Abstract
A mobile wireless power system capable of transmitting power through the skin to energize an implanted medical device without percutaneous wires and without precise positioning includes an external mobile wireless power source and an implantable receiving assembly. The mobile wireless power source is wearable by the patient and includes an excitation coil and transmitting resonant coil which are inductively coupled to each other and are housed in a durable housing. The implantable receiving assembly includes a receiving resonant coil and a power pick-up coil which are also inductively coupled to each other. The transmitting and receiving resonant coils are constructed as to have closely matched or identical resonant frequencies so that the magnetic field produced by the transmitting resonant coil is able to cause the receiving resonant coil to resonate strongly.
