CORRECTIVE AND PREVENTIVE ACTIONS: THERE WAS NO QUALITY AND PERFORMANCE ISSUES OR MALFUNCTION OF NORAS OR HEAD HOLDER.

Description of Event or Problem

AS INFORMED BY THE HOSPITAL, ONE OF THE TWO PLANNED INTRACRANIAL BIOPSIES FOR THE SAME PATIENT, SUPPORTED BY THE BRAINLAB NAVIGATION SYSTEM, WAS UNSUCCESSFUL AT THE FIRST ATTEMPT. THE USER VERIFIED WITH AN MRI SCAN THAT THE ACTUAL APPLIED TRAJECTORY DIFFERED FROM THE PLANNED, INTENDED TRAJECTORY FOR THE UNSUCCESSFUL BIOPSY ATTEMPT. THE INITIALLY UNSUCCESSFUL BIOPSY WAS REPEATED DIRECTLY AFTER THE RE-SCAN OF THE PATIENT AND COMPLETED SUCCESSFULLY.
