News & Events

Eden Prairie, MN: May 9, 2013: Sunshine Heart, Inc. (NASDAQ: SSH) announced today the implant of the first patient in the OPTIONS HF C-Pulse System Multicenter Study. The post market study is intended to treat patients with moderate to severe heart failure.

The patient was implanted on May 7, 2013 at the German Heart Institute - Berlin (DHZB), a leading international hospital dedicated to the treatment of cardiovascular and thoracic diseases. In particular, DHZB is focused on implantation of mechanical circulatory support systems and for heart and lung transplantation. The procedure was completed by Professor Roland Hetzer, Chairman of the Department of Cardiothoracic and Vascular Surgery in cooperation with Dr. Holger Hotz of Cardio Centrum Berlin. The implant utilized Sunshine Heart’s enhanced cuff, which is pre-sutured and pre-marked providing ease of use for implanting surgeons.

“We are extremely pleased to announce the implant of the first patient at the German Heart Institute - Berlin in our European multicenter post market study,” said Dave Rosa, Sunshine Heart’s Chief Executive Officer. “In particular, we are encouraged to see early success of our next generation cuff in its ability to improve the ease of implant and allow for better predictability of proper securement. We anticipate the activation of additional sites in the coming months and look forward to updating the market with our progress as enrollment proceeds.”

 The World Heart Failure Society estimates that heart failure affects over 16 million Europeans of all ages and is responsible for more hospitalizations than all forms of cancer combined.

The OPTIONS HF study is structured to enroll a total of 50 patients with moderate to severe heart failure at ten European centers. This study is designed to provide additional clinical data to assist in publications and reimbursement. The data being collected is similar to that which is being collected in the U.S. pivotal trial.

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 counterpulsation 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. Combined, these potential benefits may help sustain the patient’s current condition or, in some cases, reverse the heart failure process, thereby potentially preventing the need for later-stage heart failure devices, such as left ventricular assist devices (LVADs), artificial hearts or transplants. It may also provide relief from the symptoms of Class III and ambulatory Class IV heart failure and improve quality of life and cardiac function. Based on the results from our feasibility trial, we also believe that some patients treated with our C-Pulse System will be able to stop using the device due to sustained improvement in their conditions as a result of the therapy.

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