Abstract: In a bone cement mixing and delivery device, a plug can be removably disposable in an injection passage of a cylindrical container. A mixing screw can rotate in a chamber of the container and has a screw thread extending along an outer surface of the mixing screw as well as a return passage extending through the mixing screw from the proximal end to the distal end thereof. In a mixing mode of the device, a mixing rod engages and rotates the mixing screw about a longitudinal axis of the cylindrical container causing material disposed in the chamber to be moved distally and return to the proximal end of the chamber through the return passage of the mixing screw. In an injection mode of the device, the plug can be removed from the injection passage and an injection rod occludes the return passage of the mixing screw.

Abstract: An apparatus for mixing bone cement can comprise a receiving chamber, a mixing chamber, a cannula, a base, and a piston located within the mixing chamber. The receiving chamber defining a conduit. The mixing chamber in fluid communication with the receiving chamber. The mixing chamber configured to house a first component of the bone cement. The cannula located in the receiving chamber and in fluid communication with the conduit. The base including a bladder arranged to be punctured by the cannula, the bladder configured to house a second component of the bone cement. Upon puncturing of the bladder by the cannula the second component of the bone cement passes through the conduit and the cannula into the mixing chamber. The piston configured to seal the mixing chamber upon movement of the piston from a first position relative to the conduit to a second position relative to the conduit.

Abstract: Implementations described herein include a hone cement mixing and delivery device including a cylindrical container defines a chamber and has an injection passage disposed at the distal end thereof. A plug can be removably disposable in the injection passage. The mixing screw is rotatably disposable in the chamber and has a screw thread extending along an outer surface of the mixing screw as well as a return passage extending through the mixing screw from the proximal end to the distal end thereof. In a mixing mode of the device, a mixing rod engages and rotates the mixing screw about the longitudinal axis of the cylindrical container causing material disposed in the chamber to be moved distally and return to the proximal end of the chamber through the return passage of the mixing screw. In an injection mode of the device, the plug can be removed from the injection passage and an injection rod occludes the return passage of the mixing screw. The injection rod engages and rotates the mixing screw about the longitudinal axis moving material disposed in the chamber through the injection passage.
