Bone Marrow Aspiration System with IMBIBE Syringe and IMBIBE Disposable Delivery Instrumentation, used with VITOSS Bone Graft Substitute
The disposable IMBIBE devices provide spine and orthopedic surgeons with a simple method for harvesting a patients own bone marrow, mixing it with VITOSS Bone Graft Substitute, and delivering the mixture to the bone graft site. We believe IMBIBE, when used together with VITOSS Bone Graft Substitute, will provide greater flexibility and options for surgeons. IMBIBE is covered by a U.S. issued patent.
