Rechargeable battery system for implantable medical device

Abstract

With increasing cardiovascular diseases and heart failures, heart transplantation has become a demanding health problem. In addition to the problem, there is a serious shortage of donor hearts. Under this situation, the need for artificial heart replacement has grown tremendously. One such replaceable Total Artificial Heart (TAH) is the Abiocor system. A significant development of recent TAH is its design and implanted devices that allow the patient to be free without many restrictions; mainly the patient is allowed to be mobile and can return to many of the activities performed before heart failure. The TAH consists of a set of internal and external components. The internal components are those located inside the patient's body; they are the artificial heart, the internal Transcutaneous Energy Transmission (TET), the implanted controller and battery components.
