Cardiac Assist Devices
The Surgical Research Laboratory at Sinai Hospital of Detroit has as its primary goal the development of mechanical and biological technics for augmenting or replacing the function of a damaged heart. Scientific contributions from our group include the development of a cardiac pacemaker, a method for electronic control of bladder evacuation, technics for chronic stimulation of nerves, and a met...
متن کاملVentricular assist devices and non-cardiac surgery
The use of ventricular assist devices has expanded significantly since their approval by the Food and Drug Administration in the United States in 1994. In addition to this, the prevalence of heart failure continues to increase. We aim to provide an overview of perioperative considerations and management of these patients for non-cardiac surgery. We performed a Medline search for the words "vent...
متن کاملCardiac Remodeling and Recovery: Lessons from Mechanical Ventricular Assist Devices
Cardiac injury, regardless of etiology, typically leads to an increase in wall stress, decreased compliance, reduced systolic function, and progressive chamber dilation. This process is termed “remodeling” and is associated with a worse prognosis in patients with heart failure. Several drugs have been shown to have an effect on inducing reverse remodeling or reducing ventricular dilatation, inc...
متن کاملOptimization of Cardiac-Cycle Synchronized Control for Ventricular Assist Devices
Heart failure is one of the leading causes of death in the developed countries. The use of ventricular assist devices (VADs) is an option for treating patients with end-stage heart failure which is increasingly applied, while heart transplantation represents the gold standard therapy. The reason for the increased use is both due to a shortage of donor organs and the improvement of VAD technolog...
متن کاملLow Permeability Biomedical Polyurethane Nanocomposites for Cardiac Assist Devices
Introduction Biomedical polyurethanes generally possess good biocompatibility and mechanical properties but, due to the low Tg and relatively high concentration of soft segments, are relatively permeable to air and water vapor. The ‘traditional’ approach to the permeability problem is to modify the chemistry of the copolymer, particularly that of the soft segment. For example, replacement of po...
