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： 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： Battery management circuitry for an implantable medical device such as an implantable neurostimulator is described. The circuitry has a T-shape with respect to the battery terminal, with charging circuitry coupled between rectifier circuitry and the battery terminal on one side of the T, and load isolation circuitry coupled between the load and the battery terminal on the other side. The load isolation circuitry can comprise two switches wired in parallel. An undervoltage fault condition opens both switches to isolate the battery terminal from the load to prevent further dissipation of the battery. Other fault conditions will open only one the switches leaving the other closed to allow for reduced power to the load to continue implant operations albeit at safer low-power levels. The battery management circuitry can be fixed in a particular location on an integrated circuit which also includes for example the stimulation circuitry for the electrodes.

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.

摘要： An improved implantable pulse generator (IPG) containing improved telemetry circuitry is disclosed. The IPG includes charging and telemetry coils within the IPG case, which increases their mutual inductance and potential to interfere with each other; particularly problematic is interference to the telemetry coil caused by the charging coil. To combat this, improved telemetry circuitry includes decoupling circuitry for decoupling the charging coil during periods of telemetry between the IPG and an external controller. Such decoupling circuitry can comprise use of pre-existing LSK circuitry during telemetry, or new discrete circuitry dedicated to decoupling. The decoupling circuitry is designed to prevent or at least reduce induced current flowing through the charging coil during data telemetry. The decoupling circuitry can be controlled by the microcontroller in the IPG, or can automatically decouple the charging coil at appropriate times to mitigate an induced current without instruction from the microcontroller.

摘要： Disclosed are methods for synchronizing the time basis of logged data between an implantable medical device such as an IPG and an external device. The IPG logs various operational parameters as data and associates the same with a possibly- inaccurate IPG time stamp and a sequence number. Periodically, the external device sends accurate true time data to the IPG, which, like the operational parameter data, is logged with an IPG time stamp and a next sequence number. The IPG then orders the data sequences and timing sequences by time stamp in a combined data log, and divides that data log into regions in accordance with reset conditions apparent in the time stamp data. Slopes indicative of the relation between true time and time stamps are calculated for various regions on an intra- region or inter-region basis, which then allows for true time estimates to be calculated for the data sequences, thus providing an accurate time basis for the logged data. The true time estimates for the data sequences may then be transmitted from the IPG to an external device for interpretation.

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.
摘要翻译：公开了一种用于允许微型激励器中的并发刺激和遥测监听的改进的仲裁方案。允许进行遥测的监听窗口，并且在发出刺激脉冲之后的脉冲间期间的至少一部分期间允许访问微型激励器的线圈。这是允许的，因为在整个脉冲间期间不需要对线圈的访问。例如，当解耦电容器放电时，在脉冲周期的该部分期间可以发出监听窗口，但是当为下一个刺激脉冲产生顺从性电压时，不能在脉冲间期间的那部分期间发出监听窗口。然而，由于顺应性电压产生仅占脉冲周期的一小部分，所以该技术基本上不受限制。通过允许在大多数脉冲间期间发出听音窗口，收听窗口在脉冲之间产生较小的间隙，因此刺激疗法更接近其理想。

摘要： Improved compliance voltage generation circuitry for a medical device is disclosed. The improved circuitry in one embodiment comprises a boost converter and a charge pump, either of which is capable of generating an appropriate compliance voltage from the voltage of the battery in the device. A telemetry enable signal indicating whether the implant's transmitter, receiver, or both, have been enabled is received. A "boost" signal from compliance voltage monitor-and-adjust logic circuitry is processed with the telemetry enable signal and its inverse to selectively enable either the charge pump or the boost converter: if the telemetry enable signal is not active, the boost converter is used to generate the compliance voltage; if the telemetry enable signal is active, the charge pump is used. Because the charge pump circuitry does not produce a magnetic field, the charge pump will not interfere with magnetically-coupled telemetry between the implant and an external controller. By contrast, the boost converter is allowed to operate during periods of no telemetry, when magnetic interference is not a concern, while obtaining the advantage of higher power efficiency.
