Thermal Analysis of the PediaFlow pediatric ventricular assist device.
Accurate modeling of heat dissipation in pediatric intracorporeal devices is crucial in avoiding tissue and blood thermotrauma. Thermal models of new Maglev ventricular assist device (VAD) concepts for the PediaFlow VAD are developed by incorporating empirical heat transfer equations with thermal finite element analysis (FEA). The models assume three main sources of waste heat generation: coppe...
متن کاملMagnetic design for the PediaFlow ventricular assist device.
This article describes a design process for a new pediatric ventricular assist device, the PediaFlow. The pump is embodied in a magnetically levitated turbodynamic design that was developed explicitly based on the requirements for chronic support of infants and small children. The procedure entailed the consideration of multiple pump topologies, from which an axial mixed-flow configuration was ...
متن کاملAdvances in Mechanical Circulatory Support Quality of Life and Left Ventricular Assist Device Support
More than 5 million Americans are living with heart failure, with an additional 500 000 cases diagnosed each year.1 Ongoing improvements in patient management will only increase the number of patients surviving to develop severe refractory heart failure (stage D). Approximately 5% to 10% of all heart failure patients are classified as stage D and defined as patients who continue to have symptom...
متن کاملAdvanced mechanical circulatory support with the HeartMate left ventricular assist device in the year 2000.
This paper describes the HeartMate left ventricular assist device (ThermoCardiosystems Inc, Woburn, MA) technology, which has been successfully introduced into the clinical arena with more than 2,400 implants as of the year 2000. The review summarizes the clinical experience, and identifies the benefits and limitations of the current state-of-the-art technology of the leading implantable circul...
متن کاملThe LionHeart LVD-2000: a completely implanted left ventricular assist device for chronic circulatory support.
Management of patients with end-stage cardiac disease remains a vexing problem. Limitations in medical management and a fixed supply of donor organs for cardiac transplant have a continued impact on this growing population of patients. Mechanical circulatory support has proved very successful as a means of bridging patients to cardiac transplant when all medical options have been exhausted. The...
