    摘要： A sensing electrode selection algorithm is disclosed for use with an implantable pulse generator having an electrode array. The algorithm automatically selects optimal sensing electrodes in the array to be used with a pre-determined stimulation therapy appropriate for the patient. The algorithm preferably senses stimulation artifacts using different sensing electrodes, and more specifically different sensing electrode pairs as is appropriate when differential sensing is used. The algorithm further preferably senses these stimulation artifacts with the patient placed in two or more postures. The algorithm processes the stimulation artifact features measured at the different sensing electrodes and at the different postures to automatically determine one or more sensing electrode pairs that best distinguishes the two or more postures given the prescribed stimulation therapy.

    摘要： An implantable control module for an electrical stimulation system includes a connector to couple to a lead or lead extension; an electronics housing coupled to the connector and having a first major surface, a second major surface, and at least one side surface; and an electronic subassembly disposed within the electronics housing. The electronics housing includes a first portion formed of a first conductive material and a second portion formed of a second conductive material. The second portion forms at least part of the first major surface and extends to form an adjacent region of the side surface or the second major surface. In some embodiments, the first conductive material has a resistivity that is no more than 50% of a resistivity of the second conductive material. In some embodiments, the first conductive material is titanium and the second conductive material is a titanium alloy.

    摘要： Receiver and digital demodulation circuitry for an external controller for communicating with an implantable medical device (IMD) is disclosed. A Digital Signal Processor (DSP) is used to sample received analog data transmitted from the IMD at a lower rate than would otherwise be required for the frequency components in the transmitted data by the Nyquist sampling criteria. To allow for this reduced sampling rate, the incoming data is shifted to a lower intermediate frequency using a switching circuit. The switching circuit receives a clock signal, which is preferably but not necessarily the same clock signal used by the DSP to sample the data. The switching circuit multiplies the received data with the clock signal to produce lower intermediate frequencies, which can then be adequately sampled at the DSP at the reduced sampling rate per the Nyquist sampling criteria.
