Abstract
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.
Claims21
A transcutaneous analyte sensor assembly, the assembly comprising:
- a housing comprising a first side adapted for mounting on a skin of a host and a second side located substantially opposite the first side, wherein the housing comprises one or more electrical contacts;
- a sensor electronics unit comprising one or more electrical contacts, wherein the sensor electronics unit is configured to releasably mate with the second side of the housing such that the one or more electrical contacts of the housing electrically connect with the one or more electrical contacts of the sensor electronics unit;
- and
- a sensor configured to continuously and/or intermittently measure a level of an analyte in a tissue of the host, wherein the sensor comprises one or more electrical contact points configured to electrically connect to the electrical contacts of the sensor electronics unit via the electrical contacts of the housing when the sensor electronics unit is mated to the housing, wherein the housing is configured to continuously support the sensor within the tissue of the host during a time period of continuous or intermittent measurement.

A transcutaneous analyte sensor assembly, the assembly comprising:
- a housing adapted for mounting on a skin of a host;
- a sensor comprising at least two electrodes, wherein the sensor is configured to extend through the housing;
- sensor electronics configured to electrically connect with the at least two electrodes;
- at least two electrical contacts aligned longitudinally along and extending circumferentially around a central longitudinal axis, wherein the at least two electrical contacts are configured to provide an electrical connection between the at least two electrodes and the sensor electronics;
- and
- a needle comprising a lumen, wherein the sensor is dimensioned and arranged such that the sensor has a width that fits within the lumen of the needle.
3 more elements
A transcutaneous analyte sensor assembly, the assembly comprising:
- a housing adapted for mounting on a skin of a host;
- sensor electronics associated with the housing;
- a sensor configured to measure a level of an analyte in the host, wherein the sensor comprises at least two electrode materials, wherein the sensor is configured to operably connect to the sensor electronics;
- and
- at least two electrical contacts aligned along a single longitudinal axis of the sensor wherein the electrode materials are configured to penetrate through the at least two electrical contacts to enable the operable connection of the sensor to the sensor electronics.
