An intracranial pressure monitoring and drainage catheter having two tubes that are joined into a single tube at the catheter body distal end, each tube having a separate lumen. One tube is severed at a location proximal to the catheter body distal end and has an internal connector that may be removed from one severed end to introduce a stylet into the lumen. The stylet results in increased rigidity of the catheter body distal end to assist in placing the catheter in the patient. The wall of the distal end of the catheter has drainage apertures formed in communication with the lumen in which the stylet is placed. Reconnecting the internal connector after removal of the stylet provides a fluid path from the distal end of the catheter body to the proximal end of the catheter for drainage of fluid from the patient. A sensor may be placed in the other lumen for sensing a physical parameter of the patient, such as pressure or temperature or both.
