Prosthetic Heart Valves And Apparatus And Methods For Delivery Of Same

A method of delivering a prosthetic heart valve to an annulus of a heart, the method comprising:

• inserting a distal end portion of a delivery sheath into an atrium of the heart, the delivery sheath having the prosthetic heart valve disposed within a lumen of the delivery sheath, the prosthetic heart valve including an outer frame and an inner frame coupled to the outer frame, the outer frame being disposed distal to the inner frame when the prosthetic heart valve is disposed within the lumen of the delivery sheath;
• moving the prosthetic heart valve distally out of the delivery sheath so that the outer frame beings to deploy from the delivery sheath prior to the inner frame deploying from the delivery sheath;
• causing the outer frame of the prosthetic heart valve to begin to transition from an inverted position in which the outer frame is disposed distal to the inner frame to a reverted position in which the outer frame at least partially surrounds the inner frame;
• and
• positioning the prosthetic heart valve within the annulus of the heart,
• wherein as the prosthetic heart valve transitions from the inverted position to the reverted position, couplers of the inner frame are received within recesses of a valve holder within the delivery sheath to prevent the inner frame from moving axially relative to the valve holder.
