  • Title: Toward total implantability using free-range resonant electrical energy delivery system: achieving untethered ventricular assist device operation over large distances.
    Author: Waters B, Sample A, Smith J, Bonde P.
    Journal: Cardiol Clin; 2011 Nov; 29(4):609-25. PubMed ID: 22062212.
    Abstract:
    Heart failure is a terminal disease with a very poor prognosis. Although the gold standard of treatment remains heart transplant, only a minority of patients can benefit from transplants. Another promising alternative is mechanical circulatory assistance using ventricular assist devices. The authors envision a completely implantable cardiac assist system affording tether-free mobility in an unrestricted space powered wirelessly by the innovative Free-Range Resonant Electrical Energy Device (FREE-D) system. Patients will have no power drivelines traversing the skin, and this system will allow power to be delivered over room distances and will eliminate trouble-prone wirings, bulky consoles, and replaceable batteries.
