Abstract

UN CATETER (1), QUE ESTA CONFIGURADO A PARTIR DE UNA MANGUERA DE PLASTICO FLEXIBLE, DISPONE EN SU INTERIOR DE UN CANAL (7) HUECO Y EN SU EXTREMO DISTANTE UNA ZONA (4) DE DESVIACION PARA PODER CONTROLAR EN EL CASO DE INTRODUCCION EN BIFURCACIONES EL ACCESO A LOS VASOS SANGUINEOS. PARA LA DESVIACION DE LA ZONA (4) SIRVE UN ELEMENTO (5) DE TRACCION QUE DISCURRE DE FORMA EXCENTRICA HACIA LA MITAD, QUE ESTA RODEADO POR UNA GUIA. EL CATETER (1) TIENE CON ELLO UNA FORMA CIRCULAR REGULAR, OVAL O SECCION TRANSVERSAL DE FORMA ELIPTICA Y EL ELEMENTO (5) DE TRACCION Y SU GUIA SON APLICABLES DENTRO DEL PERIMETRO DE SU SECCION TRANSVERSAL. CON ELLO EL CATETER SE DOBLA SOLAMENTE EN SU ZONA (4) DE DESVIO Y NO EN LA ZONA A LA QUE SE GUIA, CUANDO AL ELEMENTO (5) DE TRACCION SE APLICA UNA FUERZA DE TRACCION, MOSTRANDO EL CATETER (1) UNA ZONA (4) DE DESVIO O DE FLEXION QUE DISCURRE DE FORMA APROXIMADAMENTE PARALELA CON RESPECTO AL ELEMENTO (5) DE TRACCION, EN LA ZONA NO DESVIABLE DE APUNTALAMIENTO, PERO CON UNA CONSERVACION DE FLEXIBILIDAD INCLUSO DENTRO DE LA SECCION TRANSVERSAL DE CATETER. ESTA CONSERVACION PUEDEN DISPONERSE EN EL ELEMENTO (5) DE TRACCION COMO GUIA EN EL TUBO (8) DE GUIA DE RECEPCION DE METAL O DE PLASTICO ENDURECIDO Y/O DE UN OTRO ELEMENTO (15) DE TRACCION, QUE DISCURRE DE FORMA PARALELA CON RESPECTO AL ELEMENTO (5) DE TRACCION MOVIL QUE ESTA INSTALADO DE MODO FIJO SOBRE UN LADO DEL CATETER DE FORMA OPUESTA APROXIMADAMENTE AL DIAMETRO Y DISCURRE SOLAMENTE HASTA LA ZONA (4) DE DESVIO.
