Abstract

Low profile continuous analyte measurement systems and systems and methods for implantation within the skin of a patient are provided.

Claims

1. A continuous analyte measurement system, comprising:

a base unit configured for mounting on a skin surface;

an analyte sensor comprising two functional sides, a proximal portion configured for positioning within the base unit and a distal portion configured for insertion into the skin surface; and

a conductive member positionable within the base unit and in electrical contact with the two functional sides of analyte sensor.

2. The system of claim 1, wherein at least the proximal portion of the analyte sensor has a planar configuration and wherein the conductive member is mechanically and electrically coupled to the two functional sides of the proximal portion of the analyte sensor.

3. The system of claim 1, wherein the base unit is compressible on opposing sides at least about the conductive member.

4. The system of claim 1, further comprising a component for compressing the opposing ends of the conductive member.

5. The system of claim 4, wherein the component for compressing comprises flexures on opposing sides of the base unit about the conductive member.

6. The system of claim 4, wherein the component for compressing comprises a clamping fixture positionable on opposing sides of the base unit about the conductive member.

7. The system of claim 1, further comprising an alignment pin extending through the proximal portion of the analyte sensor.

8. The system of claim 1, wherein the base unit comprises a non-conductive compressible material.

9. The system of claim 8, wherein the non-conductive compressible material comprises silicone.

10. The system of claim 1, wherein the conductive connector comprises a conductive compressible material.

11. The system of claim 10, wherein the conductive compressible material comprises carbon-doped silicone.

12. The system of claim 1, further comprising a transmitter configured for mounting to the base unit in a low-profile manner, wherein the base unit further comprises a pair of receptacles for receiving a corresponding pair of conductive pins of the transmitter, wherein the conductive pins contact the conductive member when the transmitter is operatively mounted to the base unit.

13. The system of claim 12, wherein the transmitter mounts with the base unit in a side-by-side configuration.

14. The system of claim 12, wherein the transmitter mounts atop the base unit.

15. The system of claim 12, wherein the transmitter houses a battery.

16. The system of claim 12, wherein the base unit houses a battery.

17. The system of claim 16, wherein the base unit further comprise a second pair of receptacles for receiving a corresponding second pair of conductive pins of the transmitter, wherein the conductive pins contact the battery when the transmitter is operatively mounted to the base unit.

18. The system of claim 1, wherein the base unit comprises a cradle therein for receiving and holding the conductive member.

19. The system of claim 18, wherein the cradle compresses opposing ends of the conductive member when held within the cradle.

20. The system of claim 19, wherein the conductive member comprises a conductive core and an insulating shell covering the conductive core.

21. The system of claim 20, wherein the conductive member further comprises a non-conductive inner member within the conductive core, wherein the non-conductive inner member extends through an opening in the analyte sensor.

22. The system of claim 1, wherein the base unit comprises an adhesive bottom for adhering to the skin surface.

23. The system of claim 1, wherein the base unit comprises an opening therein through which the distal end of the analyte sensor extends.

24. The system of claim 1, wherein the distal end of the analyte sensor extends along a sidewall of the base unit.
