A bone marrow access system includes a bone marrow access apparatus, a delivery tool that installs the apparatus in connection with a bone, instruments used while the apparatus is installed, and a removal tool to remove the apparatus. The apparatus includes a bone penetrating member having an internal channel having openings at proximal and distal ends, and a valve cap engaged with the bone penetrating member. The valve cap includes a valve having an opening having an open state in which the channel is not obstructed and a closed state preventing flow of material through the channel. The delivery tool includes a flange at one end and a drill bit extending beyond the flange. The flange fits in a seat in the bone penetrating member such that when the delivery tool is rotated while the flange is in the seat, the bone penetrating member is rotated into the bone.
