A left ventricular assist device (LVAD) is a pump that we use for patients who have reached end-stage heart failure. We surgically implant the LVAD, a battery-operated, mechanical pump, which then helps the left ventricle (main pumping chamber of the …

2022年12月14日 · Durable implantable left ventricular assist devices (LVADs) have been shown to improve survival and quality of life for patients with stage D heart failure. Even though LVADs remain underused overall, the number of patients with heart failure supported with LVADs is steadily increasing.

2023年8月8日 · Circulatory support with the use of a left ventricular assist device (LVAD) is an emerging field. The landmark REMATCH trial that compared LVADs with optimal medical therapy in class IV HF patients found a 48% reduction in mortality from any cause [4].

The HeartMate 3™ LVAD, a mechanical circulatory support pump with Full MagLev™ Flow Technology has significantly advanced the field of LVAD therapy, setting the standard with innovation and outstanding clinical outcomes that make a …

This paper focuses on the design of magnetic bearing and drive motor for a novel third-generation LVAD. In the proposed novel LVAD configuration, a centrifugal pump is levitated by an active magnetic bearing in the radial plane and by a passive magnetic bearing in the axial direction.

2025年3月18日 · This study aims to design a small-sized embedded axial flux permanent magnet synchronous motor (AFPMSM) for a left ventricular assist device (LVAD) pump. The power density per unit volume of the AFPMSM structure is much higher than conventional radial flux permanent magnet machines, so it is preferred for the geometry of the pump structure. For further enhancement in torque density and ...

A left ventricular assist device (LVAD) is a small, surgically implanted mechanical pump that supports a weakened heart's left ventricle. When the left pumping chamber of the heart thickens — known as left ventricular hypertrophy — it may not be able to pump efficiently. LVADs help ensure the heart pumps enough blood to meet the body's needs.

Since the left ventricle accounts for 80% of all heart failures, implantable left ventricular assist devices (LVAD) are seen as a promising alternative to many heart transplants. Diaphragm-type LVADs are already routinely used as “bridge to transplant” devices at more than 160 clinical centers around the world.

Ambulatory patients with a left ventricular assist device (LVAD) are increasing in number, and so is their life expectancy. Thus, there is an increasing need for care of these patients by non-LVAD specialists, such as providers in the emergency ...

A left ventricular assist device (LVAD) is a pump for patients with advanced heart failure. Once implanted, the LVAD is designed to help the left ventricle of your patient’s heart pump blood to the rest of their body.
