Stented prosthetic heart valves comprising a stent frame having a compressed arrangement for delivery within a patient's vasculature and an expanded arrangement for deployment within a native heart valve. The stented prosthetic heart valves including a paravalvular leakage prevention or mitigation wrap that encircles a stent frame and is formed of a flexible material having a variable diameter defined by a greatest distance between the wrap and the stent frame. The wrap further includes a first end coupled to the stent frame and an opposing second end that is not coupled to the stent frame, wherein the wrap can selectively enlarge its diameter in situ via movement of the second end. Devices for and methods of selectively deploying the wrap are also disclosed.

Stented prosthetic heart valve having a wrap and delivery devices

Aspects of the disclosure relate to devices and methods for preparing an existing, implanted prosthetic aortic valve for subsequent prosthetic aortic valve implantation. To prepare the existing valve, a valve preparation device is delivered to the valve and valve leaflets are severed either via mechanical cutting or electrodes so that the leaflets cannot obstruct a blood flow path once a prosthetic valve is subsequently implanted within the valve. Similarly, in alternate embodiments, devices and methods of the disclosure can be used for preparing a native aortic valve for delivery and implantation of a prosthetic valve.

Devices and methods for aortic valve preparation prior to transcatheter prosthetic valve procedures

Transcatheter delivery systems, delivery catheters and associated methods for percutaneous delivery of prosthetic mitral valves using a retrograde approach are disclosed herein. A heart valve delivery system configured in accordance herewith includes a delivery catheter having an elongated tubular component and an articulation assembly at a distal end thereof. The articulation assembly includes an arm portion coupled to the tubular component by an elbow or hinge portion. In a closed, delivery state, the elbow portion positions the arm portion generally parallel to the tubular component for delivery of the delivery catheter through the vasculature. In an open, deployed state, the elbow portion positions the arm portion in a non-axial direction with respect to a longitudinal axis of the tubular component for orienting and positioning a prosthetic valve device carried by the arm portion, e.g., within the native mitral valve region.
