Problems solved by technology

In addition, all perforations and resulting sutures threaded therethrough are exposed to blood flow and are precisely positioned at the leaflet's deflection line at the leaflet base, which can lead to reduced durability

Abstract

The invention relates to a valved conduit. The valved conduit includes a leaflet construct coupled between two portions of a conduit. Each leaflet has a free edge and a leaflet attachment edge. The leaflet attachment edge is disposed between a first conduit distal end and a second conduit proximal end that are coaxial therebetween defining a junction.

Description

technical field [0001] The present disclosure relates generally to prosthetic valves, and more particularly to conduits having valve structures therein. Background technique [0002] Various manufacturing techniques have been used to couple the leaflets to the interior of the duct, including suturing the individual leaflets to the inner surface of the duct. In many cases, the resulting leaflets are supported on the inner surface of the conduit and define a valve having a mounting edge where the leaflet is coupled to the inner surface of the conduit and a free edge that allows movement of the valve. The valve moves under the influence of fluid pressure. In operation, the leaflets open to allow flow through the conduit when upstream fluid pressure exceeds downstream fluid pressure, and close and prevent flow through the conduit when downstream fluid pressure exceeds upstream fluid pressure. [0003] The process of fitting the leaflets to the inner surface of the duct is tedi...
