Abstract

The present invention provides an aspiration device that includes an outer cannula (16), a stylet (14), and an aspiration needle (80). The aspiration needle includes hollow cannula (82) and an aperture (93). The outer cannula (16) defines a distal tip (29) that is tapered to provide a distal cutting edge. The stylet (14) is designed to be inserted in the outer cannula (16). The stylet (14) also defines a sharp distal tip (30). The hollow cannula (82 ) designed to be inserted in the outer cannula (16). A distal end (91) of the hollow cannula (82) is closed and an aperture (93) is defined in a side of t he hollow cannula (82).

removing the stylet;
inserting an aspiration needle into the outer cannula;
creating a suction through the aspiration needle;
removing the aspiration needle;
further inserting the outer cannula into the medular cavity, thereby trapping bone marrow tissue within the outer cannula; and removing the bone marrow tissue from the patient.
34. The method for aspirating and sampling bone marrow tissue of claim 33 wherein the step of penetrating the bone cortex with the stylet and the outer cannula is achieved by penetrating the bone cortex with a sharp distal end of the stylet and a beveled distal end of the cannula.
