The invention provides a catheter system comprising a stomach probe for gastric decompression or drainage of stomach fluids, and a jejunal probe for nutriment supply during enteral feeding. The stomach probe comprises a drainage tube to be inserted into the stomach of a patient, the drainage tube having proximal and distal ends and defining a lumen for receiving and for guiding insertion of the jejunal probe into the small intestine of the patient. The jejunal probe comprises a feeding tube to be inserted into the small intestine of a patient and defines a lumen for conveying liquid nutriment from an inlet at a proximal end thereof to one or more outlet openings formed at a distal end region of the feeding tube. The jejunal probe is sized and adapted to be received within the lumen of the stomach probe for guided insertion to the small intestine. The catheter system further comprises support means for supporting the jejunal probe within the lumen of the stomach probe such that the feeding tube maintains a spaced relation to an inner wall surface of the lumen of the drainage tube. The support means is typically provided over a longitudinal extent of the catheter system and comprises at least one projection which projects between an inner wall of the lumen of the drainage tube and an outer wall of the feeding tube received therein. The support means may be provided on either the stomach probe or on the jejunal probe. The invention thus also concerns a stomach probe and a jejunal probe as such.
