Abstract
The present invention relates to a system for delivering and injecting an agent into a target site within the body without penetrating the tissue of the target site with anything other than the agent. The system comprises a nozzle assembly and a propulsion mechanism. The nozzle assembly comprises an ampule with a reservoir, having a reservoir orifice, for containing the agent; a dispersion fixture that has a dispersion orifice; and a channel in fluid communication between the reservoir orifice and the dispersion orifice. The propulsion mechanism is operatively coupled to the reservoir for propelling the agent from within the reservoir, through the reservoir orifice and the channel and the dispersion orifice, at a pressure sufficient to cause the agent to penetrate the target site without penetration of the target site with the dispersion fixture. Methods of using and making the system are also disclosed.
