    • PROBLEM TO BE SOLVED: To provide a blood treatment catheter pre-assembled with a stiffening tube.
      SOLUTION: The catheter 10 includes a withdrawal lumen 16 and a supply lumen 18 each having unjoined segments of a distal split tube 22 and an intermediate joined segment 20. The split tube segment of the supply lumen is provided with a sidewall aperture. The stiffening tube extends through a withdrawal split tip tube, out the distal end of the withdrawal split tip tube, through the aperture of a supply split tip tube and through the supply split tip tube distal end of the aperture, and out the distal end of the supply split tip tube. When the stiffening tube is positioned inside the catheter, the aperture is adjacent to the withdrawal split tip tube distal opening so as to minimize the exposure of the stiffening tube and to provide a smooth exterior profile.

    • 要解决的问题:提供预先装配有加强管的血液处理导管。 解决方案:导管10包括取出内腔16和供应管腔18,每个内腔具有远端分裂管22和中间连接段20的未连接段。供应腔的分裂管段设置有侧壁孔。 加强管通过提取分流尖端管的提取分流尖端管延伸穿过供给分流尖端管的孔,并穿过供给分流尖端管远端的远端 供应分流头管。 当加强管定位在导管内时,孔与提取分离尖端管远端开口相邻,以便最小化加强管的暴露并提供光滑的外形。 版权所有(C)2004,JPO
