Low profile adaptor (11) for use with a medical catheter, such as a gastrostomy feeding tube. In a preferred embodiment, the adaptor comprises a body (13) having a lower portion (15) and an upper portion. A first channel (25) is provided in the lower portion, and a second channel (37,39,41) is provided in the upper portion, the first and second channels being per- pendicular to and in fluid communication with one an-other. A generally cylindrical stem (71) is coaxially posi-tioned within the second channel, th e stem being rotata-bly mounted about its longitudinal axis. The stem is hollo w and has an open front end (73), a closed rear end (75) and a hole (85) in it s side wall, the hole being rotatably alignable with the first channel. To facilitate rotational align-ment of the hole with the first channel, a stop is formed on the exterior of the stem, the stop being engageable with a surface (59) positioned within the second channel. The front end of the stem is recessed relative to the front end of the second channel to prevent unwanted rotation of the stem. Rotation of the stem from a closed position to an open position is achieved by screwing a syringe onto the front end of the stem. T he proximal end of the gas-trostomy feeding tube is inserted over the lower portion of the body and is secured thereto with a nut (91).
