Abstract
A catheter system includes a elongate catheter having a longitudinal slit for facilitating removal of a rigid stylet after manipulating the catheter to a desired position. In one embodiment, the stylet is contained within the catheter prior to use. The stylet is removed by bending the catheter such that a proximal portion of the stylet protrudes from the slit to allow a surgeon to grasp and remove the stylet from the catheter. In an exemplary embodiment, the catheter system includes a ventricular catheter for draining fluid from a patient's brain ventricle.
