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.

摘要： An apparatus and a method for connecting medical tubing or any other type of fluidic circuit conduits (e.g., cannulae) to a ventricular assist device (“VAD”) or any other pumping device used for blood pumping during cardiac circulatory support for vascular surgery. The apparatus and the method prevent air bubbles from entering a cardiac circulatory support system when connecting cannulae to a VAD that may later enter the blood stream of a patient during cardiac surgery, and also provide for purging any air bubbles that may have entered the cardiac circulatory support system during a cannulae-VAD connection.

摘要： Embodiments include Ventricular Assist Devices (VADs) with clips that help hold a cannula to the VAD. In some embodiments the clip embraces a cannula that has been placed around a cannula connector. In further embodiments an additional clip connects the first clip to the VAD housing preventing the first clip from slipping. The clip and additional clip may form a single piece. Further embodiments include a blood pumping sac located inside a cavity in the VAD forming one or more air chambers between the sac and the cavity walls, and an airflow channel leading from the air chambers to an airflow port allowing the sac to be evenly pressurized and depressurized. Still further embodiments include one or more purge devices that assist in removing bubbles from the VAD and helping connect cannulas to the VAD. Additional embodiments include a torqueable wrench to facilitate use and proper sealing of the device.
