A bone aspiration needle is provided. The cannulated body can define at least a first aperture for aspirating bone marrow from a first region of an anatomy. The bone aspiration needle can also include a second aperture for aspirating bone marrow from a second region of the anatomy and a third aperture for aspirating bone marrow from a third region of the anatomy. The first aperture can be a distal most aperture and the third aperture can be a proximal most aperture. The first aperture can have a first area, the second aperture can have a second area, and the third aperture can have a third area. The second area can be greater than the first area and less than the third area so as to enable the aspiration of substantially equal amounts of bone marrow substantially simultaneously from each of the first aperture, second aperture and third aperture.
