Abstract
UNA PROTESIS DE VALVULA PARA EL CORAZON ADAPTADA PARA PODER SER IMPLANTADA PERMANENTEMENTE EN SUSTITUCION A UNA VALVULA CARDIACA, DEFECTUOSA, EN DONDE EL DISPOSITIVO DE PROTESIS MEJORADO INCLUYE UN CUERPO ANULAR O ANILLO DISEÑADO PARA RETENER UN PAR DE OCLUSORES DE PLACA PLANA ROTATIVOS. LA ESTRUCTURA DE LA PRESENTE INVENCION CONTIENE MODIFICACIONES QUE MEJORAN LA DINAMICA DEL FLUJO A SU TRAVES Y REDUCEN, SI NO ELIMINAN, LA FORMACION DE REMOLINOS O AREAS DE ESTASIS EN Y A LO LARGO DE LA TRAYECTORIA DE FLUJO. EL ANILLO ANULAR TIENE PARES DE SEGMENTOS ESFERICOS COLOCADOS UNOS ENFRENTE DE LOS OTROS QUE FORMAN UNAS AREAS DE PIVOTE PARA LOS OCLUSORES, LOS CUALES TIENEN UNAS CONCAVIDADES QUE SE PUEDEN ENGANCHAR A LOS SEGMENTOS ESFERICOS. HAY UNOS RETENES PARA CONTROLAR EL GRADO DE TRAYECTORIA ARQUEADA O DE VUELTA ROTATIVA DE MOVIMIENTO. LAS SUPERFICIES DE SOPORTE SE ENCUENTRAN COLOCADAS EN UNOS LUGARES SEPARADOS DEL EJE DE ROTACION PARA ASI MEJORAR LA DISTRIBUCION DE LAS TENSIONES CREADAS DURANTEEL CIERRE. EL CANAL DE FLUJO QUE HAY A TRAVES DEL CUERPO ANULAR O DEL ANILLO ESTA DISEÑADO DE TAL MODO QUE SE EXPANDA O SE ENSANCHE DESDE EL EXTREMO DE ENTRADA DEL FLUJO AL EXTREMO DE SALIDA.
