CE Mark For World’s Smallest Surgically Implanted Blood Pump

In short

US/German device company CircuLite®, Inc. has announced that it has received CE Marking approval for the Synergy® Circulatory Support System, claimed by the company to be the world’s smallest surgically implanted blood pump designed for long-term use in patients diagnosed with chronic heart failure. Synergy is described as a micro-pump, designed to halt the progression of the condition.

Background

The Synergy Circulatory Support System is a micro-blood pump that provides up to 4.25 liters of blood per minute and reduces the heart’s workload, while improving blood flow to vital organs. By working with the heart’s native pumping capacity, the device is specifically targeted for treatment of ambulatory heart failure patients (INTERMACS 4,5,6 / NYHA IIIB and early IV) who remain symptomatic despite standard medical management.

The system is surgically implanted using a mini-thoracotomy and is placed in a pacemaker-like pocket. In a clinical study, Synergy improved haemodynamics, exercise capacity and overall quality of life. Synergy is designed and manufactured in Aachen, Germany.

Synergy is approximately the size of a AA battery and is implanted superficially in a pacemaker-like pocket under the right collarbone. The device is approximately 90 percent lighter than existing ventricular assist devices (VADs), and unlike VADs, implantation of Synergy is faster and does not require an open-chest procedure or cardiopulmonary bypass.

CE Marking approval was based on positive clinical results from 44 patients in an ongoing, multi-centre European trial, recently presented at the International Society for Heart and Lung Transplantation (ISHLT) meeting. A total of 59 patients have been implanted with the Synergy System in the CE Mark trial at 9 European centers.

Clinician comments

“There is currently a gap in the treatment of heart failure, with no satisfactory options available for patients who are not responding to standard medical therapy. Synergy, with its small size, minimally invasive procedure and relatively fast procedure time, is ideally suited for these patients,” said Bart Meyns, M.D., Ph.D., Professor and Chief of Cardiac Surgery at Gasthuisberg University Hospital and Principal Investigator of CircuLite’s clinical study. “In my experience with this technology, the results have been remarkable. Patients typically recover from the procedure quickly and are soon after able to perform many activities that they could not do before. This technology allows me to provide a new treatment strategy for a large number of patients who previously had no definitive options.”

Company comments

“The European approval of Synergy is a significant milestone both for CircuLite and, more broadly, for the treatment of heart failure,” said Paul Southworth, President and Chief Executive Officer of CircuLite. “SYNERGY changes the paradigm of heart failure treatment for those who are not responding to standard medical management by working as a complement to the heart’s function. The benefits are multifaceted—patients feel better, recover rapidly and are discharged quickly—which provides the potential for a cost reduction impact for hospitals. With CE Marking in place, we will begin a controlled launch of this groundbreaking advancement in select European markets.”
