摘要： An inflow conduit of a ventricular assist device configured to prevent formation of recirculation and stagnation zones as well as collapse due to external forces or pump induced suction can be rigid and have a funnel like shape with an elbow to accommodate a patient anatomy. Stiffening elements and pressure sensing devices can also be provided associated with the inflow conduit.

摘要： A blood pump apparatus can include a pump housing having a drive chamber containing a drive mechanism. A cupped member can be connected to the housing and the drive mechanism can include a motor for rotating an eccentric shaft. A pumping arm can be provided having one end riding on the eccentric shaft, an intermediate portion pivotably attached to the housing and another end connected to a movable plate. A roller bearing can be mounted on the eccentric shaft on which the arm can ride. A compressible blood chamber having an inlet and an outlet connected can be provided sandwiched between the cupped portion and the movable plate. The motor thus rotates the cam causing the pumping arm to pivot which cycles the movable plate against the blood chamber to pump blood. The movable plate can be implanted adjacent a lung such that the lung moves with the plate as blood is pumped and thereby functions as a compliance chamber. A speed reducer can be provided between the motor and the eccentric shaft. A hermetically sealing bellows can be provided to seal the drive chamber and the end of the pumping arm from body fluids. An enclosure bag can be provided surrounding all or a portion of the blood pump to provide a tissue friendly surface and to prevent tissue from becoming caught in the moving parts of the blood pump. A position sensor can be included for determining a volume of blood in the chamber for use by an electronic controller to control the speed of the motor to optimize pumping action.

摘要翻译：血泵装置可以包括具有包含驱动机构的驱动室的泵壳体。杯形构件可以连接到壳体，并且驱动机构可以包括用于旋转偏心轴的马达。可以设置一个泵臂，其一端位于偏心轴上，中间部分可枢转地附接到壳体，另一端连接到可移动板。滚子轴承可以安装在手臂可以骑行的偏心轴上。具有入口和出口连接的可压缩血液室可以被夹在杯状部分和活动板之间。因此，电动机使凸轮旋转，使得泵臂枢转，循环可移动板抵靠血液室以泵送血液。可移动板可以在肺附近植入，使得当血液被泵送时肺随着板移动，从而起到顺应性室的作用。电动机与偏心轴之间可设有减速器。可以提供气密密封的波纹管以将驱动室和泵臂的端部与体液密封。可以围绕血液泵的全部或一部分设置封闭袋，以提供组织友好的表面并防止组织被卡在血液泵的运动部分中。可以包括位置传感器，用于确定腔室中的血液体积，供电子控制器使用，以控制电机的速度以优化泵送动作。
