The paper focuses on non-destructive inspection of Björk-Shiley Convexo Concave artificial mechanical heart valves. A new approach for the inspection based on sweep frequency eddy current testing is proposed. The standard self inductance pancake probe positioned in proximity of the valve drives the eddy currents and pick-ups the response signal. The frequency of exciting current is changed in a wide range. Numerical simulations are carried out to verify the usefulness of the proposed technique. The gained results presented in the paper show that there is a clear difference in the amplitude frequency spectrum of the response signal between the intact valve and the other with a single leg fracture of the outlet strut.
