Abstract
An apparatus and method for mixing two components and delivering the mixture to a patient. The apparatus contains a mixing chamber for mixing a liquid component and a powder component. The liquid component and powder component are mixed within the mixing chamber by rotation of a collapsible mixing element. A high strength cartridge capable of withstanding high opposing axial loads from the mixing chamber and a threaded rod generates force to drive the curable material from the mixing chamber. A plunger connected to the rod is then advanced through the mixing chamber to force the mixture out of the mixing chamber and deliver the mixture to the patient.
