1. An assembly for analyte monitoring in a host, the assembly comprising:
- a transcutaneous analyte sensor having an in vivo portion and an ex vivo portion, wherein the transcutaneous analyte sensor is operably connectable to sensor electronics configured for detecting a signal from the transcutaneous analyte sensor, wherein the signal is indicative of an analyte concentration in the host;
at least one electrical contact configured to operably connect the ex vivo portion of the sensor to the sensor electronics;
a base configured for placement adjacent to the host'"'"'s skin;
an elastomeric sealing member in contact with the ex vivo portion of the sensor and at least partially surrounding the at least one electrical contact, wherein the elastomeric sealing member is configured to seal the at least one electrical contact from moisture, wherein the elastomeric sealing member is held on the base by mating mechanical structures on the base and on the elastomeric sealing member.
