Abstract
An apparatus for delivering or withdrawing a fluid through at least one layer of the skin is provided. A device includes a body having a top face, a bottom face, a side edge and at least one channel. The bottom face includes a first surface area and a second surface area adjacent to and recessed at a first distance from the first surface area. The bottom face further includes at least one raised protrusion disposed on the second surface area. The protrusion has a height from the first surface greater than the first distance. At least one dermal-access member is provided in the protrusion and is in fluid communication with the channel to deliver or withdraw the fluid.
