Abstract

1327371 Valves N MACLEOD 20 Aug 1970 [21 May 1969] 26028/69 Heading F2V [Also in Division A5] Valve, which is particularly for use as a prosthetic or artificial heart valve or for other fluid control purposes, is designed to offer little resistance to or disturbance of forward flow yet to close rapidly and firmly under reverse flow or pressure gradient. One valve comprises a body 1 having a frusto-conical passageway 2 therethrough, and a valve member 3 of substantially elliptical disc form disposed, when the valve is closed, at a correspondingly shaped elliptic section of the passageway, the disc being pivotally mounted within the passageway along an axis parallel to, but spaced toward the converging end of the passageway from, the minor axis of the disc. Preferably the disc is of aerofoil section, with the leading edge nearer the converging end of the passageway. The ends of the body may terminate in oblique planes parallel to the disc, e.g. 45 degrees to the axis. The valve is provided with suitable sewing ring arrangements (not shown) for implantation.
