Abstract

The percutaneous driveline used in contemporary LVADs presents a continuous risk of infection for the duration of support. Minimizing infection in durable mechanical circulatory support systems requires total implantation of all components and energy transfer by means other than percutaneous drivelines. A novel coplanar energy transfer (CET) system, similar to the original transcutaneous energy transfer (TET) design, is unique by incorporating two large rings with coil-within-the-coil topology to ensure strong resonance power. The CET system consists of an internal integrated controller, a battery coupled with an internal thoracic coil ring, and the LVAD pump. External equipment includes a power transmission belt with an external controller, a battery, and wristwatch monitor. The CET system is adaptable to multiple LVAD designs, though the Jarvik 2000 (Jarvik Heart, Inc., New York, NY) with postauricular power cable was used in the initial clinical cases. Two male patients, ages 51 years and 24 years, underwent implantation of the CET/Jarvik 2000 system for the bridge to transplant indication. One patient experienced a stroke and device thrombosis which led to termination of LVAD support while the patient waited for transplantation. The second patient underwent successful transplant after two months of support. The CET functioned as intended in both patients. Larger, multicenter, controlled clinical trials are necessary to determine the long-term safety and efficacy of the CET technology.
