    摘要： A multiple-lumen catheter is disclosed that includes a catheter tube (11) having a generally elongate cylindrical body (21) having an axial passageway (31) extending the length thereof. A septum (22) extends across the interior of the body (37) and along the length thereof in order to divide the body (21) into first (23) and second (24) lumens. A bolus (20) extends from a distal end (15) of the body. The bolus (20) has a passage section including an axial passage portion (46) and a radial passage portion (47). The axial passage portion (46) is in fluid communication with the first (23) and second (24) lumens. The radial passage portion (47) includes a single port (48) through the side of the bolus (20) whereby the first (23) and second (24) lumens are in fluid communication with the port (48). According to another form of the invention, the radial passage (247) includes a first port (249) and a second port (250) therein.

    摘要： A catheter and stylet assembly in one form of the invention includes a catheter sub-assembly, a primary stylet sub-assembly and a secondary stylet sub-assembly. The dual stylet assembly facilitates individual manipulation of the stylets to vary catheter tube stiffness as the tube is inserted through the patient's nose, stomach and duodenum into the jejunum by a method of the invention. A catheter stylet and guide wire assembly in another form of the invention includes a catheter sub-assembly, a stylet sub-assembly and a guide wire. Guide wire and stylet manipulation faulitates varying catheter tube stiffness to obtain similar results. A section of the catheter tube may be normally coiled, whereby it can be straightened for insertion into the jejunum and then permitted to uncoil in the jejunum where it serves as a peristalsis-aided anchor for the tube tip.

    摘要翻译： 本发明的一种形式的导管和探针组件包括导管子组件，主探针子组件和辅助探针子组件。 当通过本发明的方法将管穿过患者的鼻子，胃和十二指肠插入空肠时，双探针组件有助于个体操纵风格以改变导管管刚度。 本发明另一种形式的导管探针和导丝线组件包括导管子组件，探针子组件和导丝。 引导线和探针管操作可改变导管管刚度，获得类似的结果。 导管管的一部分可以通常盘绕，从而可将其拉直以插入空肠，然后允许在空肠中开卷，其中它用作管尖的蠕动辅助锚。
