Abstract
Abstract A mitral valve staple device treats mitral regurgitation of a heart. The device includes first and second leg portions, each leg portion terminating in a tissue piercing end, and a connection portion extending between the first and second leg portions. The connection portion has an initial stressed and distorted configuration to separate the first and second leg portion by a first distance when the tissue piercing ends pierce the mitral valve annulus and a final unstressed and undistorted configuration after the tissue piercing ends pierce the mitral valve annulus to separate the first and second leg portions by a second distance which is shorter than the first distance. The device is deployed within the heart transvenously through a catheter positioned in the coronary sinus adjacent the mitral valve annulus. A tool forces the mitral valve staple device through the wall of the catheter for deployment in the heart.
