The present invention relates generally to systems and methods for measuring an analyte in a host. More particularly, the present invention relates to systems and methods for transcutaneous measurement of glucose in a host.
What is claimed is: 1. A sensor system for measuring an analyte in a host, the system comprising: a sensor adapted for transcutaneous insertion into a host's skin; a housing adapted for placement adjacent to the host's skin; an electronics unit configured to be releasably attachable to the housing;
What is claimed is: 1. A sensor system for measuring an analyte in a host, the system comprising: a sensor adapted for transcutaneous insertion into a host's skin; a housing adapted for placement adjacent to the host's skin; an electronics unit configured to be releasably attachable to the housing; and an applicator configured to insert the sensor through the housing and into the skin of the host, wherein the applicator is adapted to releasably mate with the housing, and wherein the applicator is released from the housing in response to a connection of the electronics unit with the housing. 2. The system of claim 1, wherein the electronics unit is configured to slide-fit into the housing. 3. The system of claim 2, wherein the electronics unit is tapered to guide the slide-fit of the electronics unit into the housing. 4. The system of claim 1, wherein the electronics unit has an architecture configured to self-align with the housing. 5. The system of claim 1, further comprising a safety latch mechanism configured to keep the sensor from releasing from the applicator prior to release of the safety latch mechanism. 6. The system of claim 1, wherein the electronics unit releasably mated to the housing together comprise a subassembly, and wherein the subassembly has a volume of less than or equal to about 10 cm3. 7. The system of claim 6, wherein a major surface of the subassembly has a surface area of less than or equal to about 10 cm2, and wherein the major surface of the subassembly is configured to lie adjacent to the host's skin when in use. 8. A sensor system for measuring an analyte in a host, the system comprising: a sensor adapted for transcutaneous insertion into a host's skin; and a housing adapted for placement adjacent the host's skin; an electronics unit configured to mate with the housing; and an applicator configured to insert the sensor through the housing and into the skin of the host, wherein the applicator is releasably attached to the housing during sensor insertion, and wherein the electronics unit is configured to slide into the housing, thereby triggering release of the applicator from the housing. 9. The system of claim 8, wherein the applicator comprises a plunger configured to insert the sensor into the host's skin upon application of force to the applicator. 10. The system of claim 9, further comprising a safety latch mechanism is configured to keep the sensor from releasing from the applicator prior to release of the safety latch mechanism. 11. The system of claim 8, wherein the applicator is configured to insert the sensor into the patient at a depth of from about 0.1 mm to about 2 cm. 12. The system of claim 8, wherein the applicator is configured to insert the sensor into the patient at an angle between about 30�� and 60��. 13. The system of claim 8, wherein the system is sterilized. 14. The system of claim 8, wherein the housing and the electronics unit each comprise mutually engaging contacts configured to provide an electrical connection between the sensor and the electronics unit. 15. The system of claim 8, wherein the housing and the electronics unit each comprise mutually engaging contacts configured to enable detection of an attachment of the electronics unit to the housing. 16. The system of claim 8, wherein the housing and the electronics unit each comprise mutually engaging contacts configured to provide a value from the housing to the electronics unit, wherein the value is associated with information about the sensor. 17. The system of claim 16, wherein the information about the sensor is comprises sensitivity information, sensor identification information, and/or calibration information. 18. The system of claim 6, wherein the subassembly comprises first and second major surfaces when the electronics unit is attached to the housing, wherein the first and second major surfaces account for at least about 50% of the surface area of the device, and wherein surface area of each of the first and second major surfaces is less than or equal to about 10 cm2. 19. The system of claim 18, wherein the surface area of each of the first and second major surfaces is less than or equal to about 8 cm2. 20. The system of claim 18, wherein the surface area of each of the first and second major surfaces is less than or equal to about 6.5 cm2. 21. The system of claim 18, wherein the surface area of each of first and second major surfaces is less than or equal to about 5 cm. 22. The system of claim 18, wherein the surface area of each of the first and second major surfaces is less than or equal to about 4 cm2. 23. The system of claim 6, wherein the subassembly has a length, a width and a height, and wherein the length is less than or equal to about 40 mm. 24. The system of claim 6, wherein the subassembly has a length, a width and a height, and wherein the length is less than or equal to about 35 mm. 25. The system of claim 6, wherein the subassembly has a length, a width and a height, and wherein the width is less than or equal to about 20 mm. 26. The system of claim 6, wherein the subassembly has a length, a width and a height, and the width is less than or equal to about 18 mm. 27. The system of claim 6, wherein the subassembly has a length, a width and a height, and wherein the height is less than or equal to about 10 mm. 28. The system of claim 6, wherein the subassembly has a length, a width and a height, and wherein the height is less than or equal to about 9 mm. 29. The system of claim 6, wherein the subassembly has a volume of less than about 8 cm3. 30. The system of claim 6, wherein the subassembly has a volume of less than about 6 cm3. 31. The system of claim 6, wherein the subassembly has a volume of less than about 5 cm3. 32. The system of claim 6, wherein the subassembly has a volume of less than about 4 cm3.
