Abstract: An intraosseous device, comprising a cannula through which life-saving fluids are transfusible into or out of bone marrow of a target bone when the cannula is penetrated into the target bone; a stylet which is engageable with the cannula; and means for causing penetration of the stylet and cannula, when mutually engaged, to a predefined depth ? within the target bone with respect to an outer surface of the target bone, the depth ? being irrespective of a thickness of tissue above the target bone.
