Patent ID: 7736309

Claim:
A method for processing a signal representing a physiological parameter, the method comprising: implanting in a body a computing element; implanting in the body a plurality of spatially separated sensing elements, each of the sensing elements for sensing individual amounts of the physiological parameter in the body; detecting a first time-variant signal representing a first individual sensed amount of the physiological parameter from one of the plurality of sensing elements, the first time-variant signal including a first amount of noise; detecting a second time-variant signal representing a second individual sensed amount of the physiological parameter from another of the plurality of sensing elements, the second time-variant signal including a second amount of noise; and determining, via the computing element, a third time-variant signal representing an overall amount of the physiological parameter by calculating a statistical measurement of the first and second individual sensed amounts, the third time-variant signal having a third amount of noise less than both the first and second amounts of noise; wherein the first and second signals are detected substantially simultaneously and wherein said computing element and said plurality of spatially separated sensing elements are located at different sites within the body; and wherein implanting the computing element and the sensing elements comprises: implanting an implant unit containing the computing element in the body; allowing a foreign body capsule to form around the implant unit to surround the implant unit; and directing the sensing elements into the foreign body capsule.
