Abstract

LA INVENCION SE REFIERE A UN CATETER PARA LA INTRODUCCION DE UN MIEMBRO DE SUMINISTRO, TAL COMO UN CABLE DE GUIA QUE TENGA UN IMPLANTE ACOPLADO AL MISMO POR MEDIO DE UNA UNION ELECTROLITICAMENTE DESINTEGRABLE QUE SE ACOPLA AL ANODO DE UN SUMINISTRO DE ENERGIA QUE TIENE UN ANODO Y UN CATODO. EL CATETER COMPRENDE UN MIEMBRO TUBULAR ALARGADO QUE TIENE UNA SUPERFICIE EXTERIOR, PARTES DE EXTREMOS PROXIMO Y DISTAL, UN LUMEN QUE SE EXTIENDE ENTRE ESAS PARTES, UN ELECTRODO Y UN CONDUCTOR. EL ELECTRODO SE DISPONE DENTRO DE LA SUPERFICIE EXTERIOR DEL MIEMBRO TUBULAR EN LA PROXIMIDAD DE LA PARTE DEL EXTREMO DISTAL Y TIENE UNA SUPERFICIE QUE MIRA Y ESTA EN COMUNICACION CON EL LUMEN. EL ELECTRODO ESTA ELECTRICAMENTE ACOPLADO CON EL CONDUCTOR QUE, A SU VEZ, ESTA ADAPTADO PARA SU ACOPLAMIENTO AL CATODO DE LA FUENTE DE SUMINISTRO DE FORMA QUE CUANDO LA UNION ELECTROLITICAMENTE DESINTEGRABLE SE COLOCA EN UNA SOLUCION ELECTROLITICA, TAL COMO LA QUE SE PUEDE ENCONTRAR EN UN ANEURISMA, Y SE SUMINISTRA CORRIENTE POSITIVA DESDE LA FUENTE DE ALIMENTACION A LA UNION, LA CORRIENTE DE LA UNION PUEDE VOLVER HACIA EL CATODO DE LA FUENTE DE ALIMENTACION POR MEDIO DEL ELECTRODO. CON ESTA CONSTRUCCION, EL ELECTRODO ESTA PROTEGIDO DE LAS ESTRUCTURAS ENDOLUMINALES QUE DE OTRA FORMA INCREMENTARIAN LA RESISTENCIA EN LA LINEA DE CORRIENTE DESDE LA UNION SACRIFICIAL AL ELECTRODO. EL POSICIONAMIENTO DEL ELECTRODO EN EL CATETER SEGUN SE DESCRIBE ANTERIORMENTE PERMITE UN CAMINO DE IMPEDANCIA REPRODUCIBLE DESDE EL ELECTRODO HASTA LA ZONA DE SEPARACION, REDUCIENDO DE ESTA FORMA LA VARIABILIDAD DEL TIEMPO DE SEPARACION.
