    • A method is described of inserting guide wires into a lumen, for example into the human gastrointestinal tract. A guide wire structure is employed which comprises at least two guide wires each having a leading end portion which terminates in a leading end, the guide wires being connected to one another by a junction at or adjacent their leading ends, the guide wires have a first position in which the leading end portions are substantially parallel to one another, a second position in which the leading end portions are curved, and a third position in which at least one of the leading end portions forms a loop. The guide wire structure is steered through the gastrointestinal tract by selectively advancing or retracting a single guide wire or advancing more than one guide wire simultaneously, according to the path which is required to be followed.
    • 描述了将引导线插入管腔,例如插入人胃肠道中的方法。 引导线结构包括至少两条引导线,每条引导线的前端部终止于前端,引导线通过其前端处或相邻的连接处彼此连接,引导线具有第一 前端部基本上彼此平行的位置,前端部弯曲的第二位置和至少一个前端部形成环状的第三位置。 根据需要遵循的路径,引导线结构通过选择性地前进或后退单根导丝或同时推进多根导丝而转向胃肠道。
