摘要： An improved transceiver circuit particularly useful in an inductively coupled wireless communication system such as an implantable medical device system is disclosed. The improved transceiver circuit is switchable to assume a serial L-C configuration in the transmit mode and a parallel L-C configuration in the receive mode, but does not require high voltage switches. A low-drive transmitter and a high-input-impedance receiver are used, which reduces power consumption in receive mode, while still maintaining good transmitter performance.

摘要： Improved power circuitry for charging a battery in an implantable medical device is disclosed. The improved power circuitry uses a DC-DC converter positioned between the rectifier and the battery in the implant to be charged, and operates to boost the voltage produced by the rectifier to a higher compliance voltage used to charge the battery. Because the rectifier can now produce a smaller DC voltage, the AC voltage preceding the rectifier (the coil voltage), can also be lessened. Lowering the coil voltage reduces the amount of heat generated by the coil, which reduces the overall heat generated by the implant during receipt of a magnetic charging field from an external charger during a charging session, which improves patient safety. Additionally, a reduced coil voltage means that the external charger can reduce the intensity of the magnetic charging field, which also reduces heat generated in the external charger during the charging session.
摘要翻译：公开了用于对可植入医疗装置中的电池充电的改进的电源电路。改进的电源电路使用位于植入物中的整流器和电池之间的DC-DC转换器来充电，并且操作以将由整流器产生的电压升高到用于对电池充电的较高顺应性电压。因为整流器现在可以产生较小的直流电压，整流器之前的交流电压（线圈电压）也可以减小。降低线圈电压可减少线圈产生的热量，从而减少了在充电期间从外部充电器接收到磁性充电场期间由植入物产生的总体热量，从而提高了患者的安全性。此外，减小的线圈电压意味着外部充电器可以减小磁充电场的强度，这也减少了充电阶段期间在外部充电器中产生的热量。

摘要： A method for configuring stimulation pulses in an implantable stimulator device having a plurality of electrodes is disclosed, which method is particularly useful in adjusting the electrodes by current steering during initialization of the device. In one aspect, a set of ideal pulses for patient therapy is determined, in which at least two of the ideal pulses are of the same polarity and are intended to be simultaneous applied to corresponding electrodes on the implantable stimulator device during an initial duration. These pulses are reconstructed into fractionalized pulses, each comprised of pulse portions. The fractionalized pulses are applied to the corresponding electrodes on the device during a final duration, but the pulse portions of the fractionalized pulses are not simultaneously applied during the final duration.

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.
摘要翻译：公开了一种用于植入式医疗装置（例如植入式脉冲发生器（IPG））的改进的架构。在一个实施例中，用于IPG的各种功能块被并入到信号集成电路（IC）中。每个功能块通过由通信协议管理的集中式总线彼此通信，并且如果需要，与其他片外设备通信。为了与总线进行通信并遵守协议，每个电路块包括与该协议相关的总线接口电路。由于每个块符合协议，任何给定的块都可以轻松修改或升级，而不影响其他块的设计，便于IPG电路的调试和升级。此外，由于集中式总线可以从集成电路中取出，所以额外的电路可以轻松地从芯片上添加到IPG中，以便对IPG进行主要的重新设计。

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.
摘要翻译：公开了用于在诸如IPG的可植入医疗设备和外部设备之间同步记录数据的时间基准的方法。 IPG将各种操作参数记录为数据，并将其与可能不准确的IPG时间戳和序列号相关联。周期性地，外部设备向IPG发送准确的真实时间数据，其与操作参数数据一起记录IPG时间戳和下一个序列号。 IPG然后通过组合数据日志中的时间戳命令数据序列和定时序列，并根据时间戳数据中显而易见的复位条件将该数据记录分成区域。针对区域内或区域间的各个区域计算表示真实时间和时间戳之间的关系的斜率，然后允许为数据序列计算真实时间估计，从而为记录数据。然后可以将数据序列的真实时间估计从IPG发送到外部设备以进行解释。

摘要： A method for controlling an implantable medical device is disclosed. In one embodiment, a voltage of a power source within the implantable medical device is monitored. If this voltage is above a first threshold, the implantable medical device enables the following functions: it listens for a first type of telemetry from a first external component; it listens for a second type of telemetry from an external charging component; and it provides stimulation to device electrodes using the power source. By contrast, if the power source voltage falls below the first threshold, the implant discontinues listening for the first type of telemetry from the first external component and discontinues providing stimulation to device electrodes using the power source, but continues to listen for the second type of telemetry.
