Prosthetic Heart Valve Having Tubular Seal
First Claim
1. A prosthetic heart valve comprising:
- an expandable member comprising one or more braided wires, the one or more braided wires comprising 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, wherein the one or more braided wires have crowns where the wire segments of the first set connect to wire segments of the second set;
a plurality of leaflets being secured within the expandable member; and
a tubular seal comprising an elastomeric material, the tubular seal having an inflow edge being secured to bottom inflow edges of the plurality of leaflets and to the expandable member by a plurality of sutures, characterized by the sutures comprising 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.

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.

15. A prosthetic heart valve comprising:
-
an expandable member comprising one or more braided wires, the one or more braided wires comprising a first set of wire segments and a second set of wire segments 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; a plurality of leaflets being secured within the expandable member; and a tubular seal comprising an elastomeric material, the tubular seal having an inflow edge being secured to bottom inflow edges of the plurality of leaflets and to the expandable member by a plurality of sutures, wherein the sutures comprise 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; wherein the tubular seal comprises an outflow end region and an inflow end region, the inflow end region being a portion of the tubular seal comprising a fabric within a matrix of an elastomeric matrix, wherein the fabric has a non-linear edge defining an interface between the inflow end region and the outflow end region. - View Dependent Claims (16, 17, 18, 19)

20. A method of making a tubular seal of a prosthetic heart valve, the method comprising:
-
forming a tubular seal that includes a fabric within a matrix by dipping a mandrel with a first coating composition comprising at least one elastomeric polymer; drying the first coating composition; positioning the fabric on the mandrel; applying a second coating composition on the mandrel, the second coating composition being different than the first coating composition; and removing the tubular seal from the mandrel.
