Abstract
A temporary backup mechanism for electrical conduction within an implantable medical device (IMD) is provided. In an IMD such as lead or catheter having a cable conductor for conducting an electrical signal is provided with a safety cable for conducting an electrical signal if the primary cable conductor fails. In one embodiment, the conductor is a cable positioned adjacent to the safety cable so that the cable is in electrical contact with the conductor along various points on the conductor. In another embodiment, the conductor and cable are electrically isolated from one another except at proximal and distal ends where the two are mechanically coupled. In the latter embodiment, a change in impedance signals a potential conductor failure.
