  • Patent number: 7081133
    Abstract: Pannus-resisting implantable medical devices comprise one or more antimicrobial reservoirs, each such reservoir incorporating antimicrobial substances in predetermined distributions for timed release in vivo. Predetermined distributions of antimicrobial substances incorporated in antimicrobial reservoirs are achieved through use of fluid solvent carriers, which may comprise supercritical fluid solvents. Precipitation of antimicrobial substances from such solvent carriers in predetermined distributions is accomplished through evaporation and/or application of heating, cooling or decreased ambient pressure to the solvent carriers.

  • Patent number: 6528107
    Abstract: A method is provided for producing antimicrobial, antithrombogenic medical devices. The method employs an antimicrobial treatment process wherein an antimicrobial agent is dissolved in an appropriate solvent and the resulting solution is contacted with a portion of a medical device of interest. The antimicrobial treatment process is advantageously performed without the need for additional compounds to facilitate antimicrobial agent uptake into the device. The method further comprises an antithrombogenic treatment process wherein antithrombogenic agents or materials are applied or otherwise associated with at least some portion of the medical device.

  • Patent number: 6416549
    Abstract: This invention provides an antithrombogenic annuloplasty rings, and methods for making the same, wherein the annuloplasty rings have a desired degree of initial rigidity to facilitate ease of handling during implantation but which becomes flexible some time after implantation. The annuloplasty ring contains a relatively rigid insert enclosed by a fabric sheath, the insert being at least partly comprised of a biodegradable material. Following surgical implantation of the annuloplasty ring, the rigid insert component of the ring, upon exposure to blood and/or other physiological fluids, undergoes a controlled biodegradation which decreases its rigidity, thereby increasing the flexibility of the implanted annuloplasty ring. Furthermore, at least some portion of the annuloplasty ring has incorporated into or onto its structure one or more antithrombogenic agents or materials in a manner which reduces the likelihood of thrombosis following implantation.
