Stented prosthetic heart valve having a paravalvular sealing wrap
First Claim
1. A stented prosthetic heart valve comprising:
- a tubular stent frame having a plurality of stent frame support structures collectively defining a plurality of cells, an interior surface and an exterior surface of the stent frame;
a valve structure including valve leaflets disposed within and secured to the stent frame, the valve leaflets defining a margin of attachment;
wherein the margin of attachment defines a boundary between an inflow side and an outflow side of the margin of attachment;
wherein the valve structure includes first, second and third commissure posts positioned between and supporting adjacent valve leaflets; and
an outer wrap generally encircling the exterior surface of the stent frame;
wherein the outer wrap is positioned entirely on the inflow side of the margin of attachment;
wherein the outer wrap has a U-shaped boundary that is aligned with the margin of attachment, the U-shaped boundary spanning from the first commissure post to the second commissure post.

Abstract
Stented prosthetic heart valves including a stent frame having a plurality of stent frame support structures collectively defining an interior surface, an exterior surface and a plurality of cells. The stented prosthetic heart valve further including a valve structure including valve leaflets disposed within and secured to the stent frame and defining a margin of attachment. The stented prosthetic heart valve including one or both of an outer paravalvular leakage prevention wrap and an inner skirt for supporting the valve leaflets. In various embodiments, the outer wrap is positioned entirely on one side of the margin of attachment. In embodiments including an inner skirt, the outer wrap and the inner skirt are on opposite sides of the margin of attachment such that the inner skirt and the outer wrap do not overlap. In other embodiments, the outer wrap includes a plurality of zones having varying thickness.
