摘要： A ventricular assist device (VAD) having static seal structure for a pump housing which includes a support structure, a first sealing element, and a second sealing element. The support structure circumscribes a pump chamber and includes a first sealing surface, an opposing second sealing surface, and a fluid transfer end interposed between the sealing surfaces. The support structure provides a fluid flow path running through the fluid transfer end and into the pump chamber via an inlet bore and from the pump chamber back through the fluid transfer end via an outlet bore. The first sealing element is disposed on the first sealing surface, and the second sealing element is disposed on the second sealing surface. The sealing elements are configured for forming sealing interfaces in the pump housing, establishing a static seal that isolates the pump chamber from an environment external to the fluid pump housing.
