  • Publication number: 20250114509
    Abstract: An arteriovenous graft system including an arteriovenous graft with a valve device. The valve device has an open state in which fluid flow through the graft is possible, and a closed state in which the fluid flow through the arteriovenous graft is blocked. The graft system includes an actuator device to actuate the valve device between the closed state and the open state. A transmission cable connects the actuator device with the valve device. The actuator device includes at least one movable magnet that connects to a rotatable plate which is equipped with a spiralled groove. The spiralled groove receives a pin that is movable in a linear path. The pin is connected to the transmission cable so as to arrange that motion of the magnet translates into a linear displacement of the pin and the transmission cable connected thereto.

  • Patent number: 12059339
    Abstract: A subcutaneous arteriovenous graft system includes an arteriovenous graft having an arterial end, a venous end opposite to the arterial end and an internal volume between the arterial end and the venous end, and a valve device that can be arranged in an open state, in which fluid flow through the graft is possible and a closed state in which the fluid flow through the arteriovenous graft is blocked. The valve device is constructed to decrease, in the closed state of the valve device, the internal volume of the complete graft to substantially zero.

  • Patent number: 10933163
    Abstract: The present disclosure relates to in situ tissue engineering, more specifically in situ vascular tissue engineering with the aim of providing a tissue structure which can be used e.g. as a substitute blood vessel or as a blood vessel functioning as cannulation site in hemodialysis. In particular, the disclosure involves tissue structure formation around a subcutaneously implanted synthetic rod. In addition, the disclosure involves a method for producing said synthetic rod.
