Details and patient eligibility


The purpose of this study is to evaluate the safety and performance of the Harpoon Medical device. It is anticipated, that the Harpoon Medical device will provide advantages over current surgical interventions including: 1) a small minimally invasive incision, 2) no sternotomy, 3) no cardiopulmonary bypass, 4) no aortic manipulation, 5) a direct path to the valve plane, 6) performed on a beating heart, 7) real-time TOE-guided chordal length adjustment and 8) less complicated procedure that is teachable and adoptable.

Full description

The device is designed to reduce the degree of mitral regurgitation by delivering and anchoring artificial chordae tendineae to the affected mitral valve leaflet(s) in a beating heart.
