Abstract
A transponder includes a stimulus driver configured to discharge an electrical stimulus when a trigger signal is received. A first conducting electrode is coupled to the stimulus driver and conducts the electrical stimulus discharged by the stimulus driver. A second conducting electrode is coupled to the stimulus driver and conducts the electrical stimulus conducted by the first conducting electrode. A depolarization resistance connects the first conducting electrode to the second conducting electrode in response to the trigger signal.
Claims20
A method of providing stimulation pulses to tissue, comprising the steps of:
- providing stimulation pulses to said tissue:
- and
- reducing polarization in said tissue.
A wireless stimulation method comprising:
- wirelessly powering an implanted electronic unit;
- using said implanted unit to provide stimulation pulses to surrounding tissue, over a voltage range in which said tissue has nonlinear impedance;
- and
- reducing polarization of said tissue by dampening said pulses with a resistive path, in the implanted electronic unit, which has a real resistance component which is larger than the magnitude of differential impedance of the tissue at the full amplitude of said pulses, and smaller than the magnitude of differential impedance of the tissue when the amplitude of said pulses is at 10% of its maximum.
(canceled)
A stimulation driver to provide discontinuous stimulation pulses to cellular matter comprising:
- biocompatible electrodes receiving discontinuous stimulation pulses;
- a resistive connection between said biocompatible electrodes and having a time constant such that polarization of the cellular matter is reduced between said discontinuous stimulation pulses.
