Abstract: A prosthetic heart valve has a plurality of valve leaflets that control directional flow of blood through a heart and a stent structure having a plurality of commissure posts supporting the valve leaflets. The stent structure has a covering over the plurality of commissure posts and has a sewing ring at an inflow end of the stent structure. Each of the plurality of commissure posts has a tip and a suture loop is attached to the covering at a location adjacent to or on the tip of the commissure post. Each suture loop provides a passage for a suture to pass through between the covering and the suture loop.

Abstract: A sewing ring for prosthetic heart valves that is connected and configured to pivot outward. A biocompatible fabric covering surrounds at least a portion of the sewing ring, and the ring may be exclusively connected to a stent with the fabric. The sewing ring may be generally planar and of uniform thickness, or may be of varying thickness. The fabric may be used to encompass both the stent and the sewing ring, and may be a single piece. A seam may be provided in the fabric as a discrete pivoting line. The sewing ring may be convertible between bi-stable positions. The ring may extend outward in a frusto-conical shape so as to enable inversion between a position facing the inflow end of the valve and a position facing the outflow end of the valve. The sewing ring may have a compliant insert having a celled construction defined by outer walls and inner ribs. A method of implantation, and a method of assembly of the heart valve is also provided.

Abstract: A prosthetic heart valve for implant in a human. The valve includes a wireform with undulating inflow cusps and outflow commissure posts to which flexible leaflets attach and coapt in a flow area. Each leaflet may drape over the top of the wireform in the cusp area, but have tabs that each extend underneath the wireform at the commissure posts to be secured along with a tab of an adjacent leaflet. The prosthetic heart valve may also be a dual-wire wireform, with the leaflets sandwiched therebetween. One wireform may be larger than the other, with the leaflets extending over the smaller wireform. The smaller wireform may have commissures that bend radially outward from the larger wireform to provide structure to which the leaflet tabs attach.
