Vascular access implant and access implant system

A vascular access implant for connecting an intracorporeal blood circulation to an extracorporeal blood circulation, the vascular access implant comprising:

• an arterial fluid line adapted to be permanently connected to an artery of a patient;
• a venous fluid line adapted to be permanently connected to a vein of the patient;
• a controllable artery-vein-connection between the arterial fluid line and the venous fluid line that controls a fluid flow between the arterial fluid line and the venous fluid line;
• an arterial port which is in fixed fluid connection with the arterial fluid line and is adapted, as an arterial access, for coupling to and decoupling from a first hose of the extracorporeal blood circulation;
• and
• a venous port which is in fixed fluid connection with the venous fluid line and is adapted, as a venous access, for coupling to and decoupling from a second hose of the extracorporeal blood circulation.
