Abstract
This study focuses on the development of a new power supply architecture for an implanted cardiac defibrillator (ICD) and a left ventricular assist device (LVAD). In the proposed solution a transcutaneous wireless power transfer technology (WPT) based on magnetic resonance coupling is adopted assuming an on-body transmitting coil and a subcutaneous receiving coil. With this solution, the percutaneous driveline of the LVAD is eliminated, reducing the risk of infection. The WPT receiver is integrated with the ICD. The proposed power supply using a rechargeable ICD battery allows the LVAD to be continuously powered and the ICD battery to be recharged periodically.
