Abstract: A selector valve for a medical fluid delivery device is disclosed. The valve includes a valve bore in fluid communication with an outlet channel, first and second outlet ports, and a selector valve body which includes a valve stem located within the valve bore and having a flow passage. The selector valve body is adapted to place the flow passage in fluid communication with one of the first outlet port, the second outlet port, and a shut-off position.

Abstract: A fluid path set for use with an injection device has a single-patient disposable set and a patency check device. A proximal end of the single-patient disposable set is configured for connecting with the injection device. The patency check device has a proximal end configured for connecting with a distal end of the single-patient disposable set and a distal end configured for connecting with a patient fluid delivery device. The patency check device has a body extending between the proximal end and the distal end. The body has a reversibly expandable interior chamber configured for drawing fluid through the patient fluid delivery device during a patency check. The patency check device further has a locking mechanism configured for controlling the volume of the interior chamber during an injection procedure.

Abstract: A system and method of assembling a disposable fluid pump device is provided. The fluid pump device includes a pump body having a plurality of pump cylinders and at least one inlet selector valve for controlling fluid input to the pump cylinders. The method includes the steps of identifying at least one initial inlet selector valve position; generating, with at least one processor, encoded data representing at least the at least one inlet selector valve position; and setting the at least one selector valve to the at least one initial inlet selector valve position.

Abstract: A fluid pump device is operable by a drive and actuating system. The fluid pump device includes a pump manifold, a plurality of pump cylinders, a plunger reciprocally operable in each of the pump cylinders, and at least one inlet selector valve. The pump cylinders may extend proximally from the pump manifold and are in selective fluid communication with the pump manifold via, for example, respective inlet and outlet check valves. The plungers are reciprocally operable within the pump cylinders and are independently and reciprocally operable by respective piston linear actuators provided in the drive and actuating system. The inlet selector valve is used to establish selective fluid communication between one or more fluid source containers and the pump manifold to control fluid flow into the pump manifold. The inlet selector valve may be located laterally outboard of the pump cylinders and extend generally parallel to the pump cylinders.

Abstract: A bladder syringe for a fluid delivery system includes a cylindrical body, a cap-bladder assembly, a plunger element disposed in the cylindrical body, and a mounting assembly to secure the cap-bladder assembly to the cylindrical body. The cylindrical body has a distal end and a proximal end and defines a throughbore. The cap-bladder assembly is adapted for connection to the distal end of the cylindrical body, and includes a cap body and a bladder. The cap body defines an interior cavity and a distal discharge conduit and is adapted to engage the distal end of the cylindrical body. A disc-shaped bladder is disposed within the interior cavity and typically includes a central membrane portion. The plunger element is disposed in the throughbore of the cylindrical body and is vented to enable evacuation of the space between the plunger element and the cap-bladder assembly in the cylindrical body.
