In 1982, Ken along with his artificial heart department peers, left Aerojet and created Nimbus Inc., a small research and development company dedicated to the advancement of artificial hearts and blood pumps. Under Ken’s leadership, Nimbus Inc. persevered through years of research, grant proposals, clinical trials, venture capital overviews and multiple medical device company takeovers, to develop the left ventricle assistance device known as HeartMate 2. The HeartMate2 has been widely used around world and to date has saved 25,000 lives and counting. Ken had the rare privilege to take a project from inception to a life saving end product.
