Abstract

A low-power circuit measures the impedance between the case and any electrode (a monopolar measurement), or the impedance between any two electrodes (a bipolar measurement) of an implantable neurostimulator, such as a spinal cord stimulation (SCS) device or a deep brain stimulation (DBS) device. Lead impedance information obtained using the circuit may be used by a clinician to assess lead integrity or quality of lead placement -- parameters that are critically important for correct or optimized operation of a SCS or DBS device.
