Spacer for securing a transcatheter valve to a bioprosthetic cardiac structure

a bioprosthetic and transcatheter valve technology, applied in the field of transcatheter valve implantation, can solve the problems of insufficient expansion of the transcatheter valve inside the implanted tissue valve, the transcatheter valve is too small to be secured into some larger bioprosthetic valve sizes, and the patient's outlive the life of the valv

Benefits of technology

[0007]Considering optional features that may additionally be used, either alone or in combination with one another, the spacer may include a first flange for mounting on an upstream surface of the bioprosthetic structure and a spacer shaft. The spacer may optionally also have a second flange for mounting on the bioprosthetic structure in the downstream direction relative to the first flange. In an embodiment in which the spacer has both a first and a second flange, the spacer shaft interconnects the first flange and the second flange. As a further alternative, the spacer may have a spacer shaft secured to an interior surface of the existing biopros...

Problems solved by technology

Although the durability of bioprosthetic valves has improved, some patients outlive the life of the valve, for example, when structural deterioration causes the valve to fail.
Such transcatheter valves are too small to be secured into some larger bioprosthetic valve sizes, however.
A challenge with valve-in-valve replace...

Embodiment Construction

[0038]FIG. 1 illustrates one embodiment of a spacer ring 5 deployed in a surgical mitral or tricuspid prosthetic valve 10, for example, a Carpentier-Edwards PERIMOUNT Magna Mitral Ease® mitral heart valve (Model 7300TFX, Edwards Lifesciences, Irvine, Calif.). The spacer ring 5 is provided to narrow or reduce the space an implanted bioprosthetic mitral, tricuspid, pulmonic, or aortic valve 10 into which the transcatheter valve is to be implanted, for example, a surgically implantable bioprosthetic valve. As discussed above, the spacer ring 5 is useful in situations in which an interior space or lumen of a previously implanted prosthetic valve is too large for direct implantation of a largest available transcatheter valve therein. FIG. 2 is a top view of the same spacer ring 5 in place on the surgical mitral or tricuspid valve 10. FIG. 3 is a perspective view of the spacer ring itself, and FIG. 4 is a cross-section of the spacer ring of FIG. 3.

[0039]Considering FIG. 4, the spacer has ...

Abstract

A spacer for creating a docking station for a transcatheter heart valve is provided. The spacer changes an effective diameter and/or a shape of an implanted bioprosthetic structure such as a bioprosthetic heart valve or annuloplasty ring, providing a supporting structure into which the transcatheter valve expands without over expanding. The spacer may be deployed through an interventional technique either through transseptal access, transfemoral access, or transapical access and is typically deployed at least in part on an inflow portion of the implanted bioprosthetic structure.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of International Patent Application No. PCT / US2016 / 050254, filed Sep. 2, 2016, which claims the benefit of U.S. Patent Application No. 62 / 213,559, filed Sep. 2, 2015, the entire disclosures of which are incorporated by reference herein.TECHNICAL FIELD[0002]The present disclosure relates to transcatheter valve implantation in a bioprosthetic valve or a native valve that has been repaired with an annuloplasty ring and, in particular, an apparatus and method to assist in securing the transcatheter valve in the bioprosthetic valve or to the annuloplasty ring.BACKGROUND[0003]Valve-in-valve transcatheter valve implantation is increasingly used when bioprosthetic heart valves fail. Bioprosthetic valves are used more often than mechanical valves, and increasingly, in younger patients. Although the durability of bioprosthetic valves has improved, some patients outlive the life of the valve, for example, when stru...
