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: 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: Devices and methods for enhancing the operations of fluid systems are provided. For example, this document provides pressure differential relief valves that are well suited for use with medical fluid reservoirs. The pressure differential relief valves provided herein are described in the context of a medical fluid system, such as an extracorporeal blood flow circuit, but the devices and methods provided herein can be implemented in other types of fluid systems including, but not limited to, pneumatic systems, hydraulic systems, fluid power systems, petroleum systems, and various other types of gaseous or liquid-based fluid systems.
