    摘要: A blood flow calibration system 500 including a computer 400 operable to determine and store calibration data for a flow meter 124, a test system 530 operable to simulate blood flow for the flow meter 124, thereby allowing the computer 400 to determine the calibration data, and a programmer 300 operable to transfer the calibration data from the computer 400 to the flow meter 124. The flow meter 124 preferably includes a power management circuit 348a,b operable to detect whether the flow meter 124 is powered. In the event that the flow meter 124 is unpowered, the power management circuit 348a,b is preferably able to supply power to a portion of the flow meter 124 in order to transfer the calibration data thereto.

    摘要: A physiologic control system and method for controlling a blood pump system such as a VAD system. The pump system includes, for example, a blood pump (12) and a controller (80) for controlling the pump. The system may further include a flow measurement device (124). Various control schemes are disclosed, including according controlling the pump to achieve one or more of a desired speed, flow rate, or flow pulsatility. Additionally, various methods for determining maximal flow (the maximum flow that can be achieved for the patient while maintaining certain parameters or within certain boundaries) are disclosed.

    摘要: A physiologic control method and system for an implantable blood pump includes operating the pump at a predetermined speed and monitoring the patient's diastolic pump flow rate. The predetermined speed is varied in response to the diastolic pump flow rate. The pump speed may further be adjusted in response to the patient's heart rate. The speed may be increased and decreased in response to corresponding changes in the diastolic pump flow rate, and increased in response to an increase in heart rate.

    摘要: A self-contained peristaltic pump includes a flexible flow conduit with a plurality of circumferential and/or longitudinal shapechange elements distributed longitudinally and/or transversely along the longitudinal axis of the flow conduit. The activations of the shapechange elements result in the positive displacement of fluid in the anterograde direction (i.e. from the anterior end of the pump to the posterior end).
