1. A method for implanting an elongate medical device into a brain of a patient, the method comprising:
obtaining trajectory path information regarding a path entry point, a target location, a trajectory path and 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 the 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 support member configured to be secured to the cranium and surround the burr hole in a close proximity;
adjusting a translational movement of the IC assembly by actuating an X-Y slider table of the trajectory guiding apparatus to align the IC assembly to the path entry point in the burr hole, the X-Y slider table being disposed at a horizontal support member extending from a top of a vertical support;
adjusting a pivotal rotational movement of the IC assembly by actuating at least one of a first gimbal drive or a second gimbal drive of the trajectory guiding apparatus to align an axial angle of the IC assembly with the entry angle, the first gimbal drive and the second gimbal drive being disposed at a stage portion pivotably coupled to a bottom of the vertical support; and
advancing the elongate medical device along the trajectory path using a drive assembly associated with the IC assembly until the target location within the brain is reached, wherein the drive assembly is operable to independently actuate the first gimbal drive and the second gimbal drive to maintain alignment of the elongate medical device with the trajectory path.
