    Abstract: An insert for use in restraining an animal heart valve against distortion during fixation comprises a tubular peripheral wall (37) open at both ends and defining a generally axial passage (39). The peripheral wall (37) has three generally axially extending projections (41, 43, 45). Each of the projections (41, 43, 45) terminates axially outwardly in a curved end surface as viewed in side elevation, and each adjacent pair of projections (41, 43, 45) is circumferentially spaced by a recess (47). Each of the projections (41, 43, 45) has an outer tissue supporting surface (53, 55) closely adjacent its free end, the outer tissue supporting surface (53) of one of the projections (41) lying more radially outwardly of the axis of the passage (39) than the outer tissue supporting surfaces (55) of the other two projections (43, 45) so that the outer tissue supporting surfaces (53, 55) are arranged eccentrically about the axis of the passage (39). At least the exposed surface of the insert (17) is constructed by a biocompatible material.

    Abstract: An aortic prosthetic valve for supra-annular implantation comprising a valve body of generally annular configuration and a valve element movably mounted on the valve body for opening and closing the valve. The valve body terminates in a generally annular base surface, and a scalloped suture ring circumscribes the valve body adjacent the base surface. The suture ring is configured to approximately fit the contour of the Sinuses of Valsalva at the base of the aorta. The base surface of the valve body is of a wavy configuration and is configured such that it does not project into the annulus at the base of the aorta, and accordingly, the valve body does not interfere with flow through the annulus. The suture ring has three lobes which fit the Sinuses of Valsalva at the base of the aorta. The valve is configured to minimize disruption of the vortices which develop in the Sinuses of Valsalva to assist in closing the valve.
