    • An adjustable infusion catheter (600) includes a flexible tube (602) containing one or more axial lumens (120) that allows fluid to flow from the proximal end of the catheter (600) to the distal end. A syringe (608) or infusion pump (700) is the usual pressure source for fluid at the proximal end. A plurality of small-diameter holes (160) are provided in a fenestrated area (165) near the distal end of the tube (602) to disperse fluid throughout a targeted region (800) within the patient's body. The length of the fenestrated area (165) of the catheter body (100) is adjusted by a slidable sheath (200) which can be positioned along the length of the fenestrated area (165) so that its exposed length substantially matches the targeted region (800). The ends of the slidable sheath (200) include a seal portion (167) to prevent leakage around the ends of the sheath (200). Heat shrinkable plastic material can be used to form the sheath (200) and the end seals.
    • 可调节输注导管(600)包括容纳允许流体从导管(600)的近端流到远端的一个或多个轴向腔(120)的柔性管(602)。 注射器(608)或输液泵(700)是用于近端流体的通常压力源。 多个小直径孔(160)设置在靠近管(602)的远端的开窗区域(165)中,以将流体分散在患者体内的目标区域(800)内。 导管主体(100)的开窗区域(165)的长度通过可沿着开窗区域(165)的长度定位的可滑动护套(200)来调节,使得其暴露长度基本上与目标区域 800)。 可滑动护套(200)的端部包括密封部分(167),以防止围绕护套(200)的端部的泄漏。 热缩塑料可用于形成护套(200)和端部密封。
