Abstract
SE DESCUBRE UN CATETER (101) EPIDURAL DE UN DIAMETRO EXTREMADAMENTE PEQUEÑO, QUE ES FLEXIBLE Y NO SE ENROLLA AL FLEXIONARSE. EL CATETER (101) INCLUYE UN ESTUCHE TUBULAR O TUBO (104) QUE TIENE DENTRO UN CANAL PARA EL SUMINISTRO DE FLUIDOS AL TEJIDO BIOLOGICO. EN EL CANAL HAY UN ROLLO (105) QUE ESTA ADAPTADO EN EXPANSION PARA FORMAR UNA ESTRUCTURA DE PARED COMPUESTA QUE ES EXTREMADAMENTE FLEXIBLE Y NO SE ENROLLA. ESTA ESTRUCTURA DE PARED SE UTILIZA PARA FORMAR UN CATETER QUE TIENE UN DIAMETRO EXTERIOR PEQUEÑISIMO (106) QUE OSCILA ENTRE 0.010" A 0.032" PARA SUMINISTRAR NIVELES ACEPTABLES DE FLUIDO. EL ROLLO (105) TIENE UNA CANTIDAD DE VUELTAS SEPARADAS (110) QUE VAN DE UN EXTREMO AL OTRO DE ESTE. CERCA DEL EXTREMO FINAL DEL ROLLO (105), HAY UN NUMERO DE VUELTAS O BUCLES, SUELTOS JUNTOS (111) QUE DAN MAS FLEXIBILIDAD A ESTE EXTREMO DEL CATETER (101). EL ESTUCHE TUBULAR (104) DEL CATETER (101) TIENE UN MATERIAL DE GRAN TENSION O RESISTENCIA A LA FLEXION QUE NO SE ROMPE NI RASGA CUANDO EL CATETER(101) SE DOBLA O FLEXIONA. MANTENIENDO LA PROPORCION DEL DIAMETRO EXTERIOR (107) DEL ROLLO DE CABLE (105) CON EL DIAMETRO SECCIONAL (113) DE LAS VUELTAS INDIVIDUALES EN UN LIMITE DE 4 A 10 PREVIENE AL ESTUCHE TUBULAR (104) DE ROMPERSE O ENREDARSE CUANDO EL CATETER (101) ES DOBLADO O FLEXIONADO.
