Architectures for an Implantable Medical Device System Having Daisy-Chained Electrode-Driver Integrated Circuits

摘要

An implantable stimulator device comprising a plurality of first electrodes and a plurality of second electrodes configured to provide stimulation to a patient's tissue is provided. The device comprises a first integrated circuit and a second integrated circuit identical in construction to the first integrated circuit. The first integrated circuit comprises a first stimulation circuitry block for controlling stimulation of the plurality of first electrodes, and a plurality of first functional blocks. The second integrated circuit comprises a second stimulation circuitry block identical to the first stimulation circuitry block for controlling stimulation of the plurality of second electrodes, and a plurality of second functional blocks identical to the plurality of first functional blocks. The plurality of first functional blocks are enabled, and the plurality of second functional blocks are disabled. 6670596_1 (GHMatters) P93088.AU.1 PAULA rr r LUj LU - C) LU LU r Ln LUj coo N D' C) ~
