Devices and methods for connecting implantable devices to wireless energy

A system for modulating excitable tissue in a body of a patient comprising:

• a connector receiver device for connecting to an implantable lead in the patient's body, the entire connector receiver device being implantable inside the patient's body and comprising;
• one or more non-loop antennas;
• one or more connection pads;
• and
• an electronic circuit coupled to the non-inductive antennas and the connection pads;
• a control device having a transmitter located outside of the patient's body and configured to transmit an input signal containing electrical energy and waveform parameters to the non-loop antennas through non-inductive coupling;
• and
• wherein the input signal is transmitted through a carrier signal having a frequency higher than 50 MHz;
• wherein the electronic circuit is configured to convert the waveform parameters into one or more electrical impulses sufficient to modulate excitable tissue;
• wherein the connection pads are longitudinally along an inner surface of a void that is substantially central and enclosed within the connector receiver device, the connection pads configured to couple with one or more electrodes in the implantable lead and form an electric connection over which the connection pads provide the one or more pulses from the electronic circuit to the electrodes in the implantable lead, the implantable lead being separate from the connector receiver device, and the one or more non-loop antennas, the electronic circuitry, and the one or more connection pads are integrally enclosed in a tubular structure, and
• wherein the connector receiver device is free from an on-board energy storage component.
