Abstract

Embodiments of a prosthetic heart valve comprise an annular main body, an atrial cap extending radially outwardly from the atrial end of the main body, and a plurality of ventricular anchors extending outwardly from the ventricular end of the main body. Each ventricular anchor can have a proximal end portion connected to the ventricular end, an intermediate portion extending away from the atrial end and then back toward the atrial so as to define a first bend, and a free distal end portion that extends from the intermediate portion. The distal end portion can comprise a first section, a second section, and a second bend between the first and second sections, the first section extending from the intermediate portion in a direction toward the atrial end and radially away from the main body.

Claims23

Dependent claims

A prosthetic valve for implanting at a native mitral or tricuspid valve region of the heart, the prosthetic valve comprising:

a radially compressible and expandable frame comprising an inflow end, an outflow end, and a double-body structure having an annular inner frame and an annular outer frame, the inner frame having a main body comprising a plurality of circumferentially extending rows of angled struts and the annular outer frame having an upper portion proximate the inflow end and configured to contact an atrial face of a native valve annulus;
a plurality of prosthetic leaflets mounted within the inner frame for regulating the flow of blood in one direction through the frame;
and
a plurality of ventricular anchors, each comprising a free end portion, an intermediate portion, and a fixed end portion connected to and extending from an intersection of adjacent angled struts in one of the circumferentially extending rows of angled struts of the inner frame, the intermediate portion extending downwardly from the fixed end portion and then curving upwardly in a direction toward the inflow end such that each ventricular anchor is configured to extend behind and engage native valve leaflets in a ventricle of the heart, wherein the fixed end portion of each ventricular anchor is connected to and extends from the intersection of adjacent angled struts that forms a node spaced from an outflow end of the main body of the inner frame.

A prosthetic valve for implanting at a native mitral or tricuspid valve region of the heart, the prosthetic valve comprising:

a radially compressible and expandable frame comprising an inlet end, an outlet end, and a double-body structure having an annular inner frame portion and an annular outer frame portion circumferentially overlapping and connected to the inner frame portion, the inner frame portion and the outer frame portion, each having a main body comprising a plurality of circumferentially extending rows of angled struts, wherein the inner frame portion and the outer frame portion are attached to each other by welding, interlocking tabs, sutures, wire, or pins;
a valve structure mounted within the inner frame portion, the valve structure having a plurality of prosthetic leaflets configured to regulate the flow of blood in one direction through the frame;
and
a plurality of ventricular anchors comprising a distal end portion, an intermediate portion, and a proximal end portion connected to and extending from an intersection of adjacent angled struts in one of the circumferentially extending rows of angled struts of the inner frame proximate the outlet end, the intermediate portion extending downwardly from the proximal end portion and then curving upwardly in the direction of the inlet end such that each ventricular anchor is configured to extend behind and engage native valve leaflets in a ventricle of the heart;
wherein each ventricular anchor is connected to the inner frame portion independently from each adjacent ventricular anchor and spaced circumferentially at equal intervals around the inner frame portion.
