| 20080269828 | Non-Invasive Battery Recharger for Electronic Cardiac Implants - The present invention refers to a device used to recharge the battery of electronic cardiac implants, like implanted pacemakers and defibrillators. It can be used to recharge the battery after an emergency requirement, such as: defibrillation or in diagnosis and or reprogramming of implants, during which no energy is demanded from the internal battery, seeing that the energy feed becomes guaranteed (accepted) by the proposed device. The invention is composed by three essential components: a generator (A), a transmitter unit (B) and a receptor coil (C). The generator is destined to produce an energy signal with determined amplitude and frequency and that is carried across through a coaxial cable to the transmitter unit (B). The emitted magnetic field is captured by the receptor coil (C) that is implanted inside the human body, generating a voltage with the absence of the Gibbs phenomenon. Furthermore, the battery recharging device guarantees the energetic supply of a communication channel between the exterior for diagnosis and/or implant reprogramming. In this case, there will be no demand of energy from the internal battery. | 10-30-2008 |
