Patent ID: 7177684

Claim:
An implantable device for automatically monitoring and reporting patient physical activity, the device comprising: at least one implantable sensor operative to provide information related to patient movement; a processor in communication with the at least one implantable sensor, wherein the processor is operative to evaluate the information provided by the at least one sensor, automatically determine when the at least one sensor is indicating patient movement in excess of a threshold value, and automatically determine a maximum equivalent quantified activity during a determined interval; memory in communication with the sensor to receive and store data related to the patient's movement, including the maximum equivalent quantified activity; and a telemetry circuit in communication with the memory and operative to transmit internally determined data related to the patient's activity; wherein the sensor comprises an accelerometer; and wherein the device double integrates an acceleration signal from the sensor to determine a distance traveled by the patient so as to automatically determine the maximum equivalent quantified activity during the determined interval.
