System for mitral valve repair and replacement

A heart valve device comprising:

• a first assembly having a first pair of first arm members pivotally coupled to a second pair of second arm members at a first link and a second link, wherein the first arm members are coupled together at a first joint and the second arm members are coupled together at a second joint, the first assembly having a low-profile delivery configuration and an expanded deployed configuration such that the first and second links are spaced laterally apart from each other by lengths of the first and second arm members;
• and
• a second assembly having a third pair of third arm members pivotally coupled to a fourth pair of fourth arm members at a third link and a fourth link, wherein the third arm members are coupled together at a third joint and the fourth arm members are coupled together at a fourth joint, the second assembly having a low-profile delivery configuration and an expanded deployed configuration such that the third and fourth links are spaced laterally apart from each other by lengths of the third and fourth arm members,
• wherein the first and second assemblies in the deployed configuration are configured to clamp native valve leaflets and/or a native annulus therebetween,
• wherein, in the expanded deployed configuration, the first arm members and second arm members together define an interior arcuate surface configured to face away from a heart wall and an exterior arcuate surface configured to face towards the heart wall such that the first assembly defines an arcuate element configured to approximate a periphery of a portion of the native annulus.
