SYDNEY, AUSTRALIA and EDEN PRAIRIE, MN--(Marketwire -06/07/12)- Sunshine Heart, Inc. (SSH) (SHC.AX), a global medical device company focused on innovative technologies for moderate to severe heart failure, today announced that the company has been granted approval by Health Canada to use its next generation C-Pulse® Heart Assist System driver in ongoing clinical studies at Royal Victoria Hospital. The new C-Pulse driver is designed to provide heart failure patients with enhanced patient comfort and performance. The C-Pulse System is a new investigational therapeutic approach based on proven balloon counter-pulsation technology for the treatment of patients with Class III and ambulatory Class IV heart failure.
The C-Pulse driver now comes as a single unit that is half the size, lighter and quieter than the first generation technology. The driver also features a number of software enhancements. The C-Pulse System is currently in an investigational study at Royal Victoria Hospital. The prospective study is designed to evaluate the safety and performance of the C-Pulse System as a treatment for patients with moderate to severe heart failure. To date, four patients have been implanted with the initial C-Pulse System. The company has received Health Canada approval to expand the number of participants in the trial to 20 patients. All trial participants will receive the new C-Pulse driver, which will be used in ongoing and future clinical studies.
"We are pleased to have received Health Canada approval of our next generation C-Pulse driver technology for clinical use," said Dave Rosa, CEO of Sunshine Heart. "We enhanced the driver based on results from our feasibility trial and feedback from physicians and patients. With the reduced size, weight and noise reduction, we expect improvements in patient quality of life due to enhanced comfort and performance. We look forward to making this new technology available to patients enrolled in our clinical studies in Canada in the coming weeks, as well the United States and Europe thereafter."
The external C-Pulse driver inflates and deflates the balloon which is secured by a cuff around the outside of the ascending aorta, the main blood vessel of the heart. The cuff and heart signal sensing wires are attached to the external C-Pulse driver, which inflates and deflates the balloon in sequence with the electrocardiogram (ECG) signal to assist heart function and the pumping capacity of the heart. The balloon deflects the aorta in a "thumb-printing" manner, which is intended to minimize aortic wall strain and maximize blood volume displacement per beat.
About Class III Heart Failure
Heart failure is a common condition in which the heart becomes unable to pump sufficient blood to meet the body's needs. More than five million people in the United States have heart failure, resulting in more than 300,000 deaths each year(1). Heart failure is a progressive condition and typically results from damage to the heart muscle arising from a heart attack or virus.
Cardiologists use the New York Heart Association (NYHA) classification system to define the four classes of heart failure; each class is determined by rating a patient's symptoms to everyday activities and quality of life. More than 1.5 million U.S. heart failure patients are in the Class III or moderate heart failure category which is defined by the limitation of physical activity(2). These patients are comfortable at rest, but levels of activity regarded as less than ordinary cause fatigue, palpitation and/or shortness of breath. The most common treatments for Class III heart failure are drugs, lifestyle adjustments, family education, device therapy (i.e. heart failure pacemaker with or without a defibrillator) or surgery. These standard treatments often do not resolve the progression of heart failure leaving patients without any additional options, hence the need for new treatments for patients living with the disease.

Preliminary Data from european trial, delivered at the 34th Annual International Society for Heart and Lung Transplant April 10th, 2014
Surgical implantation was successful in all patients and does not require cardiopulmonary bypass. Follow-up ranges from 5 days - 6 months with a cumulative follow-up of 493 days. No stroke, myocardial infarction, major bleeding or major infection has occurred due to the device
. One patient developed tachycardia with worsening heart failure 12 hours after surgery without stabilization under medication and underwent left ventricular assist device implantation after 5 days.
4 patients improved clinically under the C-Pulse system with three patients improving their functional status by one NYHA class. So far LVEF has increased by an average of 10-15% in the 3 patients with the longest follow-up. One patient is post-op day 7 and has not yet been assessed for efficacy. Conclusion: The C-Pulse system seems to be a promising therapeutic option and may improve cardiac function over time.
