Leviticus Cardio, a company based in Petach Tikva, Israel, has been developing a wireless power transfer technology that they call “Coplanar Energy Transfer” (CET). The system supports high-efficiency (up to 75%) power transfer levels of up to 30 Watts, making it suitable for powering ventricular-assist devices.
Like other transcutaneous energy transfer systems, Leviticus is used on inductive power transfer between an external primary coil and an implanted secondary coil. However, instead of the traditional pancake coil subcutaneous implant, the CET coil is placed around the lung. The unique engineering of the coplanar energy transfer system is characterized by two large rings utilizing a coil-within-the-coil topology, ensuring robust resonance energy transfer Continue reading
