Devices and methods for connecting implantable devices to wireless energy
First Claim
1. A device for providing an implantable lead with wireless energy, the device comprising:
- a housing configured to package the device suitable for implantation in a patient'"'"'s body;
one or more non-loop antennas substantially enclosed within the housing and configured to non-inductively receive electromagnetic energy radiated from a source located outside of the patient'"'"'s body and through a carrier signal having a frequency higher than 50 MHz;
electronic circuitry coupled to each of the one or more non-loop antennas and configured to extract electric power and excitation waveforms from the radiated electromagnetic energy as non-inductively received by the one or more non-loop antennas; and
one or more connection pads spaced longitudinally along an inner surface of a void that is substantially central and enclosed within the housing for implanting the device inside the patient'"'"'s body,wherein the housing is integrally shaped to enclose the one or more non-loop antennas, the electronic circuitry, and the one or more connection pads with a form factor of a tubular structure,wherein the connection pads are configured to couple with one or more electrodes in the implantable lead and form an electric connection over which the connection pads provide the extracted excitation waveforms from the electronic circuit to the electrodes in the implantable lead, the implantable lead being separate from the device, andwherein the device is free from an on-board energy storage component.
