摘要

2021 MAY 05 (NewsRx) - By a News Reporter-Staff News Editor at Disease Prevention Daily - According to news reporting originating from Alexandria, Virginia, by NewsRx journalists, a patent by the inventors Medvedev, Alexander (Ann Arbor, Ml); Yanai, Masamichi (Ann Arbor, Ml), filed on September 20, 2019, was published online on May 3, 2021. The assignee for this patent, patent number 10,980,928, is TCI LLC (Pleasanton, California, United States). Reporters obtained the following quote from the background information supplied by the inventors: "The present invention relates in general to ventricular support pumps and controls, and, more specifically, to a ventricular assist device for reducing load applied to a weakened ventricle during the systolic phase. "Many types of circulatory assist devices are available for either short term or long term support for patients having cardiovascular disease. For example, a heart pump system known as a left ventricular assist device (LVAD) can provide long term patient support with an implantable pump associated with an externally-worn pump control unit and batteries. The LVAD improves circulation throughout the body by assisting the left side of the heart in pumping blood. One such system is the DuraHeart.RTM. LVAS system made by Terumo Heart. Inc., of Ann Arbor, Mich. The DuraHeart.RTM. system employs a centrifugal pump with a magnetically levitated impeller to pump blood from the left ventricle to the aorta. The impeller can act as a rotor of an electric motor in which a rotating magnetic field from a multiphase stator couples with the impeller and is rotated at a speed appropriate to obtain the desired blood flow through the pump.
