摘要： A ventricular assist device for a heart includes a compression band-stay-pad assembly for encircling substantially the heart perimeter and comprising an elongated band member or chain disposed in a sealed protective structure filled with a lubricating medium. The band member may be fixed at one end and wound upon, or unwound from, a rotatable spool by a drive motor through a speed reducer. Force-transmitting support or stay assemblies are disposed in the protective structure between the band member and a resilient pad assembly for encircling the heart and promoting heart tissue ingrowth therein. The force-transmitting stay assemblies are biased circumferentially, and thus radially outward, by compression return springs disposed therebetween. The resilient pad assembly includes a corrugated surface provided with vertical coil springs, which help prevent damage to heart tissue and facilitate return of the pad assembly to an initial condition, embedded defibrillator electrodes and relatively soft portions to prevent damage to coronary arteries. The device may be constructed so that it can be surgically removed, except for a sealing film and an ingrown pad assembly, which remain in situ on the heart. A net structure suspended below the device supports the apical portion of the heart. In certain embodiments, power or motor devices are provided between respective ones of the force-transmitting stay assemblies to contract and expand the device. The circumferential length of the assembly may be adjustable and/or may comprise two band members movable in opposite directions.

摘要： A ventricular assist device may include a cardiac compression assembly which comprises a gel-filled pad of generally concave configuration, mounted on a pressure plate with peripheral portions of the pad extending beyond the periphery of the plate, to preclude damage to the heart by the peripheral edges of the plate. The gel-filled pad may have undulating opposite sides formed by intersecting rows of raised dimples. The pad also includes portions for suturing the pad to a heart ventricle, and at least some of the dimples on the side of the pad facing the heart ventricle are provided with ventricle tissue growth-promoting islands. An electrode, in the form of a grid having intersecting strips which define dimple-receiving openings therebetween, also may be mounted on the venticle side of the pad. As many as eight circumferentially arranged cardiac compression assemblies, having lower ends pivotally mounted on a support member adapted to be located adjacent the apex of a heart ventricle, may be provided. Operating systems for operating the cardiac compression assemblies may include a motor-driven camming mechanism; a mechanism comprising a device for converting electrical energy to hydraulic fluid energy, two sealed fluid systems, a reversible pump, two bellows and a safety solenoid pump-bypass fluid return valve; or a closed loop system comprising a reversible pump in a fluid supply casing, a hydraulic fluid manifold including a plurality of miniature fluid actuators which may be of arcuate construction to conserve space, and a mechanism for collecting fluid leaking from the actuators and returning it to the fluid supply casing.

摘要： A blood pump having rotor and/or stator touch down zones to prevent pump failure or hemolysis which can occur if the rotor comes into contact with the stator due to power failure or mechanical shock. The touch down zones can include forming, or coating, portions of adjacent surfaces of the stator and rotor which can come into contact if a rotor touch down occurs. The materials used to form or coat the touch down zones can have properties which ensure that no consequential damage to the contacting surfaces occurs.
