SUMMARY OF THE PRESENT INVENTION
Surgical tatooing instrumentation, as well as general tatooing instrumentation, heretofore involved the use of needles, either singular or in an array, mounted in pens or instruments which may be hand held for dipping of the exposed needles into an appropriate pigment solution which is to be applied sub-dermally to the skin of the subject. In accordance with the principles of the present invention, the pigment solution is delivered to the needles by new and improved cartridge in which the pigment solution is contained for continuous delivery from within the instrument to the exposed needle points.
