  • Patent number: 6685694
    Abstract: Implanted catheters are locked with a solution comprising a lower alcohol, typically ethanol, propanol, or butanol, in a range from 1% to 99% by volume, and an additive in a range from 1% to 99% by volume, the additive comprising an anti-microbial, typically taurolidine or triclosan, or an anti-coagulant, typically riboflavin, sodium citrate, ethylene diamine tetraacetic acid, or citric acid. The use of an alcohol and additive solution can effectively reduce fouling of the catheter, particularly clotting and thrombus in intravascular catheters, as well as eradicate existing infections and/or reduce the risk of potential infections. Existing infections and/or potential infections can be further reduced by employing a catheter body which permits an anti-microbial solution to penetrate into the catheter body and preferably through the catheter into tissue surrounding the implanted catheter.
    Type: Grant
    Filed: May 16, 2001
    Date of Patent: February 3, 2004
    Assignee: Vasca, Inc.
    Inventors: Charles D. Finch, Paul F. Marad, John Wang, James M. Brugger
  • Patent number: 6679870
    Abstract: Implanted catheters are locked with a solution comprising a lower alcohol, typically ethanol, propanol, or butanol, most preferably isopropanol, and an additive, the additive comprising an anti-microbial, typically taurolidine or triclosan, or an anti-coagulant, typically riboflavin, sodium citrate, ethylene diamine tetraacetic acid, or citric acid. The use of an alcohol and additive solution can effectively reduce fouling of the catheter, particularly clotting and thrombus in intravascular catheters, as well as reduce the risk of infection. The risk of infection can be further reduced by employing a catheter body which is sufficiently porous to permit the anti-microbial solution of a lower alcohol and another anti-microbial or anti-coagulant compound to penetrate into the catheter body and preferably through the catheter into tissue surrounding the implanted catheter.
