Abstract:
A dispensing system for dispensing first and second materials to a desired location within the mouth of a patient, the dispensing system comprising:means for separately delivering first and second materials;a hollow delivery tip configured to direct material received within the tip to a specific desired location within a patient's mouth; andmeans for flexibly coupling the delivery tip in fluid communication with the delivering means such that the first and second materials are selectively delivered through the coupling means from the delivering means to the delivery tip while the delivering means is remotely held relative to the hollow delivery tip, wherein the coupling means has means for dividing the coupling means into first and second separate lumens along its length such that the first and second materials delivered from the delivering means are retained in the separate lumens until reaching the hollow delivery tip, thereby preventing the first and second materials from mixing with each other until reaching the delivery tip.
