  • Patent number: 6596267
    Abstract: The invention discloses materials that adsorb readily to the surfaces of body tissues in situ and provide a steric barrier between such tissues, so that tissue adhesions, which typically form following surgical procedures, are minimized. These materials contain a polymer of hydrophilic molecules such as polyethylene glycol (PEG) bound to a polymer that spontaneously adsorbs to biological tissue such as phenylboronic acid (PBA). The PEG-PBA co-polymer can be formed in a variety of geometries. The materials can also be used to coat prosthetics and other implants.

  • Patent number: 6592768
    Abstract: The invention provided relates to the use of polyvinylpyrrolidone-iodine complexes in combination with gelling agents to produce strong disinfectants which not only physically stabilize biohazardous and infectious wastes but also kill pathogens contained in the wastes. The gelling agents include polyacyrlates that are superabsorbents.

  • Patent number: 6589550
    Abstract: A method for producing an intraocular lens, comprising the steps of injecting a high-refractive index, low viscosity composition of crosslinkable units into an enclosure and initiating polymerization under pressure to create a synthetic polymer lens. The method is especially suitable for producing an intraocular lens directly in the capsular bag of the eye from an injected aqueous solution of macromolecular particles, which can undergo a crosslinking reaction to a solid lens when exposed to light.

  • Patent number: 6566406
    Abstract: Biocompatible crosslinked polymers, and methods for their preparation and use, are disclosed in which the biocompatible crosslinked polymers are formed from water soluble precursors having electrophilic and nucleophilic groups capable of reacting and crosslinking in situ. Methods for making the resulting biocompatible crosslinked polymers biodegradable or not are provided, as are methods for controlling the rate of degradation. The crosslinking reactions may be carried out in situ on organs or tissues or outside the body. Applications for such biocompatible crosslinked polymers and their precursors include controlled delivery of drugs, prevention of post-operative adhesions, coating of medical devices such as vascular grafts, wound dressings and surgical sealants.

  • Patent number: 6517849
    Abstract: This application relates to antiviral tissue paper comprising pyrrolidone carboxylic acid as an antiviral agent. When added to tissue paper pyrrolidone carboxylic acid has the ability to kill certain strains of viruses which come into contact with the tissue. In addition to its antiviral efficacy, pyrrolidone carboxylic acid tends to be mild to the skin thus mitigating the potential for skin irritation. Furthermore, upon transfer to the skin, pyrrolidone carboxylic acid assists in retention of the natural moisture of the skin while continuing to kill deleterious viruses.
