Sequential Delivery Of Two-Part Prosthetic Mitral Valve
First Claim
1. An apparatus, comprising:
- a prosthetic heart valve that includes an inner frame and an outer frame coupleable to the inner frame via at least one suture,the inner frame and the outer frame can be moved between a first position relative to each other in which the outer frame is disposed substantially axially proximal of the inner frame and a second position relative to each other in which the inner frame is nested substantially within an interior portion of the outer frame,the prosthetic valve movable between a first configuration for delivery into a heart of a patient and a second configuration when implanted in the heart, the prosthetic valve being in the first configuration when the inner frame and the outer frame are in the first position relative to each other, the prosthetic valve being in the second configuration when the inner frame and the outer frame are in the second position relative to each other.

Abstract
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.

6. A method, comprising:
-
inserting into a heart of a patient, a prosthetic heart valve that includes an inner frame and an outer frame coupleable to the inner frame via at least one suture, during the inserting the outer frame is disposed at least partially axially proximal of the inner frame and the inner frame and the outer frame are each in a collapsed configuration; deploying the prosthetic heart valve within the heart such that the inner frame is moved to an expanded configuration within the heart and the outer frame is at least partially moved to an expanded configuration within the heart, after the deploying, moving the outer frame and the inner frame relative to each other into a nested configuration in which the inner frame is disposed substantially within an interior portion of the outer frame. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A method, comprising:
-
inserting a prosthetic heart valve into a lumen of a delivery sheath, the prosthetic heart valve including an inner valve assembly and an outer frame assembly coupleable to the inner valve assembly via at least one suture, the prosthetic heart valve being inserted into the lumen of the delivery sheath with the inner valve assembly disposed at least partially distally of the outer frame assembly; disposing a distal end portion of the delivery sheath in a left atrium of a heart; deploying the inner valve assembly into the left atrium of the heart such that the inner valve assembly assumes a biased expanded configuration; deploying at least a portion of the outer frame assembly into the left atrium of the heart such that the at least a portion of the outer frame assembly assumes a biased expanded configuration; moving the inner valve assembly and the outer frame assembly into a nested configuration in which the inner valve assembly is at least partially disposed within a portion of the outer frame assembly; and securing the inner valve assembly to the outer frame assembly with the at least one suture. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
