    Abstract: A Kelvin connection scheme, apparatus and method for effectuating residual voltage measurements with respect to one or more electrodes of a lead system associated with an implantable medical device (IMD). In one example implementation, terminals of at least one DC blocking stimulation capacitor or at least one AC-coupling sense capacitor associated with at least one inactive electrode of the lead system are used as one Kelvin connection terminal of a measurement circuit path whereas a counter Kelvin connection terminal with respect to a selection of at least one active electrode is effectuated across the electrode/tissue interface using either at least one DC blocking stimulation capacitor or at least one AC-coupling sense capacitor provided therewith.

    Abstract: An apparatus and method for providing split stimulation currents in a pulse generator. In one embodiment, a current regulator of the pulse generator includes a digitally-programmable analog voltage generator coupled to a first input of an error amplifier that receives a second input controlled by a programmable resistor network configured to control a programmable total stimulation current output. A plurality of current splitting switches are operative to split the programmable total stimulation current output into a corresponding plurality of split current segments, which may be individually mapped to a selected set of lead electrodes across one or more implantable leads associated with the pulse generator.

    Abstract: A neurostimulation (NS) system and method are provided. The NS system includes an array of electrodes positioned within a patient. The array of electrodes includes an active electrode. The active electrode is configured to be a cathode electrode located proximate to neural tissue of interest that is associated with a target region. The NS system includes an anode electrode and an electromagnetic interference (EMI) antenna. A control circuit is configured to control delivery of a NS therapy during a therapy delivery interval. The NS therapy is to be delivered between the anode electrode and the active electrode. The NS system develops a residual voltage between the anode electrode and the active electrode over the therapy delivery interval. A current regulator (CR) circuit is connected to the cathode electrode. The CR circuit is configured to control current flow through the cathode electrodes. During a discharge operation, the control circuit is configured to manage the CR circuit to control a discharge current flow over the discharge operation to discharge the residual voltage after therapy delivery in a manner that follows an actively emulated passive discharge (AEPD) profile. During the discharge operation, the CR circuit is connected to the inactive electrode. The CR circuit receives, as a first input, an EMI feedback signal from the EMI antenna. The CR circuit is configured to regulate the discharge current flow through the active electrode based on the EMI feedback signal, to maintain the AEPD profile over the discharge operation while in a presence of an EMI event.

    Abstract: System and methods for providing a pulsed therapy comprises an implantable pulse generator (IPG) having circuitry configured to control generation and delivery of electrical pulses using at least one electrode of a stimulation lead. The IPG further comprises memory configured to store program instructions and one or more processors configured to execute the program instructions. The one or more processors are configured to deliver the pulses, having a corresponding pulse duration and an amplitude, to the at least one electrode. The amplitude can vary over the pulse duration of at least one of the pulses. The processor(s), monitor a signal indicative of a present level of the amplitude of the at least one pulse, and based on the signal, declare a pulse valid based on the present level satisfying an initial criteria for at a sub-duration of the pulse duration that is less than an entire pulse duration.

    Abstract: Provided is an implantable pulse generator (IPG) for providing electrical pulses to a patient during neurostimulation therapy. The IPG includes a controller for controlling operations of the IPG, a battery for powering the IPG, a therapeutic stimulation circuitry for generating electrical pulses to stimulate neural tissue of the patient, and internal diagnostic circuitry for digitizing device signals to control operations of the IPG. The internal diagnostic circuitry includes a multi-stage comparator including a pre-amplifier configured to receive an analog input signal and convert the analog input signal into a first analog output signal and second analog output signal. The multi-stage comparator also including a first latch circuit with a first receiving device that receives the first analog output signal, a second receiving device that receives the second analog output signal, and configured to convert the first analog output signal and second analog output signal into a digital output signal.

    Abstract: An implantable medical device (IMD) configured to provide stimulation therapy using an instruction set architecture (ISA) includes a main processor operating at a first frequency and a secondary processor operating at a second frequency lower than the first frequency. Example ISA may comprise assembly-language-like instructions that may be executed by the secondary processor for configuring one or more stimulation engines (SEs) to cause stimulation of select electrode sets of a lead system based on one or more pulse definitions and one or more timing definitions corresponding to a therapy program selection effectuated by a user at an external device.
