Abstract

UN DISPOSITIVO (10) DE CATETER Y UN METODO PARA UTILIZAR EL MISMO Y FACILITAR LA EXTRACCION DE MATERIAL OBSTRUCTIVO EN UN CONDUCTO DEL CUERPO HUMANO. EL CATETER COMPRENDE UN CUERPO ALARGADO (12), CON UNA PORCION EXTREMA DISTANTE ADAPTABLE PARA INTRODUCIRSE EN EL CONDUCTO, Y UNA PORCION EXTREMA PROXIMA. UN LUMEN, QUE SE EXTIENDE LONGITUDINALMENTE A TRAVES DEL CITADO CUERPO DEL CATETER, SUSTENTA UN GUIAHILO (22), QUE TIENE UN EXTREMO DISTANTE A LO LARGO DEL CUAL EL CUERPO DEL CATETER PUEDE DESPLAZARSE DENTRO DEL CONDUCTO. UNA SERIE DE ELEMENTOS (14) DE FIBRAS ESCASAMENTE ESPACIADOS Y PARALELOS, SE EXTIENDEN A TRAVES DEL CUERPO DEL CATETER DESDE SU EXTREMO PROXIMO, Y TERMINAN CERCA DE UNA CARA EXTREMA DISTANTE DEL CITADO CATETER. ENERGIA LASERICA, SUMINISTRADA EN EL EXTREMO PROXIMO DEL CATETER, SE TRANSMITE A LO LARGO DE ELEMENTOS DE FIBRAS Y SE EMITE HACIA ADELANTE DESDE ALLI, EN LA CARA EXTREMA DISTANTE DEL CATETER. EN UNA VERSION, EL CATETER TIENE UNA PORCION DE BOQUILLA AHUSADA O CONICA (18) PARA EL DESPLAZAMIENTO DEL PRODUCTO OBSTRUCTIVO EN EL CONDUCTO DEL CUERPO, ANTES DE LA EMISION DE LA ENERGIA LASERICA. EN OTRA VERSION, LOS ELEMENTOS DE FIBRAS SE DESPLAZAN LONGITUDINALMENTE EN UNION, PARA CORTAR Y CAPTAR EL PRODUCTO OBSTRUCTIVO, EL CUAL SE EXTRAE DESDE EL CONDUCTO DEL CUERPO.
