An apparatus for mixing and dispensing a multi-component compound. The device includes a tubular body with an internal chamber for mixing the multi-component compound. Disposed within and extending beyond the tubular body is a rod having a mixing disc located near a distal end. Also disposed within the tubular body is a moveable piston with a central opening through which the rod may pass.

What is claimed: 1. An apparatus for mixing and dispensing a multi-component compound to a cannula, comprising: a tubular body defining an internal chamber for mixing the multi-component compound therein, the tubular body having a distal end comprising an opening in communication with the internal chamber; a rod disposed within the tubular body, said rod having a proximal end extending out of the tubular body and a distal end extending into the tubular body; a moveable piston separate from and contained within the tubular body; a sensor for sensing a characteristic of the compound within the apparatus; an output valve having an inlet in fluid communication with said opening in said distal end of the tubular body, said output valve having a first outlet in fluid communication with a patient delivery lumen and a second outlet in fluid communication with a shunt lumen, said output valve configured to direct flow from the opening into either the patient delivery lumen or the shunt lumen, said output valve operably coupled to said sensor; a selectable locking mechanism carried by said rod, said locking mechanism having a first selectable configuration in which said locking mechanism allows said rod to move substantially freely relative to said piston and a second selectable configuration which couples said rod to said piston such that distal movement of said rod causes said piston to move distally through said tubular body. 2. The apparatus of claim 1, further comprising bone cement contained within said tubular body. 3. The apparatus of claim 1, further comprising a mixing disc near the distal end of the rod. 4. The apparatus of claim 3, wherein the removable cover is configured such that the moveable piston may be attached to the removable cover. 5. The apparatus of claim 3, further comprising a mechanism to attach the moveable piston to the mixing disc at the distal end of the rod. 6. The apparatus of claim 1, further comprising a mixing paddle near the distal end of the rod. 7. The apparatus of claim 1, wherein the proximal end of the tubular body is configured with a removable cover. 8. The apparatus of claim 1, wherein the moveable piston has a central opening through which the rod extends.
