  • Patent number: 11337800
    Abstract: The disclosure relates to heart valve prostheses with the reduced need of pacemaker implantation and improved means for positioning the replacement heart valve. In one aspect of the present disclosure, the stent scaffold of the valve prosthesis includes axially extending locators. The locators may be positioned within the cusp of the native aortic valve. Placement of the locators within the cusps may prevent further proximal movement of the stent scaffold into the left ventricle. By adjusting the location of the proximal end of the locators with respect to the proximal end of the stent scaffold, infra-annular placement of the stent scaffold in the aortic annulus may be assured. In another aspect, means for visualizing the positioning of replacement heart valves at an implant site inside an individual's body is disclosed.

  • Publication number: 20220031454
    Abstract: A method of placing an implant including a stent at a native heart valve site includes orienting an expandable body of the stent such that a first open end of the stent is upstream a second open end of the stent relative to a direction of blood flow through a native heart valve. The native heart valve includes native leaflets and an annulus. The method also includes radially expanding a plurality of positioning arches positioned around an outer perimeter of the expandable body. The method additionally includes inserting the plurality of positioning arches respectively within a plurality of pockets defined by leaflets of the native heart valve and a heart structure from which the native leaflets extend. The method further includes radially expanding the first open end of the stent into a position upstream of the annulus and out of contact with nerve bundles.
