1. A method for continuously measuring an analyte in an artery of a host in vivo, the method comprising:
- coupling a continuous analyte sensor with an arterial catheter system applied to a host, wherein the sensor is configured to generate an analyte-related signal associated with an analyte in a sample, and wherein the arterial catheter system comprises an arterial catheter, an infusion fluid, and a pressure system configured to perform at least one of increasing an amount of pressure applied to the infusion fluid and reducing an amount of pressure applied to the infusion fluid;
reducing the amount of pressure applied to the infusion fluid, such that a sample of arterial blood contacts the sensor; and
generating the analyte-related signal with the sensor.

13. A system for continuously measuring an analyte in an artery of a host in vivo, the system comprising:
-
an arterial infusion system configured and arranged to meter at least one of flow of a fluid into an artery of a host and flow of a fluid out of an artery of a host, the arterial infusion system comprising an arterial catheter, an infusion fluid, and a pressure system configured to perform at least one of increasing an amount of pressure applied to the infusion fluid and reducing an amount of pressure applied to the infusion fluid, wherein when the infusion system is applied to the host, the pressure system is further configured to infuse the infusion fluid, withdraw a blood sample, and reinfuse the withdrawn blood sample into the host; and a continuous analyte sensor configured to couple with the arterial infusion system, configured to contact a sample of the host, and configured to generate a first signal associated with an analyte in the sample. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
