Abstract

Systems and methods for non-vascular sensor implantation and for accurately measuring a physiological parameter in areas of a body where amounts of the physiological parameter are heterogeneous. An implant unit (10) is implanted in an area of a body and a foreign body capsule is allowed to form around the area of the implant unit. 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 of the body. A subcutaneous area of the body may be tunneled to place the sensor. A plurality of 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 may be determined based on the sensed amounts.
