Patent ID: 8439929

Claim:
A method of preparing a graft material for a bone surface, the method comprising: providing a first syringe having continuous side wall having an inner surface and an outer surface wherein the syringe has a first end and a second end wherein the inner surface defines a chamber; attaching an adapter to the distal end of the syringe wherein the adapter has a throughbore in fluid communication with the chamber; disposing a first selected amount of solid bone graft material within the chamber; inserting a plunger into the chamber to define a selected volume between the distal end of the plunger and the second end of the first syringe; connecting a second syringe containing a selected amount of a liquid biomaterial to the adapter wherein the second syringe is in fluid communication with the adapter and the first syringe; transferring the liquid biomaterial from the second syringe to the first syringe; venting air through the plunger as the biomaterial is transferred to the first syringe; providing a selected amount of time for the liquid biomaterial to form a gel and a gel matrix containing the solid bone graft material; removing the adapter to provide an unobstructed opening; and depressing the plunger to force the gel matrix from the chamber of the first syringe.
