Abstract
The syringe system has a two separate pathways for delivering two materials for mixing. The syringe system has a plunger unit with two plungers that engage two barrels of a dual barrel cartridge to push the two materials into two separate lumens in a nipple on the dual barrel cartridge. The nipple has side portals for directing the materials away from each other as the materials are pushed out of the side portals. The nipple is inserted into a delivery chamber of a delivery tip that houses a static mixing element. The sidewalls of the delivery chamber mate with surfaces of the nipple such that the materials continue to have separate pathways after being pushed out of the side portals and reach the static mixing element.
