Abstract: Various syringe systems are disclosed. One illustrative syringe system may include a syringe body having a hollow lumen and a distal end. The syringe body may be configured to house a plurality of fluids therein. A first plunger may be positioned in the hollow lumen of the syringe body, forming a first seal with an inner wall of the syringe body, and forming a first compartment between the first plunger and the distal end of the syringe. A second plunger may be positioned proximal to the first plunger in the hollow lumen of the syringe body, forming a second seal with the inner wall of the syringe body, and forming a second compartment between the first plunger and the second plunger. A plurality of recesses may be disposed about the inner wall of the syringe body near the distal end of the syringe body.
