Claim 15:
16. A medical device for assaying an analyte, the medical device comprising:
a sensor housing comprising a base surface having a tissue-facing surface profile defined thereon, the tissue-facing surface profile configured to be placed against a skin surface of a user; and
an analyte sensor at least partially arranged within the sensor housing, wherein a portion of the analyte sensor extends through the base surface and at least a portion of the tissue-facing surface profile, wherein the portion of the analyte sensor is configured for insertion into the tissue and in contact with a biological fluid of the user;
wherein the protrusion of the tissue-facing surface profile comprises:
a core extending from the base surface, wherein the core comprises a core material; and
