The Heart Failure Society of America (HFSA) published today a new Scientific Statement titled “Update on Device Based Therapies in Heart Failure.”  The statement was published online in the Journal of Cardiac Failure (JCF).

This statement discusses how novel device-based therapies, including CCM, BAT, and remote monitoring may bridge current gaps in HF treatment and outcomes.  The statement also proposes a clinical pathway to implement FDA approved device-based therapies that align with current HF management workflow.

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→
