Abstract:
1. A needle-free transdermal transport device for transferring a substance through a surface of a biological body, said device comprising: a reservoir for storing the substance; a nozzle in fluid communication with the reservoir; a controllable Lorentz-force electromagnetic actuator in communication with the reservoir, the actuator during operation responding to a received electrical input by generating a force proportional to the received input and variable responsive to variations in the received input, wherein the received input of a first type causes a needle-free injection of the substance from the reservoir into the biological body and the received input of a second type causes a needle-free withdrawal of a sample from the biological body into the transport device; a servo-controller for providing the electrical input into the actuator, the servo-controller dynamically controlling the force generated by the actuator during the injection; and an analyzer adapted to analyze the sample withdrawn from the body by the needle-free transdermal transport device, the servo-controller adapted to control the injection of the substance in response to an the analysis by the analyzer of the withdrawn sample.
