1. A method for implanting an elongate medical device into a patient's brain, the method comprising:
obtaining trajectory path information regarding an entry angle with respect to implanting the elongate medical device through a cranium of the patient, the elongate medical device configured to provide a particular therapy;
creating a burr hole in the cranium around a path entry point;
attaching a trajectory guiding apparatus including an instrumentation column (IC) assembly that contains the elongate medical device, the trajectory guiding apparatus having a base plate configured to be secured to the cranium and surround the burr hole;
adjusting a translational movement by actuating a bottom stage slider (BSS) table of the trajectory guiding apparatus to align the IC assembly to the path entry point in the burr hole, wherein the BSS table is configured to translate along a first direction within a first plane;
adjusting a rotational movement by actuating a top stage slider (TSS) table of the trajectory guiding apparatus to align an axial angle of the IC assembly with the entry angle, wherein the TSS table is configured to translate along a second direction within a second plane that is different from, and parallel to, the first plane; and
advancing the elongate medical device using a drive assembly associated with the IC assembly until a target location is reached.
