Patent ID: 8292808

Claim:
A method for sensing a physiological parameter comprising: implanting an implant unit in a non-vascular area of a body; allowing a foreign body capsule to form around the implant unit to surround the implant unit; providing a sensor lead, a first sensor element on the sensor lead for detecting a physiological parameter, the first sensor element configured to sense a first individual amount of the physiological parameter, and a second sensor element on the sensor lead for detecting the physiological parameter, the second sensor element configured to sense a second individual amount of the physiological parameter, wherein the sensor lead is separate but connectable to the implant unit; implanting the sensor lead with the first sensor element and second sensor element in a non-vascular area of the body and connecting the sensor lead to the implant unit; sensing the first individual amount and the second individual amount of the physiological parameter and generating a signal representing the first and second individual sensed amounts of the physiological parameter; and determining an overall amount of the physiological parameter by calculating a total statistical measurement of the first and second individual sensed amounts from the signals generated from the sensor elements.
