ABSTRACT:
An intraosseous and/or hard tissue drug delivery device and method is disclosed that perforates hard tissue and provides a drug delivery passage into underlying tissue. The device of the present invention includes a hollow drill bit and a stylet removably inserted into the hollow drill bit. The stylet keeps the bore of the hollow drill bit from plugging up during drilling. The stylet is removed after drilling to permit the operator to inject medication through the bore of the hollow drill bit.
