Implantable sensor method and system

A method for non-vascular implant of a sensor comprising:

• incising an area of a body large enough for inserting an implant unit;
• incising an area remote from a sensor location for inserting a sensor;
• directing the sensor into a body cavity;
• connecting the sensor to the implant unit;
• and
• inserting the implant unit into the body.

A method for non-vascular implant of a sensor comprising:

• incising an area of a body large enough for inserting an implant unit;
• creating a tunnel in subcutaneous tissue;
• directing the sensor through the tunnel;
• connecting the sensor to the implant unit;
• and
• inserting the implant unit into the body.

A method for spatially sensing a physiological parameter, comprising:

• implanting in an area of a body a plurality of spatially separated sensing elements for detecting a physiological parameter such that each of the sensing elements senses individual amounts of the physiological parameter within the area;
• generating a signal from each of the plurality of spatially separated sensing elements, the generated signals each representing an individual sensed amount of the physiological parameter;
• and
• determining an overall amount of the physiological parameter in the area by calculating a statistical measurement of the individual sensed amounts from the signals generated from a plurality of sensing elements.

A method for processing a signal representing a physiological parameter, comprising:

• implanting in a 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 signal representing a first individual sensed amount of the physiological parameter from one of the plurality of sensing elements, the first signal including a first amount of noise;
• detecting a second signal representing a second individual sensed amount of the physiological parameter from another of the plurality of sensing elements, the second signal including a second amount of noise;
• and
• determining a third signal representing an overall amount of the physiological parameter by calculating a statistical measurement of the first and second individual sensed amounts, the third signal having a third amount of noise less than both the first and second amounts of noise.

A multi-analyte measuring device comprising:

• a substrate;
• an electrode array on a first side of the substrate;
• and
• an integrated circuit on a second side of the substrate.
