Abstract

Methods, device and system for providing a sensor insertion assembly including an inserter housing, an introducer including a body portion having a proximal end and a distal end and a shaft portion comprising a channel and a distal end, the shaft portion extending downwardly from an edge of the body portion, the shaft portion including a holding member disposed along a length of the channel, the holding member configured to substantially releasably retain a sensor, an on-body electronics unit, wherein the introducer is configured for insertion of the sensor through an aperture in the on-body electronics unit prior to insertion through skin and a drive mechanism included in the inserter housing and operatively coupled to the introducer, wherein the drive mechanism drives the introducer and retained sensor through the skin are provided.

Claims

1-21. -21. (canceled)

22. A direct-press insertion sensor device for measuring an analyte concentration, the device comprising:

an in vivo portion configured to be inserted through a skin of a host, the in vivo portion comprising at least one electrode and a membrane covering at least a portion of the at least one electrode; and

an ex vivo portion configured to support the sensor device on a surface of the skin of the host, the ex vivo portion comprising;

an upper surface comprising a flexible material configured to receive direct pressure from a user for insertion of the in vivo portion of the sensor device; and

a lower surface comprising an adhesive configured to adhere the ex vivo portion to the host'"'"'s skin.

23. The sensor device of claim 22, wherein the in vivo portion is configured to be inserted through the host'"'"'s skin without substantial buckling.

24. The sensor device of claim 22, wherein the at least one electrode comprises a working electrode and a reference electrode.

25. The sensor device of claim 22, wherein the ex vivo portion comprises a sensor electronics unit operatively and detachably connected to the in vivo portion.

26. The sensor device of claim 25, wherein the sensor electronics unit is configured to be located over a sensor insertion site.

27. The sensor device of claim 22, wherein the upper surface comprises an elastomeric material.

28. The sensor device of claim 22, wherein the in vivo portion has a substantially circular or oval shape.

29. The sensor device of claim 22, wherein the ex vivo portion has a domed shape prior to sensor insertion.

30. The sensor device of claim 22, wherein the direct pressure is from a thumb or finger of a user.

31. The sensor device of claim 22, wherein the upper surface is configured to remain in a collapsed state after the insertion of the in vivo portion.

32. The sensor device of claim 22, wherein the in vivo portion comprises a sensor body and a tissue piercing element.

33. The sensor device of claim 22, wherein the ex vivo portion comprises a guiding portion configured to provide guidance and support to the in vivo portion as the in vivo portion is inserted through the skin of the host.

34. The sensor device of claim 22, wherein the ex vivo portion comprises a lock to prevent withdrawal of the in vivo portion after insertion.

35. The sensor device of claim 22, wherein the ex vivo portion comprises a self-containing sterile field, wherein prior to sensor insertion the in vivo portion is hidden inside the self-containing field skin and cannot be seen.
