Abstract: Embodiments are directed to an implantable medical device comprising stimulation circuitry for controlling delivery of a medical therapy to a patient, a processor for controlling the IMD according to executable code, and a power source. The implantable medical device may further include current regulator circuitry comprising electrode selection circuitry that is configured to select electrodes for use during a discharge mode, and a programmable current regulator configured to provide an exponentially decreasing discharge current to the selected electrodes from the power source. A current output of a programmable current regulator may be decreased in precalculated steps to create the exponentially decreasing discharge current applied to the selected electrodes.

Abstract: An implantable medical device (IMD) includes multiple stimulation engines for independently stimulating respective electrode sets of a lead system while avoiding collisions and/or channel contention during stimulation delivery. A first voltage multiplier is configured to generate an adjustable target voltage having sufficient headroom at an output node that is commonly coupled to anodic nodes of respective stimulation engines. Each stimulation engine includes a secondary voltage multiplier to drive the respective anode and a current regulator powered by a floating voltage supply, wherein the current regulator is coupled to a cathodic node and configured to control how much stimulation current is pulled from the patient tissue.

Abstract: A neurostimulation system (NS) includes an array of electrodes positioned within a patient with an active cathode electrode located proximate to target neural tissue. A control circuit is controls delivery of therapy during a therapy delivery interval, with the therapy being delivered between an anode electrode and the active electrode. A current regulator circuit (CRC) is connected to the cathode electrode and controls current flow through the cathode electrodes. The control circuit manages the CRC to control a discharge current flow over the discharge operation to discharge developed residual voltage between the anode electrode and the active electrode in a manner that follows an actively emulated passive discharge (AEPD) profile. During the discharge operation, the CRC is connected to the inactive electrode, and receives, as a first input, an EMI feedback signal. The CRC regulates the discharge current flow through the active electrode based on the EMI feedback signal, to maintain the AEPD profile over the discharge operation during an EMI event.
