Claim Text:
1. A device for measuring a glucose concentration in a host, the device comprising: an implantable sensor operably connected to an electronic circuit and configured to continuously measure a signal indicative of a glucose concentration in a host for a period of time; and a membrane located over at least a portion of the sensor, wherein the membrane is configured to control a flux of oxygen and glucose, wherein the membrane comprises a product of a reaction of a compound comprising an isocyanate group with a compound comprising a hydroxyl group and/or a compound comprising an amine group; wherein the device during in vitro testing is capable of exhibiting, at a glucose concentration of 400 mg/dL, no more than a 10% drop in sensor output in response to a change of dissolved oxygen concentration from a pO
