ABSTRACT:
The present invention provides prefillable syringes and injectors for use therewith that expand and/or facilitate a variety of medical procedures involving the injection of a liquid medium. In several embodiments, the present syringes and injectors enable the use of current syringe materials at higher pressures than previously attainable or the use of other materials not previously usable with current high pressure-syringe and injector designs. In one embodiment, a syringe comprises an elongated cylindrical main body having a first pair and a second pair of mounting flanges encompassing collectively an arcuate length equal to at least approximately 180.degree. of the circumference of the rear portion of the cylindrical main body for releasably mounting the syringe in a desired position relative to the front wall of the injector housing. Injectors for use with such syringes comprise a housing having a front wall and a retainer on the front wall which cooperates with the first and second pairs of mounting flanges of the syringe to releasably mount the syringe on the injector.
