“…The unit is powered and monitored/controlled via the energy and information transfer coils, which allow transcutaneous transfer of energy and information through intact skin and tissue, thus eliminating the need for percutaneous connections (17)(18)(19)(20)(21). The energy transfer system provides power to operate the VAD unit from a wearable external battery or other power source (automobile cigarette lighter, Household AC outlet, etc.).…”

Currently, the most widely utilized ventricular assist devices (VADs) require percutaneous connections and are located either externally (e.g., Thoratec, Abiomed) or intra-abdominally (e.g., Novacor, TCI). These attributes have been implicated in a variety of complications (infection, thromboembolic, gastrointestinal, etc.). To address these concerns, a totally implantable VAD that requires no percutaneous connections and can be implanted in the left hemi-thorax has been developed. The developed device has undergone in vivo evaluation as part of the design and development process. A total of 43 implants in the bovine model, with 5 device versions, have been conducted between July 1992 and February 2000. These studies successfully have demonstrated several important aspects of the developed device, including 1) feasibility of a totally implantable system; 2) capability of the device to support a dysfunctional heart; and 3) ability of the device to provide flows up to 10 L/min in a physiological setting. The studies to date have played a vital role in the design and development process as well as demonstrating the feasibility of a totally implantable intrathoracic VAD. Based on these studies, design optimization was conducted, resulting in the development of the pre-clinical version of the device in preparation for clinical trials.

“…Although the early efforts to design a transcutaneous energy transfer system is referenced back to 1960 [6], the main contributions to this technology, as the pa per review suggests, have been made after 1980 [l]- [7]. Among the contributions made to enhance the design of a transcutaneous transformer, Soma [8] introduced an algorithmic analytical method for designing a transcutaneous transformer.…”
