Abstract
Described herein are devices and methods for mitral valve repair. The devices and methods implant a plurality of distal anchors at an annulus of the mitral valve (e.g., the posterior annulus) and tension artificial chordae to pull the portion of the annulus toward an opposite edge and inward into the ventricle. This can effectively reduce the size of the orifice and increase coaptation. The delivery devices can be configured to be actuated to form a distal anchor made of a pre-formed knot. The delivery devices deliver the pre-formed knot in an elongate configuration. Actuation of the delivery device causes the pre-formed knot to transition from the elongate configuration to the deployed configuration by approximating opposite ends of a suture coupled to a coiled configuration to form one or more loops. After formation of the knot, the delivery device can be withdrawn.
