Abstract

In some aspects, an analyte sensor is provided for detecting an analyte concentration level in a bio-fluid sample. The analyte sensor may include one or more conductors received in a hollow portion of a hollow member. The first conductor may be made, at least in part, of a semiconductor material and an active region may be provided in contact with at least the first conductor. The analyte sensor may, in one aspect, include a lancet and an integrated sensor. Manufacturing methods and apparatus and systems utilizing the analyte sensors are provided, as are numerous other aspects.

First claim

The invention claimed is:

a carriage having at least two guides;
at least two analyte sensors each respectively received in one of the at least two guides wherein each analyte sensor includes
a member defining a hollow portion,
a sleeve secured in the hollow portion,
a first conductor secured in the sleeve,
a second conductor secured in the sleeve, and
an active region coupled to the first conductor and extending beyond the sleeve.

2. The analyte sensor system of claim 1 , further comprising a third conductor secured in the sleeve.

3. The analyte sensor system of claim 2 , wherein the third conductor includes a fill detection electrode.

4. The analyte sensor system of claim 1 , wherein the active region is within the hollow portion formed, at least in part, by the member and proximate to a first end of the member.

5. The analyte sensor system of claim 1 , further comprising a coded region.

6. The analyte sensor system of claim 1 , wherein the sensors are each independently adapted to sense an analyte comprising one or more of glucose, lactate, aspartate, glutamate, and alcohol.

7. The analyte sensor system of claim 1 , wherein the members of each sensor include a first end and an opposing second end, the first end of each member including a lancet point, and wherein the first conductors extend out of the second end of the members.

8. The analyte sensor system of claim 1 , wherein the members each include a hollow lancet including the hollow portion and a lancet point at an end thereof.

9. The analyte sensor system of claim 1 , wherein the sensors each further include a cavity defined by an inner wall of the member, an end of the member, and an end of the sleeve secured therein; and wherein the active region is positioned within the cavity.

10. The analyte sensor system of claim 1 , wherein the sensors each further include:
a lancet point formed on an end of the member;
a cavity formed within the hollow portion, proximate to an end of the sleeve secured in the hollow portion and proximate to an end of the first conductor; and
wherein the active region is positioned within the cavity.

11. An analyte sensor system, comprising:
a carriage having at least two guides;
at least two analyte sensors each respectively received in one of the at least two guides wherein each analyte sensor includes
a member defining a hollow portion,
a sleeve secured in the hollow portion,
a first conductor secured in the sleeve, and
an active region coupled to the first conductor and extending beyond the sleeve, wherein:
the first conductor includes a core of a conductive material and a cladding of a semiconductor material.

12. The analyte sensor system of claim 11 , wherein the conductive material of the core includes carbon and the semiconductor material of the cladding includes silicon carbide.

13. An analyte sensor system, comprising:
a carriage having at least two guides;
at least two analyte sensors each respectively received in one of the at least two guides wherein each analyte sensor includes

an active region coupled to the first conductor and extending beyond the sleeve, and
a fill detector.

14. The analyte sensor system of claim 1 , wherein the second conductor surrounds the first conductor.

15. An analyte sensor system, comprising:
a carriage having at least two parallel guides;
a lancet received in at least one of the guides; and
an analyte sensor received in another of the guides; wherein the analyte sensor comprises:
a member defining a hollow portion,
a sleeve secured in the hollow portion,
a first conductor secured in the sleeve, and
an active region coupled to the first conductor and extending beyond the sleeve.

16. An analyte sensor system, comprising:
a carriage having at least two parallel guides;
a lancet received in at least one of the guides; and
an analyte sensor received in another of the guides;
wherein the carriage is adapted to rotate the guide including the analyte sensor to a position previously occupied by the guide including the lancet.

17. An analyte sensor system, comprising:
a carriage having at least two parallel guides;
a lancet received in at least one of the guides;
an analyte sensor received in another of the guides; and
an actuator adapted to extend the lancet and the analyte sensor.

18. An analyte sensor system, comprising:
