A feeding tube and method for introducing a feeding tube within the gastrointestinal tract of a patient, whereby the feeding tube is introduced by- using a variation of the Ponsky "pull" method of feeding tube placement. The feeding tube (10) comprises an elongate shaft (12) having a distal end and proximal end. The feeding tube also comprises a coupling structure (26) for coupling the feeding tube to a pull wire (22), the coupling structure be proximal of the distal end (16) of the feeding tube shaft. The feeding tube further comprises a guiding structure (28) for aligning the pull wire with the distal end of the shaft. The feeding tube is introduced within the patient by attaching the previously placed pull wire to the coupling and guiding structures of the feeding tube, and then pulling the pull wire so as to pull the feeding tube into and through the gastrointestinal tract of the patient.

L'invention concerne un tube d'alimentation et un procédé pour introduire un tube d'alimentation dans le tractus gastro-intestinal d'un patient, le tube d'alimentation étant introduit par une variation du procédé de retrait Ponsky du procédé de placement "par tirage" du tube d'alimentation. Le tube d'alimentation (10) comprend une tige allongée (12) possédant une extrémité distale et une extrémité proximale. Le tube d'alimentation comprend aussi une structure de raccord (26) pour raccorder le tube d'alimentation à un fil de retrait (22), la structure de raccord étant proximale par rapport à l'extrémité distale (16) de la tige du tube d'alimentation. Le tube d'alimentation comprend également une structure de guidage (28) destinée à aligner le fil de retrait sur l'extrémité distale de la tige. On introduit le tube d'alimentation dans le corps du patient par la fixation du fil de retrait relié préalablement à la fixation et aux structures de guidage du tube d'alimentation, puis on tire le fil de retrait de manière à tirer le tube d'alimentation dans le tractus gastro-intestinal du patient et à travers celui-ci.
