    Abstract: A method of operation of a wireless charger device includes transmitting a wireless charging signal to a receiver device. The method further includes receiving a clamping pulse from the receiver device based on the wireless charging signal. The clamping pulse indicates a first value associated with a falling edge of the clamping pulse and further indicates a second value associated with a rising edge of the clamping pulse. The clamping pulse is detected based on a comparison of a first threshold with the first value and further based on a comparison of a second threshold with the second value, and the second threshold is different than the first threshold. The method further includes determining a charging state of the receiver device based on the clamping pulse.

    Abstract: Systems and methods which provide for and enable sensing responsive signals with respect to the application of paresthesia-free stimulation are described. Sensing signal initiators may be utilized comprising one or more non-therapeutic and/or non-tonic pulses in the form of pinging-pulses configured for invoking responsive signals suitable for measurement and/or analysis in association with the application of neural stimuli. A sensing signal initiator technique may provide an interleaved implementation to introduce one or more pinging-pulses between burst groups of a burst stimulation regimen. Additionally or alternatively, a sensing signal initiator technique may provide a postfixed implementation to introduce one or more pinging-pulses by modifying a therapeutic stimulation burst so that the last phase of the passive discharge is replaced with pinging-pulse providing an active discharge.

    Abstract: The present disclosure provides systems and methods for circuitry for an implantable pulse generator (IPG) of a neurostimulation system. The circuitry includes at least one anode node, at least one cathode node, a plurality of switching circuits, each switching circuit coupled to the at least one anode node and the at least one cathode node, and a plurality of output channels, each output channel coupled between an associated switching circuit and at least one electrode. The circuitry further includes a first DC blocking capacitor coupled between the at least one anode node and the plurality of switching circuits, a second DC blocking capacitor coupled between the at least one cathode node and the plurality of switching circuits. The circuitry further includes mitigation circuitry operable to limit DC leakage from the plurality of switching circuits through the plurality of output channels.

    Abstract: A trajectory guiding apparatus and one or more methods associated therewith for facilitating precision-guided alignment and implantation of a DBS therapy device in a patient. A base plate and base frame combination provides a platform for a dual-stage slider (DSS) assembly comprising a bottom stage slider (BSS) table and a top stage slider (TSS) table that each have suitably sized apertures or orifices therethrough for allowing the passage of and securely holding an instrumentation column (IC) assembly whose translational movement (i.e., sideways or forward and/or backward directions along a translational plane) and pivotal/rotational movement (i.e., around a perpendicular axis orthogonal to the translational plane and extending through a pivot or fulcrum) are independently controlled by respective slide actuators in order to properly align the IC assembly to a desired trajectory.

    Abstract: Stimulation lead includes an elongated lead body having distal and proximal ends and wire conductors extending therebetween. The stimulation lead also includes a lead paddle having a multi-dimensional array of electrodes positioned along a contact side of the lead paddle. The electrodes are electrically coupled to the wire conductors. The lead paddle includes a paddle body and a conductor organizer disposed within the paddle body. The conductor organizer has multiple channels extending along the lead paddle. The channels receive the wire conductors and retain the wire conductors in a designated arrangement with respect to the lead paddle. The conductor organizer has openings to the channels. The wire conductors extend through the openings and are terminated to the respective electrodes.

    Abstract: The present disclosure provides systems and methods for wirelessly charging an implantable medical device. An external charging device includes a coil, signal generating circuitry to drive current through the coil at a charging frequency to induce current in a second coil in the implantable medical device, monitoring circuitry to generate an output signal to monitor charging operations, and a comb filter. The comb filter is configured to apply filtering to the output signal to remove noise from the output signal, wherein the filtering is applied based on the charging frequency. The external charging device is configured to process the filtered output signal to detect a circuit state of charging circuitry of the implantable medical device during charging operations, and the external charging device is configured to vary the charging frequency based, in part, on detection of the circuit state of the charging circuitry of the implantable medical device.
