A tracking system for a target anatomy of a patient can include a medical device having a body (281) having a distal end (290) and at least one channel (292) formed therein, where the body is adapted for insertion through an anatomy (105) to reach a target area (430)； an accelerometer (185) connected to the body and positioned in proximity to the distal end； an imaging device (295) operably coupled with the body； and a light source (297) operably coupled with the body, where the accelerometer is in communication with a remote processor (120) for transmitting acceleration data thereto, where the imaging device is in communication with the remote processor for transmitting real-time images thereto, and where an orientation of the medical device and calibration of direction with respect to the anatomy is determined by the processor based on the acceleration data.
