Abstract

A cardiac electrode assembly includes an electrode lead with a plurality of electrical conductors in a common lead jacket. The electrical conductors include a primary conductor and at least a first secondary conductor. At a proximal end of the lead, the conductors terminate at a connector having a plurality of exposed electrical contacts. The contacts include a primary contact connected to the primary conductor and a secondary contact connected to the secondary conductor. A plurality of cardiac electrodes is mechanically connected to the distal end of the lead. The plurality includes a primary cardiac electrode and at least a secondary cardiac electrode (more preferably, at least two secondary cardiac electrodes) connected to one or more secondary conductors. In still preferred embodiments of the invention, multiple secondary conductors with separate leads in the common jacket are connected to the distal end of the common lead jacket.
