Abstract
An apparatus and method for accessing the bone marrow of a human's sternum is provided. The apparatus includes a tissue penetrator configured to penetrate the sternum, a trigger mechanism configured to engage when the tissue penetrator contacts the sternum and a depth control mechanism operable to limit the penetration of the tissue penetrator into the sternum to a pre-selected depth.
Claims28
An apparatus for accessing the bone marrow inside a bone comprising:
- a penetrator assembly comprising a tissue penetrator and a luer lock connector, the tissue penetrator having a hollow cannula disposed in non-movably fixed relation to the luer lock connector;
- a driver operable to drive a portion of the tissue penetrator into the bone marrow;
- and
- a depth control mechanism operable to control the depth of penetration of the tissue penetrator into the bone and associated bone marrow, the depth control mechanism comprising an annular stop positioned to physically obstruct passage of the tissue penetrator.
An apparatus for accessing bone marrow inside a bone comprising:
- a cartridge with a tissue penetrator configured to penetrate the bone and associated marrow, and a luer lock connector, the tissue penetrator having a hollow cannula disposed in non-movably fixed relation to the luer lock connector;
- a depth control mechanism operable to limit penetration of the tissue penetrator into the bone and associated bone marrow, the depth control mechanism comprising an annular stop positioned to physically obstruct passage of the tissue penetrator;
- a flange operable to stabilize the tissue penetrator at a desirable level in the bone, the flange moveable along a vertical axis of the tissue penetrator;
- and
- a reusable handle configured to engage the tissue penetrator and drive the tissue penetrator into the bone marrow.
An apparatus for accessing the bone marrow inside a bone comprising:
- a handle;
- and
- a cartridge configured to attach to the handle, the cartridge comprising a tissue penetrator, a luer lock connector, and a depth control mechanism, the depth control mechanism comprising an annular stop positioned to physically obstruct passage of the tissue penetrator, the tissue penetrator having a hollow cannula disposed in non-movably fixed relation to the luer lock connector.
An apparatus for accessing the bone marrow inside a bone comprising:
- a penetrator assembly comprising a tissue penetrator configured to penetrate the bone marrow, and a luer lock connector, the tissue penetrator comprising an outer cannula and an inner trocar, the outer cannula disposed in non-movably fixed relation to the luer lock connector;
- a driver operable to drive the tissue penetrator into the bone marrow;
- a flange operable to stabilize the tissue penetrator after the cannula is inserted into the bone marrow, the flange moveable along a longitudinal axis of the tissue penetrator;
- and
- a depth control mechanism operable to limit penetration of the tissue penetrator into the bone and associated bone marrow, the depth control mechanism comprising an annular stop positioned to physically obstruct passage of the tissue penetrator.
