Linear tubular switched reluctance motor for heart assistance circulatory: Analytical and finite element modeling [PDF]

, 2011
A linear tubular switched reluctance motor is presented. This actuator is devoted to be used as a left ventricular assist device (LVAD). In order to avoid thrombosis, this actuator includes pump and valve functions. By using a St. Jude Medical mechanical

Pressure, Flow Rate and Operating Speed Characteristics of a Continuous Flow Left Ventricular Assist Device During Varying Speed Support

IEEE Access, 2020
Hydraulic performance of Continuous Flow Left Ventricular Assist Devices depends on their pressure head and flow rate relations. Hydraulic characteristics of these devices are expressed by pressure head and flow rate loops in a pulsatile environment as ...

Mechanical Circulatory Support for Right Ventricular Failure

Cardiac Failure Review, 2022
Right ventricular (RV) failure is associated with significant morbidity and mortality, with in-hospital mortality rates estimated as high as 70–75%. RV failure may occur following cardiac surgery in conjunction with left ventricular failure, or may be ...

The cost-effectiveness of left ventricular assist devices in end stage heart failure

, 2008
With a limited supply of donor hearts, individuals with end-stage heart failure have been offered hope through the use of mechanical devices. Left ventricular-assist devices (LVADs) are a technology designed to work in parallel with the heart but have ...

Successful heart transplantation after 4 years of bridging with HeartWare HVAD for left ventricular noncompaction in an 11-year-old boy with prohibitively high pulmonary vascular resistance

Annals of Pediatric Cardiology
End-stage heart failure due to left ventricular noncompaction (LVNC) poses unique challenges for ventricular assist device implantation, like inflow cannula obstruction due to trabeculations. We report a case of an 11-year-old boy with LVNC who underwent
