Transcutaneous analyte sensor
First Claim
Patent Images
1. A transcutaneous analyte sensor assembly, the assembly comprising:
- a housing adapted for mounting on a skin of a host, wherein the housing comprises a first portion adapted for mounting on the skin of the host and a second portion that angularly articulates relative to the first portion between an insertion position and a sensing position such that the insertion position and the sensing position are not the same;
a sensor configured to measure a level of an analyte in the host, wherein the sensor extends from the housing and is adapted to be inserted through the skin of the host; and
an applicator configured to releasably attach to the housing, wherein the applicator is configured to maintain the second portion at a predetermined angle of insertion relative to the first portion in the insertion position, and wherein the second portion receives and guides insertion of the sensor into the host, wherein the insertion position allows insertion of the sensor through the housing and into the host'"'"'s tissue, and wherein the sensing position maintains the sensor within the host during the measurement of the level of the analyte in the host.

10. A transcutaneous analyte sensor assembly, the assembly comprising:
-
a housing adapted for mounting on a skin of a host, wherein the housing comprises a first portion for mounting on the skin of the host and a second portion configured to articulate relative to the first portion between a first position and a second position; a sensor configured to measure a level of an analyte in the host, wherein the sensor, received by the second portion, extends from the housing and is adapted to be inserted through the skin of the host; and an applicator configured to releasably attach to the housing, wherein the sensor and the housing are configured such that after insertion of the sensor through the skin of the host and release of the applicator from the housing, articulation of the housing between the first position and the second position causes the sensor to bend. - View Dependent Claims (11, 12, 13)

14. A transcutaneous analyte sensor assembly, the assembly comprising:
-
a housing adapted for mounting on a skin of a host, wherein the housing comprises one or more electrical contacts; a sensor configured to measure a level of an analyte in the host, wherein the sensor extends through the housing and is adapted to be inserted in the skin of the host; and an applicator comprising an introducer configured to guide insertion of the sensor through the housing and into the skin of the host, wherein after sensor insertion, the applicator is configured to subsequently remove the introducer from the sensor, and wherein the assembly is configured such that removal of the introducer from the sensor causes the sensor to make electrical contact with the one or more electrical contacts of the housing. - View Dependent Claims (15, 16, 17, 18)
