Abstract
An arterio-venous graft (16) is provided with a constriction device (20) near its arterial end. The constriction device (20) is used to reduce the flow through the AV graft under normal conditions and to relieve the constriction when high flow through the AV graft is required, such as for vascular access for hemodialysis.
