摘要： A body lumen access system comprises a distal access cannula and a proximal access cannula. The distal access cannula is attached to or within the body lumen and the proximal access cannula is attached to an implantable port or is transcutaneously positioned and attached to a luer or other external connector. The distal and proximal access cannulas are usually implanted separately, cut to length, and attached at a subcutaneous junction location. Preferably, the proximal access cannula has a larger lumen diameter than that of the distal access cannula in order to reduce flow resistance within the cannula system. In some cases the distal and proximal access cannulas may be formed integrally.

摘要： Implantable ports and other devices are disinfected by the injection of an anti-microbial agent into a tissue pocket surrounding the device. In a first embodiment, the anti-microbial agent is injected through an aperture in the device to flush internal regions of the device before infusing the tissue pocket. In other embodiments, the anti-microbial agent is injected directly to a target site on the exterior of the device. Implantable devices may include special, usually hardened, target regions for receiving the sharpened end of a needle used to inject the anti-microbial agent.

摘要： Implantable ports and other devices are cleansed by the injection of a washing solution into a region in the device or in a tissue pocket surrounding the device. In a first embodiment, the washing solution is injected through an aperture in the device to flush internal regions of the device before infusing the tissue pocket and flushing outwardly through a tissue tract leading to the device. In other embodiments, the washing solution is injected directly to a target site on the exterior of the device. Implantable devices may include special, usually hardened, target regions for receiving the sharpened end of a needle used to inject the washing solution. Kits will include devices, syringes, access devices, and instructions for cleansing according to the methods of the present invention.

摘要： Systems and methods balance fluid in a fluid processing procedure during which an outgoing fluid is removed from an individual and an ingoing fluid is supplied to the individual. The systems and methods supply a volume of the outgoing fluid and a volume of the ingoing fluid into a volumetric chamber. The systems and methods discharge a volume of the outgoing fluid and a volume of the ingoing fluid from the volumetric chamber. The systems and methods synchronizes the supply and discharge of fluid to affect a concurrent discharge of the outgoing fluid and ingoing fluid from the volumetric chamber in volumetric balance with a concurrent supply of outgoing fluid and ingoing fluid into the volumetric chamber. The volumetric chamber can include at least one chamber including an interior wall dividing the chamber into a first compartment and a second compartment. The first compartment retains a volume of outgoing fluid. The second compartment retains a volume of ingoing fluid. The interior wall responds to differential fluid pressure to discharge the ingoing fluid from the second compartment as the outgoing fluid is conveyed into the first compartment, and vice versa.

摘要： 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.

摘要： 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.

摘要： Implanted catheters are locked with a solution comprising a lower alcohol, typically ethanol, propanol, or butanol, most preferably isopropanol. The use of an alcohol can both reduce fouling of the catheter, particularly clotting and thrombus in intravascular catheters, as well as reducing the risk of infection. The risk of infection can be further reduced by employing a catheter body which is sufficiently porous to permit the lower alcohol or other anti-microbial solution to penetrate into the catheter body and preferably through the catheter into tissue surrounding the implanted catheter.
