Design an Equivalent Left Ventricular Assist Device for Medical Equipment Labs
LVAD is a mechanical pump supporting a weak heart function and blood flow. Sometimes, the heart may not recover fast enough to take over the pumping action immediately after surgery, in such patients a temporary support device has been employed to maintain the pumping action until the patient’s own heart recovers. This device can be considered as a temporary alternative before the process of ar...
متن کاملThe vortex of three-dimensional mapping with a centrifugal ventricular assist device.
Introduction Left ventricular assist devices (VADs) are increasingly utilized for mechanical support in medical therapy refractory advanced heart failure. Thirdand fouth-generation VADs have a miniaturized intrapericardial design. The HeartWare HVAD is FDA approved for bridge to transplantation, while the HeartMate 3, which has a similar design, remains investigational in the USA. These centrif...
متن کاملSimultaneous ramp right heart catheterization and echocardiography in a ReliantHeart left ventricular assist device
Many clinicians caring for patients with continuous flow left ventricular assist devices (CF-LVAD) use ramp right heart catheterization (RHC) studies to optimize pump speed and also to troubleshoot CF-LVAD malfunction. An investigational device, the ReliantHeart Heart Assist 5 (Houston, TX), provides the added benefit of an ultrasonic flow probe on the outflow graft that directly measures flow ...
متن کاملImprovement of Left Ventricular Assist Device (LVAD) in Artificial Heart Using Particle Swarm Optimization
In this approach, the Left ventricular assist pump for patients with left ventricular failure isused. The failure of the left ventricle is the most common heart disease during these days. Inthis article, a State feedback controller method is used to optimize the efficiency of a samplingpump current. Particle Swarm Algorithm, which is a set of rules to update the position andvelocity, is applied...
متن کاملPercutaneous Ventricular Assist Devices: New Deus Ex Machina?
The development of ventricular assist devices has broadened the means with which one can treat acute heart failure. Percutaneous ventricular assist devices (pVAD) have risen from recent technological advances. They are smaller, easier, and faster to implant, all important qualities in the setting of acute heart failure. The present paper briefly describes the functioning and assets of the most ...
