SCR Development Group Inc is a medical device company organized around development of innovative, minimally invasive cardiovascular devices. One of the largest unsolved problems in cardiac care affecting more than 5 million patients in US alone, is conegstibe heart failure. Despite advancements in medical therapies, many congestive heart failure iatients will eventually deteriorate to the point where they require mechanical circulatory support. Most current mechanical circulatory support devices require an sternotomy, a major surgical procedure and use a cardiopulmonary bypass for implantation. Despite the fact that the intra aortic balloon pump (IABP) has been used successfully for more than twenty years for short-term treatment of cardiac dysfunction, there is no long-term counterpulsation therapy currently available. IABP is the most widely used mechanical cardiac support device with more than 150,000 available however the IABP insertion methodology, location and the biocompatibility of the IABP catheter limits its application to short durations. The SCR-developed Symphony offers the traditional benefits of IABP in a long-term device to treat heart failure patients responsive to a milder form of cardiac assistance. The Symphony is designed for superficial implantation without the need to enter the chest. The device is a valveless, pneumatically driven blood sac that fits ergonomically in a "pacemaker pocket" with the conduit connected to the subclavian artery. The device operates using a small, wearable pneumatic driver connected to the sac by a percutaneous airline and timed to the patientâs ECG. The device fills during the heart's natural expansion to lower the muscle's workload, then ejects during natural contraction to increase blood flow throughout the body resulting in an overall improvement of patient's health
