Abstract
Official abstract text for this publication.
The present disclosure provides a medical stimulation system including a plurality of implantable channels each operable to obtain a voltage signal from a designated area of body tissue. The medical stimulation system includes an impedance measurement device. The impedance measurement device includes a plurality of attenuators each coupled to a respective one of the channels. The attenuators are each operable to attenuate an amplitude of the voltage signal received from its respectively-coupled channel. The impedance measurement device includes a multiplexing component that receives the amplitude-attenuated voltage signals from each of the attenuators. The multiplexing component selectively outputs two of the amplitude-attenuated voltage signals. The impedance measurement device includes a differential amplifier that receives the two amplitude-attenuated voltage signals outputted from the multiplexing component as a differential input signal. The differential amplifier generates an amplifier output signal that includes an at least partially amplified version of the differential input signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A medical stimulation system, comprising: a plurality of implantable channels that are each operable to obtain a voltage signal from a designated area of a body tissue, wherein each of the channels is operable to obtain the voltage signal while simultaneously delivering electrical stimulation to the body tissue; and an impedance measurement device that includes: a plurality of attenuators that are each coupled to a respective one of the channels, each att…
