Abstract: A system for treating mitral regurgitation may include an outer sheath having a lumen extending to a distal end of the outer sheath, an intermediate sheath slidably disposed within the lumen of the outer sheath, the intermediate sheath having a lumen extending to a distal end of the intermediate sheath, and an inner sheath slidably disposed within the lumen of the intermediate sheath, wherein the inner sheath includes a first anchor disposed within a lumen of the inner sheath, the first anchor being configured to penetrate and secure to a first papillary muscle. The intermediate sheath may include a tissue grasping mechanism at the distal end of the intermediate sheath, the tissue grasping mechanism being configured to hold and stabilize the first papillary muscle for penetration and securement of the first anchor to the first papillary muscle.
