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.
1. A transcutaneous system for measuring an analyte concentration in a host, the system comprising: a sensor adapted for transcutaneous insertion through a skin of a host;a mounting unit adapted for placement adjacent to the skin of the host;an electronics unit configured to be releasably attachable
1. A transcutaneous system for measuring an analyte concentration in a host, the system comprising: a sensor adapted for transcutaneous insertion through a skin of a host;a mounting unit adapted for placement adjacent to the skin of the host;an electronics unit configured to be releasably attachable to the mounting unit, the electronics unit electrically coupled to the sensor when releasably attached to the mounting unit, wherein the mounting unit is configured such that the electronics unit is located over an exit site of the sensor when the sensor is inserted through the skin of the host; andan applicator comprising a needle comprising a lumen, wherein the needle is configured to receive the sensor, a plunger subassembly configured to push the needle and the sensor through the mounting unit and subsequently retract the needle into the applicator, and a component configured to maintain the sensor at a predetermined depth in the host upon retraction of the needle into the applicator, wherein the applicator must be removed prior to releasably attaching the electronics unit to the mounting unit. 2. The system of claim 1, wherein the needle surrounds the sensor. 3. The system of claim 1, wherein the plunger irreversibly retracts the needle into the applicator. 4. The system of claim 1, wherein the system is configured to insert the sensor through the skin with a depth to about 2 cm. 5. The system of claim 1, wherein the system is configured to insert the sensor through the skin with a depth of from about 0.1 mm to about 2 cm. 6. The system of claim 1, wherein the component is configured to maintain the sensor at the predetermined depth in the host upon irreversible retraction of the needle into the applicator. 7. The system of claim 1, wherein the applicator is configured to insert the sensor in response to an activation of an automated mechanism. 8. The system of claim 1, wherein the applicator is configured to insert the sensor in response to a manual force applied to the applicator by a user. 9. The system of claim 1, wherein the needle is designed without a slot. 10. The system of claim 1, wherein the needle is designed without multiple components. 11. The system of claim 1, wherein the needle comprises a slot cut in the needle. 12. A transcutaneous system for measuring an analyte concentration in a host, the system comprising: a sensor adapted for transcutaneous placement through a skin of a host;a housing adapted for placement adjacent to the skin of the host, wherein the housing comprises at least one electrical contact therein for providing an electrical connection between the sensor and sensor electronics; andan applicator configured for inserting the sensor through the housing and into the skin of the host, wherein the insertion of the sensor disposes the sensor adjacent to the electrical contact or within the electrical contact,wherein the system is configured so that the sensor exits the housing at a location substantially closer to the center of the housing than the edges thereof when the sensor is transcutaneously placed in the host. 13. The system of claim 12, wherein the electrical contact comprises an elastomeric contact and wherein the sensor is configured to extend through the elastomeric contact. 14. The system of claim 12, comprising two electrical contacts. 15. An applicator system for inserting a transcutaneous sensor into a host, the applicator comprising: a sensor configured for transcutaneous placement through a skin of a host;a needle comprising a lumen, wherein the needle is configured for inserting the sensor into the host, wherein the sensor is disposed in the needle prior to insertion into the host;a housing adapted for placement adjacent to the skin of the host;an electronics unit releasably attachable to the housing, the electronics unit configured to electrically couple to the sensor and generate analyte concentration data using the sensor; andan applicator configured for inserting the needle and the sensor into the skin of the host and subsequently retracting the needle into the applicator,wherein the needle and the sensor are disposed within the applicator prior to insertion of the sensor,wherein the applicator comprises a push subassembly configured to maintain the sensor at an insertion depth in the host when the needle is retracted into the applicator, andwherein the applicator is configured such that it must be released from the housing in order to allow the electronics unit to be attached to the housing. 16. The system of claim 15, wherein the sensor is disposed in the lumen of the needle. 17. The system of claim 15, wherein the sensor is disposed within the lumen of the needle. 18. The system of claim 15, wherein the sensor is disposed within the needle. 19. The system of claim 15, wherein the applicator is configured to insert the sensor in response to an activation of an automated mechanism. 20. The system of claim 15, wherein the applicator is configured to insert the sensor in response to a manual force applied to the applicator by a user. 21. The system of claim 15, wherein of the applicator is configured to release from the housing after the sensor has been transcutaneously inserted into the host. 22. The system of claim 15, wherein the applicator is releasably attached to the housing prior to sensor insertion and during sensor insertion. 23. The system of claim 15, wherein the needle is designed without a slot. 24. The system of claim 15, wherein the needle is designed without multiple components. 25. The system of claim 15, wherein the needle comprises a slot cut in the needle. 26. A transcutaneous system for measuring an analyte concentration in a host, the system comprising: a sensor adapted for transcutaneous insertion through a skin of a host;a mounting unit adapted for placement adjacent to the skin of the host;an electronics unit configured to be releasably attachable to the mounting unit, the electronics unit electrically coupled to the sensor when releasably attached to the mounting unit, wherein the mounting unit is configured such that the electronics unit is located over an exit site of the sensor when the sensor is inserted through the skin of the host; andan applicator comprising a needle configured to receive the sensor, a plunger subassembly configured to push the needle and the sensor through the mounting unit and subsequently retract the needle into the applicator, and a component configured to maintain the sensor at a predetermined depth in the host upon retraction of the needle into the applicator, wherein the applicator must be removed prior to releasably attaching the electronics unit to the mounting unit, and wherein the component comprises a push rod configured to contact a portion of the sensor while the needle is being retracted into the applicator. 27. The system of claim 26, wherein the needle comprises a lumen. 28. The system of claim 27, wherein the sensor is disposed in the lumen of the needle. 29. The system of claim 27, wherein the sensor is disposed within the lumen of the needle. 30. The system of claim 26, wherein the sensor is disposed within the needle. 31. The system of claim 26, wherein the applicator is configured to insert the sensor in response to an activation of an automated mechanism. 32. The system of claim 26, wherein the applicator is configured to insert the sensor in response to a manual force applied to the applicator by a user. 33. The system of claim 26, wherein of the applicator is configured to release from the housing after the sensor has been transcutaneously inserted into the host. 34. The system of claim 26, wherein the applicator is releasably attached to the housing prior to sensor insertion and during sensor insertion.
