1. A method of inserting a catheter into a patient, comprising:

  • registering a stereotactic system to the patient;

    inserting the catheter having a tip protection device disposed over a distal tip thereof into a working channel of the stereotactic system until a depth stop on the tip protection device prevents further insertion, the tip protection device comprising an elongate body having a central lumen extending longitudinally therethrough configured to slidably receive the catheter, the tip protection device further including a locking mechanism comprising a set screw configured to intersect the central lumen, wherein the locking mechanism of the tip protection device is engaged with a portion of the catheter in the central lumen during insertion to hold the catheter in a fixed longitudinal position with respect to the tip protection device and, thereby, to prevent the catheter from advancing longitudinally any of distally and proximally in the tip protection device;

    releasing the locking mechanism of the tip protection and advancing the catheter distally into the patient; and

    engaging a locking mechanism of the stereotactic system with the tip protection device by tightening a set screw of the stereotactic system such that the set screw contacts an outer surface of the body of the tip protection device while the catheter is located within the central lumen of the tip protection device, thereby engaging the tip protection device onto the catheter to maintain a fixed longitudinal position between the catheter and the stereotactic system.
