A new architecture is disclosed for an IPG having a master and slave electrode driver integrated circuits (ICs). The electrode outputs on the ICs are wired together. Each IC can be programmed to provide pulses with different frequencies. Active timing channels in master and slave ICs are programmed to provide the desired pulses, while shadow timing channels in the master and slave are programmed with the timing data from the active timing channels in the other IC so that each chip knows when the other is providing a pulse, so that each chip can disable its recovery circuitry so as not to defeat those pulses. In the event of pulse overlap at a given electrode, the currents provided by each chip will add at the affected electrode. Compliance voltage generation is dictated by an algorithm to find an optimal compliance voltage even during periods when pulses are overlapping.

Disclosed is a new architecture for an IPG having a master and slave electrode driver integrated circuits. The electrode outputs on the integrated circuits are wired together. Each integrated circuit can be programmed to provide pulses with different frequencies. Active timing channels in each of the master and slave integrated circuits are programmed to provide the desired pulses, while shadow timing channels in the master and slave are programmed with the timing data from the active timing channels in the other integrated circuit so that each chip knows when the other is providing a pulse, so that each chip can disable its recovery circuitry so as not to defeat those pulses. In the event of pulse overlap at a given electrode, the currents provided by each chip will add at the affected electrode. Compliance voltage generation is dictated by an algorithm to find an optimal compliance voltage even during periods when pulses are overlapping.

An electrical stimulation system provides stimulation therapy to a patient. The system includes a neurostimulation lead that contacts patient tissue and couples with an implantable stimulation device, such as an implantable pulse generator, that receives stimulation parameters for providing stimulation therapy to a patient. The implantable stimulation device includes a header with a plurality of connector assemblies that receive an end of the neurostimulation lead, and a case containing a charging coil and a telemetry coil coupled to programming circuitry on a printed circuit board, which is in turn coupled to the connector assemblies via a feedthrough assembly. The telemetry coil receives data from an external programmer and transmits the data to the programming circuitry, which in turn uses the data to communicate to the connector assemblies and the neurostimulation lead to provide stimulation therapy to a patient.

Implantable medical device for providing stimulation therapy

One aspect provides a capacitor feedthrough assembly having an electrically conductive member dimensioned to extend at least partially through a feedthrough hole of a case of the capacitor, the conductive member having a passage therethrough.

Flat capacitor for an implantable medical device

Designs and methods of construction for an implantable medical device employ an internal support structure. The single-piece support structure holds various electronic components such as a communication coil and a circuit board, and further is affixed to a battery, thus providing a subassembly that is mechanically robust. The support structure further provides electrical isolation between these and other components. A method of construction allows for the subassembly to be adhered to a case of the implantable medical device at the support structure, and possibly also at the battery, without electrically shorting the battery to the case.

Construction for an implantable medical device having a battery affixed to the case

Designs and methods of construction for a printed circuit board (PCB) in an implantable pulse generator (IPG) are disclosed which facilitate IPG PCB testing while also providing for protection of IPG circuitry in a simple and cost effective manner. The IPG PCB is formed as part of a larger test PCB, which includes an extender portion with traces routing nodes of interest in the IPG PCB to an edge connector. IPG electronics are mounted or soldered to the IPG PCB, and then such electronics are tested via the edge connector. The IPG PCB is then singulated from the extender portion in a manner leaving one or more PCB tabs at the severed edge of the PCB. The PCB tab(s) extend from the severed edge, and create an offset distance preventing traces severed and now exposed at the severed edge from contacting and potentially shorting to conductive structures in the IPG.

Method of fabricating and testing a circuit board

A control module for providing electrical stimulation of patient tissue includes a header disposed over an electrical interface. A connector assembly retainer is disposed in the header and coupled to the electrical interface. The connector assembly retainer includes a plurality of channels and a plurality of apertures defined at one end of the connector assembly retainer. Each of a plurality of connector assemblies is disposed in a different one of the plurality of channels of the connector assembly retainer. Each of the plurality of connector assemblies is configured and arranged for receiving a portion of a lead or lead extension and coupling the lead or lead extension to the electronic subassembly.
