Implantable sensor method and system
First Claim
1. 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.

Abstract
Systems and methods for non-vascular sensor implantation and for measuring physiological parameters in areas of a body where the physiological parameters are heterogeneous. An implant unit is implanted in an area of a body and a foreign body capsule is allowed to form around the implant unit area. A sensor may be directed into a body cavity such as, for example, the peritoneal space, subcutaneous tissues, the foreign body capsule, or other area. A subcutaneous area of the body may be tunneled for sensor placement. Spatially separated sensing elements may be used for detecting individual amounts of the physiological parameter. An overall amount of the physiological parameter may be determined by calculating a statistical measurement of the individual sensed amounts in the area. Another embodiment of the invention, a multi-analyte measuring device, may include a substrate having an electrode array on one side and an integrated circuit on another side.
