coating solutions employed preferably contain one or more of the following ions: zinc, manganese, nitrate, nickel, ferrous, ferric, copper, fluoride, or mixtures thereof.

  • Patent number: 4479795
    Abstract: The present invention relates to medical polymers and devices made therefrom, and is based on the discovery that certain carboxylate antimicrobial agents can be releasably incorporated into permeable polymers. The walls of medical devices such as catheters can be fashioned from such polymers. In use, the antimicrobial agent diffuses from the walls to the surface of the device to form an antimicrobial barrier on the surface of the device and a zone of microbial inhibition on tissue surfaces surrounding the device, thereby effectively supplementing the body's own natural microbial barriers where they have been compromised. The bacterial contamination-resistant carboxylate-plus-polymer compositions herein can be used in the manufacture of a wide variety of medical devices, especially urinary catheters, intravenous catheters, wound dressings, and the like.

  • Patent number: 4392848
    Abstract: At least part of an antimicrobial catheter for use in humans and lower animals comprises a permeable polymer. The polymer must be in contact with both the environment external to the catheter and with a liquid reservoir of antimicrobial agent flowing through the lumen of the catheter, said liquid reservoir comprising an aqueous solution containing at least a minimum lethal concentration of a straight-chain carboxylic acid or carboxylic acid salt having from 4 to 9 carbon atoms. In use, the antimicrobial agent diffuses from the liquid reservoir through the polymer and provides a zone of microbial inhibition around the external surface of the catheter. The invention thus prevents nosocomial infections resulting from the use of catheters by inhibiting microorganisms at and around the placement site of the catheter when the catheter is inserted into the body of a human or lower animal.
