Fastening device for acquiring bone marrow aspirate

A cannulated fastener for surgical procedures comprising:

• said cannulated fastener (100) including a first end (10), a sidewall, and a cannula bore, said first end (10) being closed and including a drill point (14), said drill point (14) including a center point (28) positioned along a longitudinal centerline of said cannulated fastener (100), a tapered lead (16), said tapered lead (16) being smooth and free from cutting surfaces and extending between said drill point (14) and a holding surface (11), said tapered lead constructed and arranged to expand and size a diameter of a hole in a bone formed by the drill point (14) by smoothing or burnishing sidewalls of the hole, said holding surface constructed and arranged to cooperate with the sidewalls of the hole to compressively form a portion of the sidewalls of the hole to secure the cannulated fastener to the bone and a directional aperture (18) extending through the sidewall of said cannulated fastener (100) to provide a fluid connection to the cannula bore (36) of said cannulated fastener (100);
• a second end (20) including a connector (22) for connecting to a source of vacuum, whereby vacuum is applied to said cannula bore (36) and said directional aperture (18) for drawing bone marrow aspirate from a hole in a bone created by said cannulated fastener (100).
