Abstract
A processor controlled implantable cardiac stimulation device may be placed into a shelf mode for extending the shelf life of the device. The device includes a real time clock circuit, a watch dog timer circuit having a duty cycle, a telemetry circuit capable of operation in either an active mode or a standby mode, and ancillary circuits that sense cardiac activity and provides stimulation pulses to a heart. The device includes a power source for providing power to all of the circuits of the device and a shelf mode circuit that places the device into the shelf mode. The shelf mode circuit disables power to the ancillary circuits, decreases the duty cycle of the watch dog timer, sets the processor into a static state, and sets the telemetry circuit to the standby mode. The shelf mode circuit places the device into the shelf mode in response to shelf mode commands received by the telemetry circuit to set the device from an active powered mode to the shelf mode.
