Abstract
Official abstract text for this publication.
A heart valve that can be expanded following its implantation in a patient, such as to accommodate the growth of a patient and the corresponding growth of the area where the valve is implanted, and to minimize paravalvular leakage. In one aspect, the invention may maximize the orifice size of the surgical valve. The invention includes expandable implantable conduits and expandable bioprosthetic stented valves. In one aspect of the invention, the valve may be adapted to accommodate growth of a patient to address limitation on bioprosthetic valve lifespans.
First claim
Opening claim text (preview).
What is claimed is: 1. A prosthetic heart valve comprising: a valved conduit comprising: a generally tubular structure comprising a proximal end, a distal end, and a central portion between the proximal and distal ends, wherein a length of the tubular structure adjacent to at least one of the proximal and distal ends has a larger diameter in its unexpanded condition than a diameter of the central portion in its unexpanded condition; and at least one leaflet attached within an…
