    • PROBLEM TO BE SOLVED: To provide a fistula catheter with a simple structure and with which it is possible to suppress irritation of the wall of the alimentary canal, and a fistula catheter set. SOLUTION: This fistula catheter A which is fitted in fistulae AH and SH formed in a patient's abdominal wall AW and stomach wall SW consists of an external retention part 10 which is disposed on the abdominal wall surface AW of the fistula AH, and a tubular part 20. The tubular part 20 is arranged such that the base end part 21 links with the external retention part 10, and the tip end part 22 extends from the fistulae AH and SH into the stomach S. The tubular part 20 is formed as a flexible helix. Furthermore, the tip end part 22 of the tubular part 20 projects to the inner periphery of the helix. In addition, the angle between the central axis (a) of the external retention part 10 and the central axis (b) of the helical tubular part 20 is set to be smaller than a right angle.

    • PROBLEM TO BE SOLVED: To provide a stretcher for gastrostoma forming tube by which the operations of insertion and removal are facilitated by fixing the stretch of the gastrostoma forming tube. SOLUTION: The gastrostoma forming tube 10 is constituted of an intragastric fixing part 12 installed on the inner surface side of the gastric wall of the hole part of a patient and a tube member 11 connected to the intragastric fixing part 12 and extended to the outside of the body of the patient. The stretcher 20 for the gastrostoma forming tube to be used when inserting or removing the gastrostoma forming tube 10 to/from the hole part of the patient is constituted of a rod 21, a fixing member 22 and an engaging member 23. Then, the rod 21 is constituted of a bar-shaped member and a plurality of engaging step parts 24a are formed on the proximal end side part. Also, the fixing member 22 is made movable along the longitudinal direction of the rod 21 and an engaging projection part 35 which can be fixed to the tube member 11 is provided on the peripheral surface. The engaging member 23 is provided with a lower engaging part 26 which can be engaged with the engaging projection part 35 and an upper engaging part 27 which can be engaged with the engaging step part 24a.
