A first aperture extends through the side wall of the outer cannula, and a second aperture extending through the end of the outer cannula. The needle also includes an inner cannula that is disposed within the outer cannula and includes a shaft portion having a bore extending therethrough. The inner cannula is selectively movable relative to the outer cannula between a first orientation and a second orientation. In the first orientation, communication is provided between the bore of the inner cannula and a first external region that is located adjacent to the second end of the outer cannula. In the second orientation, communication is provided between the bore of the inner cannula and a second external region that is located adjacent to the second end of the outer cannula.
