Sunshine Heart, Inc., is an early-stage medical device company focused on developing, manufacturing and commercializing its C-Pulse Heart Assist System for treatment of Class III and ambulatory Class IV heart failure. The C-Pulse Heart Assist System utilizes the scientific principles of intra-aortic balloon counter-pulsation applied in an extra-aortic approach to assist the left ventricle by reducing the workload required to pump blood throughout the body, while increasing blood flow to the coronary arteries. As of December 31, 2011, the Company was in the process of obtaining regulatory approvals necessary to sell its product. During the year ended December 31, 2011, the Company completed enrollment and implantation of 20 patients in the North American feasibility phase of its trial. In April 2011, the Food and Drug Administration (FDA) approved an expansion protocol to allow the Company to implant up to 20 additional patients and add two additional centers to its feasibility study.
