EDEN PRAIRIE, MN and SYDNEY, AUSTRALIA--(Marketwire - Aug 30, 2012) -  Sunshine Heart, Inc. (NASDAQ: SSH) (ASX: SHC) announced today that it has filed its submission for an Investigational Device Exemption (IDE) with the U.S. Food and Drug Administration (FDA).

The Company's IDE submission relates to the proposed use of the C-Pulse Heart Assist System for patients suffering with moderate to severe heart failure. If successful, the Company believes this trial should provide the data required by the FDA to permit approval, which would allow the Company to commercialize the C-Pulse System in the U.S. This pivotal trial follows the FDA's review of the six month safety and efficacy data reported from the 20-patient North America feasibility study. In March, 2012, the FDA completed its review of the C-Pulse System feasibility trial data and concluded that applicable requirements had been met for the Company to move forward with an IDE application for its pivotal trial. Dr. Bill Abraham of Ohio State University Medical Center will be the national principal investigator for this proposed 388 patient pivotal trial. The proposed primary endpoint is reduction of events such as re-hospitalization due to worsening heart failure and heart failure-related mortality. The study will evaluate results for patients that receive the C-Pulse System in comparison to a control group that is managed on optimal medical therapy.

About the C-Pulse® Heart Assist System
The C-Pulse Heart Assist System, or C-Pulse System, an investigational device in the United States, Canada and countries that do not recognize the CE mark approval, 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. Operating outside the patient's bloodstream, the extra-aortic approach of the C-Pulse technology offers greater flexibility, allowing patients to safely disconnect to have intervals of freedom to perform certain activities such as showering. The C-Pulse System may help maintain the patient's current condition and, in some cases, reverse the heart failure process, thereby potentially preventing the need for later stage heart failure therapies, such as left ventricular assist devices (LVADs), artificial hearts or transplants.

Caution: Investigational device, limited by Federal (or United States) Law to Investigational use.
