Methods And Kits For Locking And Disinfecting Implanted Catheters

US Patent:
6685694, Feb 3, 2004
Filed:
May 16, 2001
Appl. No.:
09/859886
Inventors:
Charles D. Finch - Clinton MS
Paul F. Marad - Andover MA
John Wang - Sammamish WA
James M. Brugger - Newburyport MA
Assignee:
Vasca, Inc. - Tewksbury MA
International Classification:
A61M 3100
US Classification:
604508, 604523, 604500, 604256, 604 9301, 604537
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.

Methods And Kits For Locking And Disinfecting Implanted Catheters

US Patent:
6679870, Jan 20, 2004
Filed:
Jul 7, 2000
Appl. No.:
09/611421
Inventors:
Charles D. Finch - Clinton MS
John H. Wang - Sammamish WA
Paul F. Marad - Andover MA
James M. Brugger - Newburyport MA
Assignee:
Vasca, Inc. - Tewksbury MA
International Classification:
A61M 3100
US Classification:
604500, 604 9301, 604523, 5142225
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.
