Patent ID: 8364238

Claim:
An electrode system, comprising: (a) a plurality of electrode modules, wherein each electrode module of the plurality of electrode modules defines a substantially central opening, wherein each electrode module further comprises a conductive ring, wherein each conductive ring is substantially coaxial with the substantially central opening of the associated electrode module; (b) a plurality of flexible connectors coupled with the plurality of electrode modules, wherein the flexible connectors comprise flexible circuitry configured to communicate signals from the electrode modules, wherein the flexible circuitry comprises traces formed on a flexible substrate; and (c) a plurality of sensors, wherein each sensor of the plurality of sensors is configured to removably couple with a corresponding one of the plurality of electrode modules, wherein the plurality of electrode modules are configured to sense evoked response potentials from a test subject, wherein each sensor is further configured to communicate sensed evoked response potentials to the associated electrode module, wherein each sensor comprises at least one outwardly extending conductive tab, wherein the outwardly extending conductive tab is configured to contact the conductive ring of the associated electrode module.
