Claim Text:
1. A method for rinsing and delivering a bone graft comprising: a. selecting a delivery syringe comprising a proximal plunger, a distal open bore, and a filter assembly comprising a filter and a nozzle, the filter being removably coupled to the syringe adjacent to the distal open bore, and the syringe having a bone graft material and a cryopreservative solution therein; b. determining a bone graft material:fluid ratio; c. depressing the plunger to expel the cryopreservative solution from the delivery syringe, through the filter and out the nozzle, wherein the bone graft material is maintained within the syringe; d. inserting a distal end of the syringe into a receptacle containing a wash solution and drawing the plunger to aspirate a wash solution into the syringe; e. inverting the syringe to mix the wash solution with the bone graft material; f. depressing the plunger to expel the wash solution; g. d. through f. to wash the bone graft material; h. reconstituting the bone graft material, including inserting the distal end of the syringe into a second receptacle containing a reconstitution fluid and drawing the plunger to aspirate the reconstitution fluid to generate the bone graft with the predetermined bone graft material:fluid ratio; and i. removing the filter assembly from the syringe and delivering the bone graft material through the open bore to a surgical site by depressing the plunger.
