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.

A medical device system may include a delivery device including an outer sheath and an inner shaft having a coupler fixed to a distal end of the inner shaft, and a replacement heart valve implant releasably attached to the coupler, the replacement heart valve implant including an expandable anchor member and a plurality of locking mechanisms configured to engage with the coupler. The delivery device may include a plurality of collars configured to secure the coupler to the plurality of locking mechanisms. The delivery device may include a stop element configured to selectively prevent disengagement of the plurality of collars from the plurality of locking mechanisms.

Replacement heart valve delivery device

A replacement heart valve system may include a delivery sheath and a replacement heart valve. The replacement heart valve may include a mesh anchor member disposed within the delivery sheath in an elongated delivery configuration, the mesh anchor member being expandable to a deployed configuration when unconstrained by the delivery sheath. The mesh anchor member may include an upstream chamber, a downstream chamber, and a tubular middle portion extending between the upstream chamber and the downstream chamber. The replacement heart valve may include a diaphragm disposed within the downstream chamber of the mesh anchor member, wherein the diaphragm is configured to selectively prevent fluid flow through the replacement heart valve.
