    A needle-free transdermal transport device (100) for non-axially transferring a substance across a surface of a biological body includes a reservoir (110) for holding a substance being transferred. A piston (105) is positioned within the device in communication with the reservoir (110) . An actuator (105) drives the piston (105) to expel the substance from the reservoir (110) . The reservoir (110) is in fluid communication with a nozzle (115) which includes at least one lateral aperture (145) through which the substance is expelled. Multiple lateral apertures (145) can result in a needle-freetransfer across a selectable surface area. The depth and direction of an injection can be controlled by the parameters of the nozzle (115) . By providing a selective depth and direction, it is possible to inject a substance into a targeted biological layer, such as a cleavage plane to further promote coverage. A control source can be used to activate the device (100) . The device (108) can also include an optional power source (125) .
