ABSTRACT:
The present invention is an implantable vascular device which has the ability to open and close without the formation of thrombi. The device comprises at least one shunt which maintains a valve system. This shunt is surgically grafted to a blood line for enabling fluid flow through the shunt when the valve system is in an opened state. This will provide a device which is well suited for use in hemodialysis because the shunt can be opened for hemodialysis and closed when not in use. The destructive problems associated with the high flow states is limited only to the short time interval of the hemodialysis.
