(Brian David Thomson) The advantages of delivering injections via needle-free methods are numerous. However, conventional methods for needle-free injection lack sufficient control over depth of penetration and shape of injection. Thus, a needle-free injector was designed, constructed, and tested, using a controllable linear Lorentz-force actuator. This actuator allows rapid control of the injection pressure during injections. Using this device, precise control over delivery parameters can be achieved. In addition, several portable power systems for this injector were developed, allowing the energy-intensive needle-free injector to be used in the field. The injector design was tested for repeatability and use for both in-vitro and in-vivo testing on murine tissue using a bacterial collagenase.
