Abstract
A universal infusion/aspiration cannula system includes a generally rounded tubular cannula member having a conduit or tubular portion provided with a rounded, partially, open, blunt insertion tip and a proximal end adaptable to standard fittings. The cannula alone allows for the blunt atraumatic dissection through intervening tissues and upon withdrawal, the simultaneous infusion of space filling substances, living tissues or hemostatic agents. A stilette member is provided which is operable within the cannula and the external dimensions of which approximate the internal dimensions of the cannula member wherein the stilette can be rotated or advanced and retracted as a saw to either amputate, cut or saw and grasp a biopsy specimen.
