The TORVAD is a Toroidal Ventricular Assist Device. VADs are fully implantable blood pumps that increases cardiac output for patients with heart failure. The TORVAD produces pulsatile ejections with two independently controlled pistons. One piston acts as a virtual valve while the other rotates around the toroidal pumping chamber and simultaneously aspirates and ejections blood by positive-displacement. The pistons are magnetically coupled to motors that have precise position and motion control. This technology is completely unique, the only two-piston pump of it’s kind, and is protected by six approved patents.
