Abstract
A bone marrow access device includes a cannula and a sharp stylet removably positioned in the cannula. The cannula defines a distal opening at a distal tip and a side aperture in a side of the cannula, proximally from the distal opening. The stylet has a sharp distal tip and extends beyond the distal opening. A plug is receivable in the cannula distal to the side aperture to seal the distal opening when the stylet is removed. A method of accessing bone includes inserting the cannula and sharp stylet positioned in the cannula into bone; removing the sharp stylet from the cannula; pushing a plug through the cannula and distal to the side aperture to seal the distal opening of the cannula; and accessing the bone through the side aperture. Accessing the bone can include aspirating bone marrow, injecting a substance, or inserting an instrument into the bone.
