Abstract
VALVULA CARDIACA ARTIFICIAL EN MATERIAL BIOCOMPATIBLE DEL TIPO QUE COMPRENDE UN CUERPO ANULAR (1), UNA CLAPATELA (2) ALOJADA DE FORMA PIVOTENTE EN EL INTERIOR DEL CUERPO (1) Y POSEE UNOS ELEMENTOS D UNION DESTINADOS A COOPERAR CON UNOS MEDIOS DE GUIA Y RETENCION PREVISTOS EN LA PARED LATERAL INTERNA (4) DEL CUERPO ANULAR (1). SE CARACTERIZA PORQUE LA CHAPALETA (2) ESTA CONSTITUIDA POR UN DISCO ABOVEDADO SIGUIENDO UN EJE XX''PARALELO A UNO DE SUS DIAMETROS CON UN ANGUILO COMPRENDIDO ENTRE 0 Y 30 DETAL FORMA QUE LA APERTURA DE LA VALVULA SE EFECTUA EN DOS FASES CONSECUTIVAS. LA PRIMERA FASE CORRESPONDE A UNA ROTACION DE LA CAPALETA (2) ALREDEDOR DEL PUNTO DE CONTACTO Y DE ARTICULACION A DE LA PARTE POSTERIOR (3) DE LA CHAPALETA (2) CON EL BORDE INFERIOR DE LA PARED LATERAL DE DICHO CUERPO HASTA QUE DICHOS ELEMENTOS DE UNION ESTEN EN ESTRIUBO DENTRO DE LOS MEDIOS DE GUIA Y DE RETENCION. LA SEGUNDA FASE CORRESPONDE A UNA ROTACION ALREDEDOR DE UN EJE ZZ''PARALELO AL EJE XX''HASTA QUE LA PARTEPOSTERIOR (3) DE LA CHAPALETA (2) SEA PARALELA AL EJE YY''DEL CUERPO (1).
