ABSTRACT:
A vascular access that can be used for hemodialysis and other conditions where a vascular access may be needed. A soft main tube made of PTFE is used with two extension tubes. The ends of the main tube are anastomosed to an artery and a vein. The extension tubes connected to the main tube at one end are connected to the dialysis machine at an opposite end. The entire graft (main tube) is placed in the subcutaneous or deep tissues except for the two exposed ends of the extension tubes which remain in the external position allowing an easy, non-traumatic access to the blood flow.
