Abstract
Official abstract text for this publication.
A prosthetic heart valve having an inflow end and an outflow end includes a collapsible and expandable stent having a plurality of commissure features, a plurality of first struts and a plurality of second struts. The plurality of first struts define a substantially cylindrical portion and the plurality of second struts have first ends attached to the cylindrical portion and free ends projecting radially outward from the cylindrical portion and configured to couple to adjacent heart tissue to anchor the stent. A collapsible and expandable valve assembly disposed within the stent has a plurality of leaflets coupled to the commissure features.
First claim
Opening claim text (preview).
The invention claimed is: 1. A prosthetic heart valve having an inflow end and an outflow end, comprising: a collapsible and expandable stent including a plurality of commissure features, a plurality of first struts defining a substantially cylindrical portion, a plurality of curled second struts having first ends attached to the cylindrical portion and free ends projecting radially outward from the cylindrical portion to anchor the stent to the heart tissue, the free ends of a first group of the plurality of second struts have a first polarity and the free ends of a second group of the plurality of second struts have a second polarity opposite the first polarity; and a collapsible and expandable valve assembly disposed within the stent and having a plurality of leaflets coupled to the commissure features. 2. The prosthetic heart valve of claim 1 , wherein the valve assembly and the stent are capable of replacing the function of at least one of a native mitral valve or a native tricuspid valve. 3. The prosthetic heart valve of claim 1 , wherein the first ends of the first group of the plurality of second struts are disposed adjacent the outflow end. 4. The prosthetic heart valve of claim 3 , wherein the first ends of the second group of the plurality of second struts are disposed adjacent the inflow end. 5. The prosthetic heart valve of claim 4 , wherein the free ends of the first group of the plurality of second struts are configured to magnetically clamp to the free ends of the second group of the plurality of second struts on opposite sides of the heart tissue.
