Claim:
1. A method of determining an analyte concentration within a peritoneal fluid of a human subject, comprising: implanting an analyte sensor apparatus in the subject, the apparatus comprising a flexible sensing catheter and a housing, the catheter comprising, a lumen with a plurality of apertures and an exterior surface with an analyte sensor affixed thereto, the catheter comprising a proximal end attached to the housing, wherein the implanting step comprises positioning the sensing catheter freely within the peritoneal space and anchoring the housing at a subcutaneous site proximate the peritoneal space; contacting the analyte sensor with a peritoneal fluid sample outside the sensing catheter; sensing an analyte concentration in peritoneal fluid sample; and transducing the sensed analyte concentration into a transmittable electrical signal.
