Patent ID: 7445633

Claim:
A method for impregnating a porous bone replacement block, comprising: a) enclosing a porous bone replacement block in a chamber with two openings that can be closed, b) introducing a liquid impregnating agent into the chamber until the porous bone replacement block is at least partly immersed in the liquid impregnating agent, c) closing one of the two openings of the chamber, d) evacuating the chamber at least partly through the other opened opening so that the air contained in the pores of the porous bone replacement block is at least partly removed from it, and e) terminating the vacuum produced in the chamber by supplying air or a gas through one of the two openings of the chamber so that the vacuum produced in the pores of the porous bone replacement block is terminated by the impregnating agent penetrating into the pores of the porous bone replacement block immersed into the liquid impregnating agent; wherein enclosing the porous bone replacement block in the chamber includes enclosing the porous bone replacement block in a cylindrical container with a hollow space, an internal thread provided in the hollow space and a matching lid with external thread, and varying a capacity V by screwing the matching lid into the cylindrical container to a greater or lesser depth.
