Abstract
A transdermal transport device includes a reservoir for holding a formulation of an active principle, and a needle with a bore extending along the length of the needle from a first end of the needle to a second end of the needle. The second end is substantially aligned to a plane parallel to a body surface of a biological body when the device is placed on the body surface. The device also includes an actuator which pumps the formulation through the bore of the needle between a target area of the body and the reservoir.
