Bone Material Harvesting Device Having Radially Expandable And Retractable Shaft

A reamer assembly for extraction of bone and/or cellular material from a patient, the reamer assembly, comprising:

• a shaft defining a distal end arranged to receive a reamer head;
• and
• an outer tube at least partially surrounding the shaft and coupled to the shaft, the outer tube having a deformable section moveable between an elongated condition during reaming and a radially expanded condition for extracting the bone and/or cellular material from the patient,
• wherein movement of the outer tube relative to the shaft in a distal direction transitions the deformable section from the elongated condition to the radially expanded condition, and movement of the outer tube relative to the shaft in a proximal direction transitions the deformable section from the radially expanded condition to the elongated condition.

A method of collecting bone and/or cellular material during a harvesting procedure, the method, comprising:

• (a) reaming a canal of a bone to generate bone and/or cellular material using a harvesting device including a shaft, an outer tube at least partially surrounding the shaft and a deformable section;
• (b) moving the outer tube relative to the shaft in a distal direction to transition the deformable section of a reamer assembly from an elongated condition to a radially expanded condition;
• (c) after the moving step, retracting the reamer assembly to mechanically extract the bone and/or cellular material from a patient;
• and
• (d) collecting the bone and/or cellular material in a storage container.
