Abstract:
An arteriovenous shunt for surgical implantation comprising:a main tube having two ends for subcutaneous implantation and respective connection to a side of a peripheral artery and a side of a peripheral vein,two extension tubes, each of said two extension tubes having two ends with one end of said two extension tubes being subcutaneously connected to said main tube and an opposite free end of said two extension tubes terminating in a hemostatic valve for connection to an input and an output, respectively, of a dialysis machine,said two extension tubes extending substantially parallel and adjacent to each other from said free end towards said one end of said two extension tubes over a majority of their respective lengths so as to exit from the skin of a patient through a single outlet port, anda separation distance between said one end of each of said two extension tubes subcutaneously connected to said main tube being sufficient for dialyzed blood to join venous circulation while avoiding recirculation of the dialyzed blood back to the dialysis machine and close enough so that said two extension tubes exit through said single outlet port to reduce exposure of the patient to a risk of infection.
