Embodiment Construction

[0039] The prosthetic heart valves described herein each comprise an internal (as opposed to being a complementary element, which means incorporated into the valve itself) stent or frame, which is generally tubular in shape and defines a flow orifice region through which blood flows. The orifice area flows from the inflow end to the outflow end. Alternatively, the shape of the inner stent may be oval, oval, irregular, or any other desired shape. The valve preferably includes flexible leaflets that selectively allow fluid flow therethrough. Thus, the flow orifice area may be alternately opened and closed by movement of the leaflet. Heart valves may also include an outer or peripheral sewing or sealing ring formed of a soft, suture-penetrable material, which is typically used as an anchor to secure the valve to the native annulus, but can also be used primarily for Seal to prevent paravalvular leakage.

[0040] As mentioned herein, prosthetic heart valves used in accordance w...

Abstract

The present invention relates to a prosthetic heart valve configured to replace a natural heart valve and to expand after implantation and having a valve type indicator thereon which, after implantation, is removed from Visible in vitro. The indicator conveys information about the valve, such as the valve size or orifice diameter, and/or conveys that the valve has the ability to expand after implantation. The indicator may be an alphanumeric or other symbol or combination of symbols representing information about a valve characteristic, such as valve size. The ability to expand after implantation facilitates valve-in-valve procedures where the valve type indicator conveys information to the surgeon as to whether the implanted valve is suitable for the procedure and informs the surgeon of the choice of a second valve.

Description

technical field [0001] The present disclosure relates to surgical heart valves for heart valve replacement, and more particularly to surgical heart valves having indicators that are visible from outside the body after implantation. Background technique [0002] The heart is a hollow muscular organ with four pumping chambers and four heart valves: the aortic, mitral (or bicuspid), tricuspid and pulmonary valves. Heart valves consist of a dense, fibrous ring called the annulus, and leaflets, or cusps, attached to the annulus. [0003] Heart valve disease is a common condition in which one or more valves of the heart do not function properly. Diseased heart valves can be classified as stenotic, in which the valve does not open sufficiently to allow proper forward flow of blood through the valve, and / or insufficient, in which the valve does not close completely, resulting in Excessive backflow of blood through the valve. Valve disease can be severely debilitating and even fat...
