Abstract: Extracorporeal circuit devices can be used for on-pump open-heart surgery to support surgical procedures such as coronary artery bypass grafting. In some cases, a centrifugal pump is used as part of an extracorporeal circuit. Centrifugal pump heads are described herein that induce flow on two sides of an impeller plate, and that can be conveniently mechanically assembled.

Abstract: Fluid coupling devices for connecting to and disconnecting from a male barbed fitting to provide a continuous flow path or a flow termination point, include a frame and an elastomeric sealing material disposed about and at least partially encapsulating the frame. The frame can have a first end including a connecting element. The frame can also have a second end including a ring that has two inwardly directed, radial locking tabs. At least a portion of the sealing material can define a thru lumen. At least a portion of the thru lumen can include a tapered, inner portion configured to create a sealed connection with a male barbed fitting. The second end of the fluid coupling device, when compressed, can deflect the locking tabs in a radially outward direction for releasing the male barbed fitting.

Abstract: Devices and methods for enhancing the operations of fluid systems are provided. For example, this document provides variable-elevation drop tubes that are well suited for use with medical fluid reservoirs. While the variable-elevation drop tubes provided herein are described in the context of a medical fluid system, such as an extracorporeal blood flow circuit, it should be understood that the devices and methods provided herein are not limited to such contexts.

Abstract: One-way valve devices can be used within fluid systems. For example, this document provides one-way valves that can be installed within a lumen of a tube, a fitting, and other types of tubular members. In some embodiments, the one-way valve includes a unitary frame and a ball member that is loosely constrained within the confines of the frame.
