摘要
Apparatus and methods are described herein for use in the transvascular delivery and deployment of a prosthetic mitral valve. In some embodiments, an apparatus includes a prosthetic heart valve that includes an inner frame and an outer frame couplable to the inner frame via sutures. The prosthetic heart valve is movable between a first configuration for delivery and a second configuration when implanted in a heart. When in the first configuration, the inner frame can be disposed axially proximal of the outer frame and loosely coupled together via the sutures. When in the second configuration, the inner frame and outer frame are disposed in a nested configuration and can be secured together with the sutures. In some embodiments, the sutures are secured with slip knots. In some embodiments, a delivery device can be used to secure the slip knots and sutures to the prosthetic valve.
