Abstract
A bi-leaflet prosthetic heart valve, comprising an annular body having an upstream edge, a downstream edge and a passageway therebetween includes first and second leaflets pivotally mounted in the annular body. Each leaflet has an upstream edge, a downstream edge and a leaflet length therebetween. First and second pivot axes associated respectively with the first and second leaflets are provided and each leaflet rotates about its respective pivot axes between an open position allowing blood flow through the passageway of the annular body and a closed position blocking blood flow. The valve is configured such that the leaflets have an angle in the naturally open position of more than about 85°.
