Abstract

Cover anti-thrombogenic covers for cardiac valvular prostheses of mechanical type, whose purpose is to isolate from blood contact the suture ring and points or fixation knots of the valve to the patient's own ring, and becoming an electronegative material or neutral to suppress the electrical interface caused by the positivity of the aforementioned suture ring and by the threads that form the fixing points or knots; essentially it is characterized because it is constituted by a laminar body as a ring or crown in which there are three inverted conical zones or parts whose upper zone defines a thickened and arched rim by which the self-fixation is facilitated, once inverted, a part or intermediate zone of cylindrical configuration and a third part or lower zone arched and refuted to the outside of arched form; it being provided that the flange of the upper part or zone is inverted over the suture ring of the patient, while the intermediate part or area remains in contact with the throat of the valve support ring, supporting the other face of such area or intermediate part on the suture ring itself, on the atrial side; with the particularity that the zone or lower part covers the part of the suture ring corresponding to the ventricular side of the valve, in such a way that the entire suture ring and the fixing knots are completely covered, except for the lower area of the ring that will remain in contact with the endocardium.
