1. An implantable medical device comprising:
- signal generation circuitry that delivers power to a sensor carried by an implantable medical lead that is connected to the implantable medical device, wherein the lead includes at least one conductor that is coupled to an electrode and the sensor, and the signal generation circuitry delivers power to the sensor via the conductor; and
a processor to control delivery of power by the signal generation circuitry, communicate with the sensor via the conductor, and suspend a function of the implantable medical device during at least one of delivery of power to the sensor or communication with the sensor.

Abstract
An implantable medical lead includes a device, such as a physiological sensor, that is coupled to one or more stimulation/sensing sensing conductors within the lead. When the implantable medical lead is coupled to an implantable medical device, the device carried by the lead both receives power from, and communicates with the implantable medical device via the one or more stimulation/sensing sensing conductors. Each of the one or more stimulation/sensing sensing conductors is also coupled to an electrode that is exposed to body tissue.
