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.

Abstract: A replacement heart valve system may include a replacement heart valve implant including an expandable framework configured to shift from a radially collapsed configuration to a radially expanded configuration and a plurality of valve leaflets attached to the expandable framework at a plurality of commissure posts, and an implant delivery system including a handle and an elongate shaft assembly, the elongate shaft assembly including a tubular member fixedly attached to the handle, and an implant holding portion configured to constrain the expandable framework in the radially collapsed configuration. The elongate shaft assembly includes an anti-migration element configured to shift between a delivery configuration and an open configuration. The anti-migration element is configured to prevent proximal movement of the expandable framework relative to the tubular member in the open configuration.

Abstract: 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.

Abstract: A delivery catheter as disclosed herein may be configured in various embodiments to minimize the potential for entanglement between cardiac repair components such as between sutures and coupled anchors. In various embodiments this is achieved by separating an anchor translation channel from a suture translation channel while maintaining the coupling between the anchor and the suture.
