Expandable Corpectomy Cage for Cervical Spine Reconstruction

Description:

Project ID: D2009-32

Invention novelty:

Open design, variable height corpectomy cage may be secured and released once implanted, and features expandable mesh material into which bone graft material may be packed.

 

Value proposition:

·       Four variable length telescoping titanium rods may be straight or curved to fit the area of the spine that is being repaired.

·       Ratcheting mechanism allows the telescoping rods to be varied in length in finite increments.

·       May be secured by serrations and released once implanted

·       Set screws are provided to lock the telescoping rod in the desired position once the appropriate spacing has been achieved between the adjacent vertebrae

·       Expandable titanium mesh material forms a tubular cage into which bone or bone graft material is packed

·       After bone graft material is packed into the cage, a fourth lateral mesh wall is attached to the open side of the cage to form a completely contained cage structure.

·       End rings may be ovoid, trapezoid or other generally four sided shapes may be utilized to efficiently match the removed vertebrae.

Applications:

Corpectomy cage provides support in place of removed or damaged vertebrae.
