Abstract
A needleless injection system is provided to deliver therapeutic fluids to an internal treatment site in a patient, where the system is pressurized and is capable of compensating for differences in injection media viscosity and mechanical system characteristics. In one aspect, a needleless therapeutic fluid injection system is provided that includes modular, interchangeable components. In particular, the system includes a console that generally includes the electronic and/or hydraulic control components for the system, an injection chamber, and a shaft or catheter tube.
