1. A continuous glucose sensor system comprising:

  • an implantable body comprising an electrode configured to measure a glucose level in a host;

    a membrane disposed over the electrode, wherein the membrane comprises a resistance domain configured to limit transport of glucose to the electrode and an enzyme to catalyze a reaction of glucose and oxygen as a co-reactant; and

    a sensor electronics unit operably connected to the electrode and configured to measure a current produced by the electrode with substantial linearity at glucose concentrations of up to about 400 mg/dL in a fluid with an oxygen concentration of less than about 0.6 mg/L.
