Abstract
A device for mixing a bone material with a liquid is provided. The device comprises a chamber having a proximal end and a distal end, and the bone material disposed within the chamber, the bone material comprising a DBM pellet of milled and lyophilized demineralized bone fibers; and a plunger having at least a portion slidably disposed within the proximal end of the chamber and configured to dispense the bone material mixed with liquid from the distal end of the chamber, when the plunger is in an extended position.

1-12. (canceled)
A bone material comprising a mixture of a plurality of first bone fibers having a diameter from about 0.5 mm to about 8.0 mm and a plurality of second bone fibers having a diameter from less than about 0.5 mm to about 0.05 mm, wherein the first bone fibers have their diameter larger relative to the diameter of the second bone fibers.
A demineralized bone matrix pellet comprising demineralized bone matrix dried from a demineralized bone matrix slurry, the demineralized bone matrix slurry being formed from a plurality of first bone fibers having a diameter from about 0.6 mm to about 8.0 mm and a plurality of second bone fibers having a diameter from about 0.5 mm to about 0.05 mm, wherein the first bone fibers have their diameter larger relative to the diameter of the second bone fibers, and the ratio of the first bone fibers to the second bone fibers is about 80:20 respectively or about 90:10 respectively.
