Assisted circulation for end-stage chronic heart failure
Despite the trend in the use of electromechanical left ventricular assist devices (LVAD), the highly compact, long lasting, and endurance characteristics of the new pneumatic system has its place in the treatment of end-stage chronic heart failure. The ProCor Model 1 LVAD has an implantable pump whi...
