Abstract
Systems for mitral valve repair are disclosed where one or more mitral valve interventional devices may be advanced intravascularly into the heart of a patient and deployed upon or along the mitral valve to stabilize the valve leaflets. The interventional device may also facilitate the placement or anchoring of a prosthetic mitral valve implant. The interventional device may generally comprise a distal set of arms pivotably and/or rotating coupled to a proximal set of arms which are also pivotably and/or rotating coupled. The distal set of arms may be advanced past the catheter opening to a subannular position (e.g., below the mitral valve) and reconfigured from a low-profile delivery configuration to a deployed securement configuration. The proximal arm members may then be deployed such that the distal and proximal arm members may grip the leaflets between the two sets of arms to stabilize the leaflets.

- A method for the treatment of conditions affecting the mitral valve, comprising;
positioning a first assembly having a first pair of arm members pivotably coupled to a second pair of arm members in a subannular position; reconfiguring the first assembly from a low-profile delivery configuration to an expanded curved configuration against a subannular surface of the mitral valve; positioning a second assembly having a third pair of arm members pivotably coupled to a fourth pair of arm members in a supra-annular position; and reconfiguring the second assembly from a low-profile delivery configuration to an expanded curved configuration against a supra-annular leaflet surface such that valve leaflets and/or annulus are compressed between the first and second assemblies. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38)
