An implantable ventricular assist device is described which has only one moving part. This part consists of a conical rotor with vanes which spiral upward from the base in a direction opposite to the direction of rotation. There are no valves within the device itself, but one or two valves are situated in the conduits connected to it. The device is powered by a constant running electric motor which screws into the base of the rotor housing. The motor is connected to a portable external battery by means of subcutaneous electrical leads. |
