Additional Manufacturer Narrative

A PRODUCT INVESTIGATION WAS PERFORMED. A VISUAL INSPECTION UNDER 5X MAGNIFICATION, DEVICE HISTORY RECORD (DHR) REVIEW, AND DRAWING REVIEW WERE PERFORMED AS PART OF THIS INVESTIGATION. NO PRODUCT DESIGN ISSUES OR DISCREPANCIES WERE OBSERVED. THIS COMPLAINT IS CONFIRMED. VISUAL INSPECTION AT CUSTOMER QUALITY (CQ) CONFIRMED THE COMPLAINT CONDITION. THE SLIGHTLY OBLIQUE FRACTURE OCCURRED JUST PROXIMAL TO THE DISTAL THREADED TIP. THE THREADED TIP FRAGMENT WAS NOT RETURNED. WHETHER THIS COMPLAINT CAN BE REPLICATED AT CUSTOMER QUALITY (CQ) IS NOT APPLICABLE FOR THIS COMPLAINT CONDITION AS THE RETURNED DEVICE IS ALREADY BROKEN. NO NEW MALFUNCTIONS WERE IDENTIFIED AS A RESULT OF THE INVESTIGATION. THE MATERIAL AND RELEVANT MATERIAL PROPERTIES WERE DETERMINED TO BE CONFORMING AT THE TIME OF MANUFACTURE BASED ON REVIEW OF THE DHR. RELEVANT DRAWINGS WERE REVIEWED DURING THIS INVESTIGATION. NO PRODUCT DESIGN ISSUES OR DISCREPANCIES WERE OBSERVED. THE INSIDE DIAMETER (CANNULATION) AND THE OUTSIDE DIAMETER NEAR LOCATION OF BREAKAGE WAS MEASURED AT CQ AND FOUND TO BE WITHIN SPECIFICATION PER RELEVANT DRAWING. UNABLE TO DETERMINE A DEFINITIVE ROOT CAUSE. THE SLIGHTLY OBLIQUE FRACTURE DOES SUGGEST AN OFF-AXIS FORCE WAS APPLIED THEREBY CAUSING THE BREAKAGE. NO NEW, UNIQUE OR DIFFERENT PATIENT HARMS WERE IDENTIFIED AS A RESULT OF THIS EVALUATION. THE RETURNED PART WAS DETERMINED TO BE SUITABLE FOR THE INTENDED USE WHEN EMPLOYED AND MAINTAINED AS RECOMMENDED. DEVICE WAS USED FOR TREATMENT, NOT DIAGNOSIS. IF INFORMATION IS OBTAINED THAT WAS NOT AVAILABLE FOR THE INITIAL MEDWATCH, A FOLLOW-UP MEDWATCH WILL BE FILED AS APPROPRIATE.
