Abstract
A transdermal transport device includes a reservoir for holding a formulation of an active principle, and one or more needles. Each needle has a bore through which the formulation is transported between the reservoir and a biological body, and has an end portion that is substantially aligned in a plane parallel to a surface of the biological body when the device is placed on the surface. The device also includes a vacuum generator which creates a suction to draw a portion of the surface beyond the plane of the end portions to enable the end portions to penetrate the portion of the surface as the needles are translated along an axis that is substantially parallel to the plane.
