Abstract

The present invention provides an electrode system and lead assembly for linking one or more electrodes to a physiological monitoring device. In general, the lead assembly comprises one or more lead sets and one or more lead links. The lead set generally comprises one or more leads each coupled at one end to a set connector, and at an other end, each coupled or adapted to be coupled to a respective electrode of the electrode system. The lead link generally comprises a link connector and one or more link leads operatively coupled thereto, each set lead being operatively coupleable to a corresponding link lead via direct or indirect operative coupling of the set connector and the link connector. Each link lead is further adapted to be coupled to one or more physiological monitoring devices, either by direct connection via a common or distinct connector(s) integral to the lead link, or by indirect connection via one or more additional connectors. The invention also provides for a lead set for linking multiple electrodes to a physiological monitoring device via an intermediary link, the lead set comprising multiple leads each adapted for operative coupling to a respective one the multiple electrodes and a connector adapted for connection to the intermediary link wherein each of said leads is operatively coupled to said connector and operatively coupleable to the monitoring device via connection of said connector to the intermediary link.
