Abstract
A wearable apparatus for maintaining microneedles or other types of skin penetrating projections in contact with the interstitial fluid of the skin is disclosed. The apparatus has a skin contacting portion and a movable portion bearing the microneedles. The microneedles are initially in a retracted state, and are urged into the skin by movement of the movable portion along a non-linear, or arcuate path. The apparatus has a low profile when retained on the skin and is therefore less intrusive for extended wear applications such as continuous analyte monitoring and slow release drug delivery.

Apparatus for contacting one or more projections to the skin of a subject for an extended period, the apparatus comprising:
- one or more projecting portions, each configured to penetrate the skin;
- a skin contacting portion defining a skin contacting surface and one or more spaces allowing the one or more projecting portions to extend therethrough;
- a movable portion configured to move the one or more projecting portions from a first position behind the skin contacting surface to a second position proud of the skin contacting surface;
- and
- a retaining portion configured to, in use, retain the skin contacting surface in contact with the skin,
- wherein the movable portion is configured to move from the first position to the second position in a non-linear path.
