System for photovoltaic remote supply by means of optical fibre for implantable medical devices

摘要

Energy supply system for implantable devices. The energy supply is produced by means of the electricity generated by a photovoltaic converter which converts the light arriving via the optical fibre from areas outside the subject. This allows continuous operation of the implanted devices and makes it possible to develop future high-consumption devices as it eliminates the energy limitations which characterize current batteries. The system consists of a light source 1 outside the patient's body, an optical fibre 3 which extends from a surface point on the patient to the implantable device 4 and a photovoltaic converter 5 located inside the device to which the optical fibre reaches. Finally, a conditioning stage 6 is responsible for adjusting the electrical power generated by the photovoltaic converter to the requirements of the remaining components 7 of the implantable device.
