Abstract

UN CATETER QUE SOPORTA ELECTRODOS (10) COMPRENDE UN TUBO ALARGADO, FLEXIBLE (12) QUE DEFINE UN EXTREMO PROXIMO (14), UN EXTREMO DISTAL (16), Y UNA CAPA TUBULAR EXTERNA, ELECTRICAMENTE AISLANTE (20) INTERMEDIA A LOS EXTREMOS. EL TUBO INCLUYE UN NUCLEO FLEXIBLE, ELECTRICAMENTE CONDUCTOR (42) DE ALAMBRE Y UNA CAPA DE CUBIERTA DEL NUCLEO FLEXIBLE, ELECTRICAMENTE NO CONDUCTORA (44) DE PLASTICO ALREDEDOR DEL NUCLEO. AL MENOS UN ELECTRODO DE ANILLO ELECTRICAMENTE CONDUCTOR (30A) SE ENCUENTRA ONDULADO Y NIVELADO CON LA SUPERFICIE EXTERIOR DEL TUBO. PARA CONDUCIR LAS SEÑALES ELECTRICAS ENTRE EL EXTREMO PROXIMO (14) Y CADA UNO DE LOS ELECTRODOS DE ANILLO (30A), UNA PLURALIDAD LONGITUDINALMENTE SEPARADA DE CABLES FLEXIBLES, ELECTRICAMENTE CONDUCTORES (45) ESTAN ENROLLADOS HELICOIDALMENTE Y AL MENOS PARCIALMENTE DENTRO DE LA CAPA DE CUBIERTA DEL NUCLEO (44). LOS CABLES ENROLLADOS TIENEN CADA UNO UNA SECCION EXPUESTA (47) POR DEBAJO DE UN SEGMENTO DE CADA UNO DE LOS ELECTRODOS DE ANILLO (30A). SE DISPONE UNA CINTA PLANA, FLEXIBLE, ELECTRICAMENTE CONDUCTORA (51) DE FORMA INTERMEDIA A CADA UNO DE LOS ELECTRODOS DE ANILLO (30) Y EL TUBO CADA CINTA SE ENCUENTRA ELECTRICA Y FISICAMENTE UNIDA A UNO DE LOS RESPECTIVOS CABLES ENROLLADOS Y ENROLLADA ALREDEDOR DE LA SUPERFICIE EXTERIOR TUBULAR (20), Y CADA UNO DE LOS ELECTRODOS DE ANILLO SE ENCUENTRA ESTAMPADO SOBRE UNA DE LAS CINTAS RESPECTIVAS Y LA SUPERFICIE TUBULAR EXTERIOR. UN ELECTRODO FINAL (30B) PUEDE ESTAMPARSE SOBRE EL EXTREMO DISTAL (16) DEL TUBO (12), EN CONTACTO ELECTRICO CON UNA EXTENSION (42A) DEL NUCLEO DE ALAMBRE (42).
