Abstract: Sealant delivery systems, sealant applicators, and injection needle assemblies are disclosed. A sealant delivery system includes a sealant applicator that has two chambers separate from one another. Each chamber includes an output port on a distal end thereof. The sealant applicator also has a quarter turn connector disposed on a distal end of the sealant applicator adjacent to the output port of each chamber. The quarter turn connector is shaped to releasably interlock with a corresponding quarter turn connector of an injection needle assembly having input ports or a corresponding quarter turn connector of a dual chamber mixing syringe having mixing ports. When the injection needle assembly or the dual chamber mixing syringe is coupled to the sealant applicator via the quarter turn connector, the input ports or the mixing ports are aligned and sealed with the output port of each chamber of the sealant applicator.

Abstract: Syringe assemblies are described herein. A syringe assembly includes an assembly housing, a first syringe, a second syringe, and a connecting gear. The first syringe is disposed within the assembly housing. Each plunger is movable within the respective syringe cavity and defines a respective chamber in the respective syringe cavity, wherein the respective chamber is in fluid communication with the respective syringe port, the respective plunger comprising a respective gear rack extending longitudinally along the respective plunger. The connecting gear is rotatably coupled to the assembly housing. The connecting gear is configured to be in meshed engagement with at least one of the first gear rack and the second gear rack of the syringes.

Abstract: A dual-chamber syringe may include an end wall and a primary plunger. The primary plunger may include a primary stopper. The primary stopper may form a primary chamber with the end wall. A secondary plunger may be in mechanical association with the primary plunger. The secondary plunger may include a secondary stopper. The secondary stopper may form a secondary chamber with the primary stopper. A primary nozzle may extend from the end wall and may be in fluid communication with the primary chamber. A secondary nozzle may extend from the end wall and may be in fluid communication with the secondary chamber.

Abstract: Valves and medication delivery systems including valves are described herein. A valve includes a valve body and a valve element. The valve body defines a first flow path, a second flow path, and a catheter flow path. The valve element is disposed within the valve body, wherein the valve element is configured to permit fluid communication between the first flow path and the second flow path in a priming position, and is configured to permit fluid communication between the first flow path and the catheter flow path in a dispensing position.
