Title
(ES) REEMPLAZO DE VALVULAS DEL CORAZON USANDO TUBOS FLEXIBLES.
Abstract
(ES)
ESTA INVENCION INCLUYE UN PROCEDIMIENTO PARA UTILIZAR UN MATERIAL TUBULAR (200) PARA SUSTITUIR UNA VALVULA CARDIACA (118, 120, 162) DURANTE CIRUGIA CARDIACA. PARA CREAR UNA VALVULA AURICULOVENTRICULAR DE SUSTITUCION (MITRAL O TRICUSPIDE) (120, 160), LA ENTRADA DEL TUBO SE SUTURA A UN ANILLO DE VALVULA (121, 162) DEL CUAL SE HAN ELIMINADO LAS PROYECCIONES NATIVAS, Y LA SALIDA DEL TUBO SE SUTURA A MUSCULOS PAPILARES (126, 128, 170) EN EL VENTRICULO (112, 152). PARA CREAR UNA VALVULA SEMILUNAR (AORTICA O PULMONAR) (118), LA ENTRADA DEL TUBO SE SUTURA A UN ANILLO DEL CUAL SE HAN ELIMINADO LAS CUSPIDES NATIVAS, Y EL TUBO SE CLAVA EN TRES PUNTOS DISTALMENTE EN EL INTERIOR DE LA ARTERIA, O SE SUTURA LONGITUDINALMENTE A LO LARGO DE TRES LINEAS; ESTO PERMITE QUE LAS PROYECCIONES DE TEJIDO ENTRE LOS TRES PUNTOS DE FIJACION EN LA SALIDA DE LA VALVULA ACTUEN COMO CUSPIDES MOVILES. ESTAS APROXIMACIONES GENERAN UNOS DISEÑOS DE FLUJO QUE IMITAN DE FORMA MUY CERCANA LOS DISEÑOS DE FLUJO DE LAS VALVULAS NATIVAS. UN MATERIAL TUBULAR PREFERIDO (200) INCLUYE TEJIDO DE SUBMUCOSAS PROCEDENTE DEL INTESTINO DELGADO; ESTE PUEDE OBTENERSE DEL MISMO PACIENTE QUE SE SOMETE A LA OPERACION CARDIACA PARA REDUCIR LA ANTIGENICIDAD. TAMBIEN PUEDE UTILIZARSE TEJIDO INTESTINAL ANIMAL O DE CADAVER SI SE TRATA DE FORMA ADECUADA, O PUEDE UTILIZARSE UN MATERIAL TUBULAR SINTETICO BIOCOMPATIBLE. ESTA INVENCION TAMBIEN DESCRIBE UN SEGMENTO DE TEJIDO INTESTINAL O UN SEGMENTO TUBULAR SINTETICO TRATADOS DE FORMA ADECUADA (500), QUE RESULTAN ADECUADOS PARA SU IMPLANTACION COMO VALVULA CARDIACA DE SUSTITUCION, CONTENIDOS DENTRO DE UN ENVASE ESTERIL SELLADO (510).
