Abstract 19865: Remote Electrical Power Delivery to Run LVAD Across a Meter Distance: Innovation and Validation Using Free-Range Electrical Energy Delivery (FREE-D) System in vivo

Introduction: Models of power delivery within an intact organism have been limited to ionizing radiation, sound u0026 magnetic waves. We present experimental validation of remote electrical power delivery to an intact biological system using magnetic resonant coupling technology, allowing continuous operation of LVAD, without being dependent on implanted batteries alone at an unprecedented distance of one meter. Methods: Four Yorkshire pigs were implanted with HVAD device powered and controlled by a wireless power delivery. The implanted coil was separated from transmitting coil within a 3 dimensional space of one meter diameter. Results: All experiments were successfully concluded without any power drop or interruption. Electrical power was delivered to the implanted coil within a one meter diameter circle. Temperature rose to one degree celsius at the receiving coil. HVAD device could be run either in continuous or pulsed mode. The experiment used an implanted coil (5cm), a coil worn in a vest and a coil pl...
