Abstract: A tubular seal for a prosthetic heart valve includes an elastomeric polymer matrix and a plurality of non-elastic fibers retained within the matrix. The non-elastic fibers can be arranged in the elastomeric polymer matrix to allow the tubular seal to stretch in axial and radial directions.

Abstract: A prosthetic heart valve includes a plurality of leaflets and an expandable member including one or more braided wires with a first set of wire segments extended helically in a first direction and a second set of wire segments extended helically in a second direction such that each wire segment of the first set intersects a plurality of wire segments from the second set at a plurality of intersection points. The one or more braided wires can have crowns where the wire segments of the first set connect to wire segments of the second set. The heart valve can include a tubular seal secured to the plurality of leaflets and to the expandable member by a plurality of sutures. The sutures can include cross stitches formed around both a wire segment of the first set and a wire segment of the second set at one of the intersection points.
