Abstract

UNA PROTESIS DE LA VALVULA DEL CORAZON (1) TIENE SUSTANCIALMENTE UN CUERPO ANULAR (2) Y DOS HOJAS (3) QUE ESTAN DISPUESTAS EN EL CUERPO DE LA VALVULA (2) Y QUE, POR MEDIO DE UN MECANISMO DE BISAGRA (4, 5A, 5B), PUEDEN BASCULAR ENTRE UNA POSICION ABIERTA Y UNA POSICION CERRADA. LAS HOJAS (3) SON SEMICIRCULARES Y EVENTUALMENTE CURVADAS EN DOS DIRECCIONES PERPENDICULARES, SIENDO UNA DIRECCION PERPENDICULAR AL DIAMETRO DEL SEMICIRCULO, A MODO DE SALIENTE EXTERIOR, TAL Y COMO ES VISTA DESDE EL CENTRO DEL ANILLO (2). LOS BORDES DE LA HOJA MAS CERCANOS AL DIAMETRO DEL SEMICIRCULO ESTAN CURVADOS DE TAL MANERA QUE, CUANDO LA VALVULA ESTA CERRADA, SE APLICAN EL UNO CONTRA EL OTRO A LO LARGO DE TODA SU LONGITUD. ADEMAS, SE PROPORCIONAN DOS SALIENTES EN EL INTERIOR DEL ANILLO, EN TODA SU EXTENSION, APLICANDOSE LAS ESQUINAS (8) DE LAS HOJAS (3) CONTRA ESTOS SALIENTES CUANDO LA VALVULA ESTA CERRADA.
