Abstract: A syringe system and components thereof are disclosed. The system may include a syringe body having a hollow lumen, a proximal open end, and a distal end. The syringe body may be configured to house a fluid therein. The syringe system may further include a plunger positioned in the hollow lumen of the syringe body, forming a seal with an inner wall of the syringe body. The plunger may include a removable piston having a shaft extending from the distal end towards the proximal open end, a stopper removably connected to a distal portion of the shaft, and at least one coupler attached to the distal portion of the shaft. The stopper may be configured to slidably move within the hollow lumen to facilitate movement of the fluid within the syringe body. The coupler may be configured to facilitate removal and attachment of the stopper from the piston.

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.

Abstract: A bellows assembly for a fluid delivery system is a multi-component device that includes a cylindrical pressure jacket and a bellows syringe that is received within the pressure jacket. The bellows syringe includes a cap member and a bellows member. The bellows syringe in one embodiment is adapted to be secured to the pressure jacket by the cap member. The cap member is formed with a discharge port, which may be formed as conventional luer fitting. The discharge port is disposed coaxially within an annular wall on the outward facing side of the cap member and may be recessed within the annular wall. The bellows member is a hollow body that includes a series of bellows sections or rings. A distal end of the bellow member is formed with a discharge neck terminating in a discharge port, and the proximal end is formed with a closed end wall.
