Abstract

PROTHESE DE VALVULE CARDIAQUE REVETUE TOTALEMENT DE CARBONE PYROLYTIQUE. CETTE PROTHESE COMPREND UN CORPS10 DELIMITANT UN PASSAGE POUR LE SANG ET DEUX MINCES PLAQUETTES11, 12 ARTICULEES SUR LE CORPS DE FACON A REGLER L'ECOULEMENT DU SANG A TRAVERS LE PASSAGE. LA LIAISON ARTICULEE ENTRE LE CORPS10 ET LES PLAQUETTES11, 12 EST FORMEE PAR DES CAVITES PREVUES DANS LE CORPS ET DES SAILLIES31 PREVUES SUR LES PLAQUETTES. LES EXTREMITES DES CAVITES ET DES SAILLIES PRESENTENT LA FORME DE SURFACES DE REVOLUTION DE PREFERENCE SPHERIQUE. LA VALVULE EST ASSEMBLEE EN DEFORMANT ELASTIQUEMENT LE CORPS POUR PERMETTRE L'INTRODUCTION DES SAILLIES DANS LES CAVITES.HEART VALVE PROSTHESIS TOTALLY COATED WITH PYROLYTIC CARBON. THIS PROSTHESIS INCLUDES A BODY10 DELIMING A PASSAGE FOR THE BLOOD AND TWO THIN PLATES11, 12 ARTICULATED ON THE BODY SO AS TO ADJUST THE FLOW OF BLOOD THROUGH THE PASSAGE. THE ARTICULATED LINK BETWEEN THE BODY10 AND THE PLATES11, 12 IS FORMED BY CAVITIES PROVIDED IN THE BODY AND PROJECTIONS31 PROVIDED ON THE PLATES. THE ENDS OF THE CAVITES AND THE SURFACES SHOW THE FORM OF SURFACES OF REVOLUTION OF SPHERICAL PREFERENCE. THE VALVE IS ASSEMBLED BY ELASTICALLY DEFORMING THE BODY TO ALLOW THE INTRODUCTION OF PROJECTS INTO THE CAVITES.
