Monitoring electrode voltages in an implantable medical device system having daisy-chained electrode-driver integrated circuits

摘要

An implantable stimulator device, comprising: a first integrated circuit comprising a plurality of first electrodes configured to provide stimulation pulses to a patient's tissue via at least one lead; a second integrated circuit comprising a plurality of second electrodes configured to provide stimulation pulses to the patient's tissue via the at least one lead; and control circuitry configured to program any of the first and second electrodes as an anode for the stimulation pulses and configured to program a different any of the first and second electrodes as a cathode for the stimulation pulses, wherein the second integrated circuit comprises measurement circuitry configured to select and receive a voltage at the anode and a voltage at the cathode. 6911560_1 (GHMatters) P93070.AU.1 JEREMYR 17/09/2015 WO 2012/051015 PCT/US2O1 1/054876 uJ CD L(N 00 T i I I*zI D" I I I z *- IN (.
