Abstract:
1. A device for the delivery to a situs of multi-component, highly viscous, polymerizable, composite materials comprising: a barrel having a first and second chamber for holding the components, the chambers being aligned along a longitudinal axis of the barrel, and at least one tongue; a plunger comprising first and second distal legs adapted for slidable entry into the chambers of the barrel and having a proximal end of the plunger comprising external threads; and a plunger actuation member having at least one groove aligned with the at least one tongue for attaching the barrel to the plunger actuation member, a handle permitting rotation of the plunger actuation member with torque sufficient to express the components, and internal threads for cooperation with the external threads of the plunger such that rotation of the plunger actuation member advances the plunger legs into the barrel chambers, such cooperation between the internal threads of the plunger actuation member and the external threads of the plunger allowing the device to withstand pressures up to about 500 to 2,000 psi, the plunger being completely surrounded by the plunger actuation member.
