A multifunctional catheter probe for carrying out intracorporal measurements, including a multiluminal flexible tubing divided into sections and joined together by coupling pieces and forming a multifunctional catheter probe. Each coupling piece has a central body with a central feed lumen lead-through and measurement lumen lead-throughs which are arranged around. The coupling is accomplished with suitable attachment nipples to the lumens of the flexible tube sections. A measurement lumen passage closed in the passage has a radial opening in or on which different measuring devices for the manometric or electro-sensory are attached.
