    摘要： Architectures for an implantable neurostimulator system having a plurality of electrode-driver integrated circuits (ICs) in provided. Electrodes from either or both ICs can be chosen to provide stimulation, and one of the IC acts as the master while the other acts as the slave. A parallel bus operating in accordance with a communication protocol couples the ICs, and certain functional blocks not needed in the slave are disabled. Stimulation parameters are loaded via the bus into each IC, and a stimulation enable command is issued on the bus to ensure simultaneous stimulation from the electrodes on both ICs. Clocking strategies are also disclosed to allow clocking of the master and slave ICs to be independently controlled, and to ensure that relevant internal and bus clocks used in the system are synchronized.

    摘要： Electrode voltage monitoring circuitry for an implantable neurostimulator system having a plurality of electrode-driver integrated circuits (ICs) in provided. Electrodes from either or both ICs can be chosen to provide stimulation, and one of the IC acts as the master while the other acts as the slave. Electrodes voltages on the slave IC are routed to the master IC, and thus the master IC can monitor both electrode voltages on the slave as well as electrode voltages on the master. Such voltages can be monitored for a variety of purposes, and in particular use of such voltage is disclosed for determining the resistance between electrodes and to set a compliance voltage for stimulation.

    摘要： An improved arbitration scheme for allowing concurrent stimulation and telemetry listening in a microstimulator is disclosed. A listening window for telemetry is permitted to proceed, and access to the microstimulator's coil granted, during at least a portion of the inter-pulse period that follows the issuance of a stimulation pulse. This is permissible because access to the coil is not needed during the entirety of the inter-pulse period. For example, the listening window can issue during that portion of the inter-pulse period when the decoupling capacitor is discharged, but cannot issue during that portion of the inter-pulse period when the compliance voltage is being generated for the next stimulation pulse. However, because compliance voltage generation occupies only a small portion of the inter-pulse period, the technique is not substantially limited. By allowing the listening window to issue during the majority of the inter-pulse period, the listening window produces smaller gaps between the pulses, and stimulation therapy is thus brought closer to its ideal.

    摘要： An improved architecture for an implantable medical device such as an implantable pulse generator (IPG) is disclosed. In one embodiment, the various functional blocks for the IPG are incorporated into a signal integrated circuit (IC). Each of the functional blocks communicate with each other, and with other off-chip devices if necessary, via a centralized bus governed by a communication protocol. To communicate with the bus and to adhere to the protocol, each circuit block includes bus interface circuitry adherent with that protocol. Because each block complies with the protocol, any given block can easily be modified or upgraded without affecting the design of the other blocks, facilitating debugging and upgrading of the IPG circuitry. Moreover, because the centralized bus can be taken off the integrated circuit, extra circuitry can easily be added off chip to modify or add functionality to the IPG without the need for a major redesign of the main IPG IC.

    摘要： Disclosed herein are methods and circuitry for monitoring and adjusting a compliance voltage in an implantable stimulator devices to an optimal value that is sufficiently high to allow for proper circuit performance (i.e., sufficient current output), but low enough that power is not needlessly wasted via excessive voltage drops across the current output circuitry. The algorithm measures output voltages across the current source and sink circuitry during at least periods of actual stimulation when both the current sources and sinks are operable, and adjusts the compliance voltage so as to reduce these output voltages to within guard band values preferably indicative for operation in transistor saturation. The output voltages can additionally be monitored during periods between stimulation pulses to improve the accuracy of the measurement, and is further beneficial in that such additional measurements are not perceptible to the patient.

    摘要： Sample and hold circuitry for monitoring electrodes and other voltages in an implantable neurostimulator is disclosed. The sample and hold circuitry in one embodiment contains multiplexers to selected appropriate voltages and to pass them to two storage capacitors during two different measurement phases. The capacitors are in a later stage serially connected to add the two voltages stored on the capacitors, and voltages present at the top and bottom of the serial connection are then input to a differential amplifier to compute their difference. The sample and hold circuitry is particularly useful in calculating the resistance between two electrodes, and is further particularly useful when resistance is measured using a biphasic pulse. The sample and hold circuitry is flexible, and can be used to measure other voltages of interest during biphasic or monophasic pulsing.
