Abstract

UNA PROTESIS DE VALVULA CARDIACA. UN CUERPO DE VALVULA (12) CON UN PASO CENTRAL (18) CON DOS LAMINAS (14,16) CADA UNA DE LAS CUALES ES PIVOTANTE SOBRE UN EJE EXCENTRICO (P,P'') EN EL PASO (18) MOVIENDOSE ENTRE UNA POSICION CERRADA Y OTRA ABIERTA. DICHAS LAMINAS (14,16) SON CURVADAS EN UN PLANO PERPENDICULAR AL EJE EXCENTRICO Y DISPUESTAS CON EL LADO ONVEXO (26,28) DE LAS LAMINAS ENCARADAS ENTRE SI EN POSICION ABIERTA. SE SELECCIONAN VARIOS PARAMETROS TALES COMO LA CURVATURA DE LAS LAMINAS (14,16), LA SITUACION DE LOS EJES (P,P'') Y EL ANGULO MAXIMO DE APERTURA EN LAS LAMINAS (14,16). **FIG.**
