Transcatheter aortic valve prostheses for improving the cardiac function of a patient suffering from coronary artery disease. Transcatheter aortic valve prostheses include a valve component and a frame. The valve component includes valve leaflets and a skirt. The frame includes access cells that improve access to a patient's coronary arteries if further intervention is required and/or includes a window or conduction protection cell that is oriented to align with a portion of conduction system of the heart in situ to reduce conduction disturbances of the anatomy. Suture patterns for attaching a commissure to a commissure post of the frame, and for attaching a tissue bumper to the commissure post, are also described.

Transcatheter heart valve prostheses

Stented prosthetic heart valves including a stent frame having a plurality of stent frame support structures collectively defining an interior surface, an exterior surface and a plurality of cells. The stented prosthetic heart valve further including a valve structure including valve leaflets disposed within and secured to the stent frame and defining a margin of attachment. The stented prosthetic heart valve including one or both of an outer paravalvular leakage prevention wrap and an inner skirt for supporting the valve leaflets. In various embodiments, the outer wrap is positioned entirely on one side of the margin of attachment. In embodiments including an inner skirt, the outer wrap and the inner skirt are on opposite sides of the margin of attachment such that the inner skirt and the outer wrap do not overlap. In other embodiments, the outer wrap includes a plurality of zones having varying thickness.

Stented prosthetic heart valve having a paravalvular sealing wrap

A system includes a medical device for implanting in a valve of a subject, the implantable medical device having a self-expanding frame; and a holder configured to retain the frame of the implantable medical device in a constricted configuration and to control expansion of the frame. The holder has a controllably constrictable and expandable loop, wherein the loop is disposed about at least a portion of the self-expanding frame such that constriction or expansion of the first loop controls constriction or expansion of the frame.

Valve delivery tool

Aspects of the disclosure include a prosthetic heart valve including a stent structure forming a plurality of commissure posts, a valve structure supported by the stent structure, a base supporting the stent structure and at least one radiopaque element positioned around the base. The radiopaque element can include a band extending around the base. In some embodiments the band is coiled. The band can optionally include a badge with an indicator specifying properties of the valve and viewable under fluoroscopy. In some embodiments, the radiopaque element is a badge that can have an indicator. The radiopaque elements of the disclosure increase ease and accuracy in the positioning of a percutaneously delivered replacement valve within a previously implanted valve of the disclosure.

Radiopaque elements for surgical heart valves

A delivery device for a stented heart valve includes a handle, an elongate shaft extending from a distal end of the handle, and a conical housing having a proximal end coupled to the elongate shaft and an open distal end, the conical housing having a conical lumen therein with a first internal diameter adjacent to the proximal end of the conical housing and a larger second internal diameter adjacent to the open distal end of the conical housing.

Surgical delivery device and method of use

A delivery device for a stented heart valve comprises a handle, an elongate shaft extending from a distal end of the handle, and a conical housing having a proximal end coupled to the elongate shaft and an open distal end, the conical housing having a conical lumen therein with a first internal diameter adjacent to the proximal end of the conical housing and a larger second internal diameter adjacent to the open distal end of the conical housing.

A delivery device for a stented heart valve comprises a handle, an inner catheter shaft extending from the handle and having an enlarged bumper element at a distal end, an outer catheter shaft extending from the handle and slidably coupled around the inner catheter shaft, and a retraction mechanism for controlling longitudinal movement of the outer catheter shaft relative to the inner catheter shaft. The outer catheter shaft includes a generally cylindrical housing at a distal end that is structured to receive the bumper element therein.

Transapical delivery device and method of use

A method and device for reducing paravalvular leakage upon implantation of a replacement heart valve is provided. The valve assembly includes a tissue or bioprosthetic heart valve attached to an anchoring structure. The anchoring structure includes an inlet rim that is substantially C-shaped in cross section to form a concave landing zone. The anchoring structure self-seats when implanted in the sinus of a patient with the proximal and distal ends of the C-shaped inlet rim pushed against the aorta to effectively prevent paravalvular leakage.

Anchoring structure with concave landing zone

A delivery device for a stented heart valve that includes a handle, an inner catheter shaft extending from the handle and having an enlarged bumper element at a distal end, an outer catheter shaft extending from the handle and slidably coupled around the inner catheter shaft, and a retraction mechanism for controlling longitudinal movement of the outer catheter shaft relative to the inner catheter shaft. The outer catheter shaft includes a generally cylindrical housing at a distal end that is structured to receive the bumper element therein.

A valve prosthesis includes an expandable frame. The expandable frame has an outflow portion and an inflow portion connected to the outflow portion. The frame defines a central lumen extending between the outflow portion and the inflow portion. The frame is generally cylindrical in a fully expanded configuration. When the frame is in the fully expanded configuration, an outer surface of the inflow portion is concave. The inflow portion has an upper inflow portion and a lower inflow portion. When the frame is in the fully expanded configuration, the upper inflow portion flares outwardly from the central lumen of the frame to greater extent than the lower inflow portion.
