Abstract

1,079,979. Artificial heart valves. F. R. ALVAREZ DIAZ. Feb. 12, 1965 [April 7, 1964], No. 6217/65. Heading ASR. An artificial heart valve comprises a ring member 1 having two inwardly projecting parts 7, and a bi-convex member having two projections 9, the bi-convex member being held to the ring member 1 by the inter-engagement of the projections 7, 9 so that only limited movement sufficient to open or close the valve is possible. A band 5 of a plastics material, e.g. a mesh material, suitable for suturing and reinforced with a steel wire is secured in a groove in the ring member 1.
