1. A bone marrow access apparatus, comprising:
a bone penetrating member having an internal channel having an opening at a proximal end and an opening at a distal end; and
a cap engaged with the bone penetrating member, the cap defining an interior cavity in which part of the bone penetrating member is situated,
wherein:
the bone penetrating member comprises an axially extending insertion portion and a head portion having a larger cross-sectional area than the insertion portion,
the head portion has a distally-facing bottom surface adjacent the insertion portion and a step peripherally outward of the bottom surface and providing an outer peripheral surface of the head portion with an indentation, the step being adjacent to the bottom surface, recessed proximally with respect to the bottom surface, and having a surface that faces distally,
the cap comprises a peripheral wall, an upper wall coupled to an upper edge region of the peripheral wall, and a lower rim coupled to a lower edge region of the peripheral wall, the interior cavity being defined by the upper wall, the peripheral wall, and the lower rim, and
the lower rim extends inward from the peripheral wall into the indentation to thereby secure the cap to the bone penetrating member.
