Abstract: Devices for extracting bone marrow from a bone of a patient are disclosed. The device includes a housing defined in part by a cannula and a hollow needle disposed within the cannula. The hollow needle is movable axially relative to the cannula and extendable therefrom. The hollow needle is configured to aspirate bone marrow within a bone. A depth adjustment mechanism coupled to the hollow needle and the cannula is used to adjust the depth of the hollow needle relative to the cannula to control the distance of the needle within the bone. The device is attachable to an extraction device to extract bone marrow from the patient through the hollow needle. Methods of using these devices and methods of extracting bone marrow are also included.

Abstract: Methods and systems for collecting and processing bone marrow in a closed system are provided. The systems and methods include the use of a bone marrow aspiration needle and guide configured to puncture cortical bone. Tube assembly is in fluid flow communication with the bone marrow aspiration needle. A first syringe is in fluid flow communication with the tube assembly and the bone aspiration. A bone marrow aspirate collection container in fluid flow communication with the first syringe and the tube assembly. A second syringe is connected to the collection container, a bone marrow aspirate filter in fluid flow communication with the tube assembly to filter bone marrow aspirate from the first syringe into the collection container. At least one flow controller is configured to direct the flow of bone marrow aspirate between the aspiration needle, the first syringe and the collection container.
