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.
