ANALYTE SENSOR
Systems and methods of use for continuous analyte measurement of a host's vascular system are provided. In some embodiments, a continuous glucose measurement system includes a vascular access device, a sensor and sensor electronics, the system being configured for insertion into a host's peripheral vein or artery.
1 . A system for measuring glucose in a host and delivering medication to the host, the system comprising:
a catheter configured for insertion into a host and configured to deliver medication to the host, wherein the catheter comprises an exterior surface;
a continuous glucose sensor disposed at least partially on the exterior surface of the catheter, wherein the continuous glucose sensor is configured to generate sensor data indicative of glucose concentration; and
sensor electronics operatively connected to the continuous glucose sensor, wherein the sensor electronics are configured to determine a glucose concentration.
2 . The system of claim 1 , wherein the continuous glucose sensor is integrally formed on the exterior surface of the catheter.
3 . The system of claim 1 , wherein the continuous glucose sensor is electroplated onto the exterior surface of the catheter.
4 . The system of claim 1 , wherein the continuous glucose sensor comprises a working electrode and a membrane system covering at least a portion of the working electrode.
5 . The system of claim 1 , wherein the working electrode comprises an exposed electroactive surface.
6 . The system of claim 1 , wherein the catheter is configured to be operatively connected to an infusion pump.
7 . The system of claim 1 , wherein in response to sensor data received from the continuous glucose sensor, the sensor electronics are configured to communicate a therapy recommendation to the infusion pump, wherein the therapy recommendation comprises information relating to insulin amount.
8 . The system of claim 1 , wherein the continuous glucose sensor is configured to be used subcutaneously.
9 . The system of claim 1 , wherein the sensor electronics are configured to substantially continuously determine the glucose concentration.
