Transcutaneous energy transfer system with multiple secondary coils
First Claim
Patent Images
1. A transcutaneous energy transfer system, comprising:
- a plurality of secondary coils comprising a first secondary coil and a second secondary coil, said first and second secondary coils adapted for disposition in a patient to receive transcutaneous energy;
first and second primary coils configured to simultaneously transmit transcutaneous energy to one of the first and second secondary coils; and
a controller, also adapted for disposition in the patient, comprising circuitry to isolate the first and second secondary coils from each other while also allowing each of the first and second secondary coils to simultaneously charge a storage device and/or power an implantable medical device when each of the first and second secondary coils is simultaneously coupled to the first and second primary coils, respectively.

Abstract
A transcutaneous energy transfer (TET) system is provided having a plurality of secondary coils adapted for disposition in a patient, at least one primary coil configured to transmit transcutaneous energy, and a controller adapted for disposition in a patient. The controller includes circuitry to isolate the secondary coils from each other and direct electric current from at least one of the secondary coils to a charge storage device and/or implantable medical device.

9. An implantable device, comprising:
-
first and second secondary coils disposable in a patient and adapted to produce an electric current in a presence of a time-varying magnetic field; and a control circuitry to isolate the first and second secondary coils from each other while also directing electric current from both of the secondary coils to an electric storage device and/or an implantable medical device when each of the secondary coils is simultaneously coupled to a first and a second primary coil, respectively. - View Dependent Claims (10, 11, 12, 13, 14, 15)
