Heartware International, Inc. is a medical device company. The Company develops and manufactures miniaturized implantable heart pumps or ventricular assist devices for patients suffering from advanced heart failure. The HeartWare Ventricular Assist System (HVAD System), which includes a ventricular assist device (VAD) or blood pump, patient accessories and surgical tools, provides circulatory support for patients in the advanced stage of heart failure. The core of the HVAD System is a continuous flow blood pump, the HVAD pump. The HVAD System is designed to be implanted adjacent to the heart, avoiding abdominal surgery, directly adjacent to the heart. The Company's hybrid system is used for suspending the impeller. The impeller is suspended within the pump housing by the opposing forces of passive magnets and hydrodynamic thrust generated by the pump impeller, which circulates a cushion of blood.
