Low profile adaptor for use with a medical catheter, such as a gastrostomy feeding tube. In a preferred embodiment, the adaptor comprises a body having a lower portion and an upper portion. A first channel is provided in the lower portion, and a second channel is provided in the upper portion, the first and second channels being perpendicular to and in fluid communication with one another. A generally cylindrical stem is coaxially positioned within the second channel, the stem being rotatably mounted about its longitudinal axis. The stem is hollow and has an open front end, a closed rear end and a hole in its side wall, the hole being rotatably alignable with the first channel. To facilitate rotational alignment of the hole with the first channel, a stop is formed on the exterior of the stem, the stop being engageable with a surface 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. The proximal end of the gastrostomy feeding tube is inserted over the lower portion of the body and is secured thereto with a nut.
