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 کاملSuccessful management of a left ventricular assist device malfunction in an outpatient setting.
Heart disease kills as many people as nearly all other causes of death combined. Chronic, progressive, end-stage heart failure results in substantial health care costs and immeasurable suffering for both individuals in particular and society in general. Ventricular assist devices are having an increasing role in supporting patients with severe circulatory compromise. These devices provide suppo...
متن کاملImplantable left ventricular assist system.
The first clinical application of the first-generation pulsatile implantable left ventricular assist system (LVAS) was in the mid 1980 s as a bridge to transplantation and contributed to an advancement of this field from a clinical experiment to an established therapeutic option for treating advanced heart failure patients. However, there have been technological limitations that have surfaced a...
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 کاملAn Implantable Intravascular Pressure Sensor for a Ventricular Assist Device
The aim of this study is to investigate the intravascular application of a micro-electro-mechanical system (MEMS) pressure sensor to directly measure the hemodynamic characteristics of a ventricular assist device (VAD). A bioand hemo-compatible packaging strategy is implemented, based on a ceramic thick film process. A commercial sub-millimeter piezoresistive sensor is attached to an alumina su...
