Patent ID: 7424318

Claim:
A glucose sensor system configured for insertion into a host for measuring a glucose concentration in the host, the system comprising: a sensor comprising a first working electrode and a second working electrode, wherein the first working electrode is configured to generate a first signal associated with glucose and non-glucose related electroactive compounds, the glucose and non-glucose related electroactive compounds having a first oxidation potential; wherein the non-glucose related electroactive compounds with an oxidation potential that substantially overlaps with the first oxidation potential, and wherein the first working electrode and the second working electrode are configured and arranged about a central longitudinal axis along an overlapping length of the sensor such that the central longitudinal axis passes through each of the working electrodes; and electronics operably connected to the first working electrode and the second working electrode and configured to process the first signal and the second signal to generate a glucose concentration substantially without signal contribution due to in vivo mechanical factors.
