Patent ID: 8308731

Claim:
A device for mixing and dispensing a bone cement mixture, the device comprising: a first cylindrical housing having a proximal end, a distal end, and a first chamber formed therein for containing a first and a second bone cement component, the distal end including a first outlet in fluid communication with the first chamber, the proximal end configured to receive a first plunger; a second cylindrical housing having a proximal end, a distal end, and a second chamber formed therein for containing a mixing element, the distal end including a second outlet in fluid communication with the second chamber, wherein the proximal end receives a second plunger to advance the mixing element from the second chamber through the second outlet and into the first chamber through the first outlet, wherein the second plunger rotates the mixing element to mix the first and second bone cement components together within the first chamber to form the bone cement mixture, and wherein the first plunger actuates within the first chamber to dispense the bone cement mixture from the first chamber through the first outlet after withdrawal of the mixing element therefrom, wherein the mixing element includes a first configuration and a second configuration, wherein the mixing element is in the first configuration when the mixing element is advanced from the second chamber into the first chamber, wherein the mixing element is in the second configuration when the mixing element mixes the bone cement mixture within the first chamber.
