2. The apparatus of claim 1, the manual driver handle is T-shaped, substantially round-shaped, substantially oval-shaped, grip-shaped or having a hand ergonomic-design.

3. The apparatus of claim 1 wherein the drive shaft comprises a ratchet.

4. The apparatus of claim 1 wherein the connector is selected from a group consisting of a magnet, an O-ring mechanism and a ball and detent mechanism.

5. The apparatus of claim 1 wherein a second end of the connector comprises a threaded connection.

6. The apparatus of claim 1 wherein the penetrator comprises a hollow channel and a tip having one or more cutting surfaces.

7. The apparatus of claim 1 wherein the connector is releasably attached to the drive shaft.

8. The apparatus of claim 1 wherein the manual driver handle comprises at least one storage compartment.

9. The apparatus of claim 1 wherein the manual driver handle comprises at least one drive shaft.

10. The apparatus of claim 1 wherein the connector comprises a trocar.

11. An apparatus for penetrating bone marrow of a bone comprising:

a handle comprising a drive shaft;

a penetrator hub defined in part by a first end and a second end;
