摘要：A catheter and stylet assembly in one form of the invention includes a cathetersub-assembly, a primary stylet sub-assembly and a secondary stylet sub-assembly. Thedual stylet assembly facilitates individual manipulation of the stylets to vary cathetertube stiffness as the tube is inserted through the patient's nose, stomach and duodenuminto the jejunum by a method of the invention. A catheter stylet and guide wire assemblyin another form of the invention includes a catheter sub-assembly, a stylet sub-assemblyand a guide wire. Guide wire and stylet manipulation faulitates varying catheter tubestiffness 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 touncoil in the jejunum where it serves as a peristalsis-aided anchor for the tube tip.
