    • A device and system for providing a centered lumen within a catheter body. A coiled guide lumen (CGL) is composed of a length of wire forming a plurality of coils about the longitudinal axis of the CGL, the CGL including one or more first sections having a first diameter and one or more sections having a second diameter, the second diameter being greater than the first diameter, and a secondary guide lumen extending through the first sections. The CGL may include at least one pull wire extending through the secondary guide lumen and attached at the distal portion of the catheter body. A band may be coupled to an interior of the catheter body distal portion, each of the pull wires being coupled to the annular band. Alternatively, the system may further include a shim coupled to the band, each of the pulls wire being coupled to the shim.
    • 一种用于在导管体内提供中心内腔的装置和系统。 盘绕的引导管腔(CGL)由一定长度的线材形成,所述线材围绕CGL的纵向轴线形成多个线圈,所述CGL包括具有第一直径的一个或多个第一部分和具有第二直径的一个或多个部分,所述 第二直径大于第一直径,以及延伸穿过第一部分的第二引导腔。 CGL可以包括至少一根拉线,该拉线延伸穿过第二引导腔并且附接在导管主体的远端部分。 带可以联接到导管主体远侧部分的内部,每个拉线联接到环形带。 或者,该系统还可以包括耦合到带的垫片,每个拉线耦合到垫片。
