CorWave utilizes a completely novel approach to pumping blood. The undulating polymer membrane gently pushes the blood on both sides of a membrane, from the outer edge to the inner orifice, where it exits the pump. A magnetic actuator drives the membrane oscillation at a rate of 120 cycles per second, allowing precise adjustment to the flow profile during a typical cardiac cycle.
The same fundamental technology can be applied to a flat membrane. In this version, flow is created in an axial orientation as the wave is generated along the length of the membrane. This version of the pump may be configured for partial support and endovascular applications.
