Patent ID: 8632242

Claim:
A system for impregnating a porous bone replacement material, the system comprising: a syringe, the syringe defining a hollow syringe chamber and including a piston movable within the hollow syringe chamber so as to form an airtight seal in the hollow syringe chamber, the syringe defining a first attachment end; an impregnation chamber having an internal volume that can varied, the impregnation chamber defining a hollow space that receives the bone replacement material and an impregnating agent, the impregnation chamber defining at least one opening, wherein the first attachment end of the syringe is configured to attach to the impregnation chamber so as to place the hollow syringe chamber in fluid communication with the impregnation chamber via the first opening, and to form an airtight seal between the syringe and the impregnation chamber, and wherein withdrawing the piston in the hollow syringe chamber produces a negative pressure in the hollow space that causes air disposed in the pores to exit the pores, and further causes the impregnating agent to enter the pores.
