This is a picture of an excised mitral valve from a pig with suture and a clip holding the leaflets together in a novel approach to treating mitral valve regurgitation.  It was placed percutaneously using a specially designed catheter.  The superelastic Nitinol clip was designed and developed using Finite Element Analysis (FEA).
