A cardiac medical device from Sunshine Heart that uses a balloon to assist the heart in pumping blood has shown promise in a clinical trial led by Ohio State University Medical Center (OSUMC). Patients enrolled in a multicenter North American clinical trial of Eden Prairie, Minnesota-based Sunshine Heart’s C-Pulse heart-assist system saw improvement in a number of indicators, according to a statement from OSUMC. “The trial results to date show positive trends of efficacy with a strong safety profile as compared to later stage mechanical support devices,” said Dr. William T. Abraham, director of the division of cardiovascular medicine at OSUMC, and national co-lead principal investigator of the study.
