An implantable electronic device includes a flexible circuit board, one or more circuit components attached to the flexible circuit board and configured to convert electrical energy into electrical pulses, and one or more electrodes attached to the flexible circuit board without cables connecting the electrodes to each other or to the flexible circuit board, the one or more electrodes configured to apply the electrical pulses to a tissue adjacent the implantable electronic device.

Implantable electronic devices

Implementations provide a method that includes: placing a controller device over a surface region of the patient where the implantable wireless stimulation device has been implanted; configuring the controller device to (i) monitor a return loss representing electrical power reflected from the implantable wireless stimulation device to the controller device; (ii) compute a first path loss metric based on a first monitored return loss when the controller device is place over a first location within the surface region; (iii) compute a second path loss metric based on a second monitored return loss when the controller device is over a second location within the surface region; and (iv) generate a feedback to an operator to indicate whether the second path loss is smaller than the first path loss such that the controller device is placed at a location with more electrical energy non-inductively transferred to the implantable wireless stimulation device.

Systems and methods to locate an implantable stimulator device inside a subject

A method includes: transmitting a first set of radio-frequency (RF) pulses to an implantable wireless stimulator device such that electric currents are created from the first set of RF pulses and flown through a calibrated internal load on the implantable wireless stimulator device; in response to the electric currents flown through a calibrated internal load, recording a first set of RF reflection measurements; transmitting a second set of radio-frequency (RF) pulses to the implantable wireless stimulator device such that stimulation currents are created from the second set of RF pulses and flown through an electrode of the implantable wireless stimulator device to tissue surrounding the electrode; in response to the stimulation currents flown through the electrode to the surrounding tissue, recording a second set of RF reflection measurements; and characterizing an electrode-tissue impedance by comparing the second set of RF reflection measurements with the first set of RF reflections measurements.

Systems and methods to sense stimulation electrode tissue impedance

A system includes a controller module, which includes a storage device, a controller, a modulator, and one or more antennas. The storage device is stored with parameters defining a stimulation waveform. The controller is configured to generate, based on the stored parameters, an output signal that includes the stimulation waveform, wherein the output signal additionally includes polarity assignments for electrodes in an implantable, passive stimulation device. The modulator modulates a stimulus carrier signal with the output signal to generate a transmission signal. The one or more antennas transmit the transmission signal to the implantable, passive stimulation device such that the implantable, passive stimulation device uses energy in the transmission signal for operation, sets the polarities for the electrodes in the implantable, passive stimulation device based on the encoded polarity assignments, generates electrical pulses using the stimulation waveform, and applies the electrical pulses to excitable tissue.

Microwave field stimulator

An implantable wireless lead includes an enclosure, the enclosure housing: one or more electrodes configured to apply one or more electrical pulses to a neural tissue; a first antenna configured to: receive, from a second antenna and through electrical radiative coupling, an input signal containing electrical energy, the second antenna being physically separate from the implantable neural stimulator lead; one or more circuits electrically connected to the first antenna, the circuits configured to: create the one or more electrical pulses suitable for stimulation of the neural tissue using the electrical energy contained in the input signal; and supply the one or more electrical pulses to the one or more electrodes, wherein the enclosure is shaped and arranged for delivery into a subject's body through an introducer or a needle.

Implantable lead

Some implementations provide a method for modulating excitable tissue in a body of a patient, the method including: placing a wireless implantable stimulator device at a target site in the patient's body, the stimulator device including one or more electrodes; reconfiguring the wireless implantable stimulator device to form an enclosure that substantially surrounds the excitable tissue at the target site with the electrodes on the inside of the enclosure and facing the nerve; and causing electrical impulses to be delivered to the electrodes on the wireless implantable stimulator device such that neural modulation is applied to the excitable tissue substantially surrounded by the enclosure.

System and method for stimulation with electrode

An implantable neural stimulator method for modulating excitable tissue in a patient including: implanting a neural stimulator within the body of the patient such that one or more electrodes of the neural stimulator are positioned at a target site adjacent to or near excitable tissue; generating an input signal with a controller module located outside of, and spaced away from, the patient's body; transmitting the input signal to the neural stimulator through electrical radiative coupling; converting the input signal to electrical pulses within the neural stimulator; and applying the electrical pulses to the excitable tissue sufficient to modulate said excitable tissue.

A system, including: an implantable neural stimulator including electrodes, at least one antenna and an electrode interface; a radio-frequency (RF) pulse generator module comprising an antenna module configured to send an input signal to the antenna in the implantable neural stimulator through electrical radiative coupling, the input signal containing electrical energy and polarity assignment information that designates polarity assignments of the electrodes in the implantable neural stimulator; and wherein the implantable neural stimulator is configured to: control the electrode interface such that the electrodes have the polarity assignments designated by the polarity assignment information, create one or more electrical pulses suitable for modulation of neural tissue using the electrical energy contained in the input signal, and supply the electrical pulses to the electrodes through the electrode interface such that the electrodes apply the electrical pulses to the neural tissue with the polarity assignments designated by the polarity assignment information.
