Method and apparatus for extracting bone marrow

Apparatus for extracting bone material from an extraction site, comprising:

• a housing defining a cavity and a passageway for transporting bone material to a collection device, the passageway having a distal end, in communication with a first end of a suction tube, and a proximal end;
• the housing further defining a second passageway for passing irrigation fluid to the extraction site, the apparatus further comprising a source of irrigation fluid in fluid communication with the second passage;
• a flexible shaft with a proximal end disposed in the cavity and a distal end extending beyond the cavity;
• an abrading head attached to the distal end of the shaft;
• a conduit extending through the shaft and abrading head, the conduit fluidly communicating with the passageway;
• and
• an actuator coupled to the proximal end of the shaft, wherein the shaft is free to deflect radially with respect to a connection to the actuator.
