Abstract
A needleless syringe particle delivery system is provided. The needleless syringe has an elongate nozzle that is connected at its upstream end to a sealed chamber. The sealed chamber contains gas at super-atmospheric pressure and particles of a therapeutic agent. Upon release of the gas from the sealed chamber, a flow is formed which entrains the particles and allows the particles to pass through the nozzle at supersonic speed for subsequent delivery to a target surface.
