  • Patent number: 10561771
    Abstract: An implantable heart assist system includes a compressible pumping chamber including an inlet conduit to be placed in fluid connection with the descending thoracic aorta and an outlet conduit to be placed in fluid connection with the thoracic aorta; and a pump system comprising a first rigid member, a second rigid member positioned so that at least a portion of the pumping chamber may be positioned between the first and second rigid members, a drive system configured to cause the second rigid member to move toward or away from the first rigid member, and a controller in operative connection with the drive system and controlling the drive system, wherein movement of the second rigid member toward the first rigid member results in compresses the pumping chamber and movement of the second rigid member away from the first rigid member expands the pumping chamber.

  • Publication number: 20030144573
    Abstract: A back flow limiting valve member which substantially, but not entirely, blocks reverse blood flow through a blood pump, such as when the blood pump is not pumping blood or pumping below a predetermined rate. The valve member can operate passively or actively in order to provide a limited back-flow through the blood pump to prevent clot formation. The back flow check valve may also be employed to restrict reverse blood flow through a blood flow conduit or blood vessel rather than in a blood pump.

  • Patent number: 5558617
    Abstract: 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.

  • Patent number: 5098369
    Abstract: 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.

  • Patent number: 5078134
    Abstract: A patient-worn harness or vest protects at-risk patients from the possibly fatal results of heart arrhythmias. The harness or vest incorporates sensing electrodes for monitoring heart condition, a microprocessor and memory for processing signals received from the sending electrodes and comparing same with patient's data, and skin-contacting pulsing electrodes for applying electrical pulses to the patient's chest wall responsive to signals received from the microprocessor. The electrodes include automatic tightening and electrolyte gel release mechanisms for reducing impedance at the electrode-skin interface. A servicing subsystem is provided for the harness or vest and may be used to interface with the harness or vest and may be used to interface with the harness or vest and also to communicate with remote health care personnel through a suitable telephone link.
