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.

Abstract: A valve replacement implant may include an expandable anchor member having a proximal end and a distal end, the anchor member being actuatable between a delivery configuration and a deployed configuration. A plurality of locking mechanisms may be configured to secure the anchor member in the deployed configuration. Each locking mechanism may include an axially movable post including a leg portion extending inwardly therefrom, and a receiving portion fixed to the anchor member, the receiving portion being configured to slidably receive the post. A plurality of valve leaflets may be disposed within a central lumen of the anchor member, the plurality of valve leaflets being secured to the leg portions of the plurality of locking mechanisms. The plurality of locking mechanisms may be releasably attached to a delivery device.
