Abstract:

A lead for delivering electrical signals to and/or receive electrical signals from a human heart that includes a solid inner conductor, and a fixation device having a titanium nitride coated surface and electrically coupled to the inner conductor. A steroid is applied to the titanium nitride surface of the fixation device, and at least one layer of insulation is positioned around the inner conductor. A conductive coil is positioned around and is insulated from the inner conductor, an electrode ring electrically coupled to the conductive coil is positioned around and is electrically isolated from the inner conductor, and an insulating spacer is positioned between and electrically isolates the ring electrode and the fixation device.
