Patent ID: 7942845

Claim:
A needle-free injection device for delivering serial injections comprising: a body configured to house a plurality of systems; a delivery system adapted to deliver an injection, the delivery system comprising: an injectate assembly adapted to eject a volume of injectate responsive to application of an operative force to the injectate assembly, the injectate assembly having a nozzle assembly including a chamber and one or more ports, each terminating in an outlet orifice, the nozzle assembly further including a plunger selectively movable within the chamber; a drive assembly adapted to provide the operative force to move the plunger using energy from an energy supply; and a dosing assembly configured to transfer injectate from an injectate source to the injectate assembly, wherein a portion of energy available to the drive assembly urges injectate from the injectate source to the injectate assembly; and an actuation system adapted to actuate the delivery system for delivery of an injection, the actuation system comprising: a trigger assembly configured to restrict selectively operation of the drive assembly.
