In December 2013, HeartWare® International announced acquisition of CircuLite®, Inc. CircuLite, Inc. designs and develops minimally-invasive devices for long term partial circulatory support which are intended to work in conjunction with the heart to enhance clinical outcomes and improve quality of life for patients and their families. SYNERGY is a miniature ventricular support system that is intended to reduce symptoms of heart failure and associated re-hospitalizations, as well as to improve exercise tolerance and quality of life. SYNERGY has received CE Mark approval in Europe. Next-generation circulatory support systems that incorporate CircuLite's micro-pump technology include an endovascular system, a right-heart system and a pediatric system. CircuLite's devices are for patients with chronic heart failure who are not responding to standard medical care, but are not candidates or eligible for heart transplantation
