Abstract RU 2261688 C2

FIELD: medical engineering.

SUBSTANCE: device has grooves, bevel or ledge on each cusp closure surface to guide limited reverse blood flow directly to articulated members and casing and cusp surfaces adjacent thereto. The cusps allow forced rotation about casing axis due to limited reverse blood flow tangentially arriving when having the cusps closed, to make blood volume whirl about the central axis of the casing when entering the prosthesis and opening cusps.

EFFECT: high resistance to thrombus formation; prolonged service life; high reliability; reduced load applied to patient heart.
