Method - the broken device was discarded by the end user.No sterile samples have been received to date.Results - no samples were returned for testing / review.There is no available stock of lot aabl227.Relevant portions of the device history record were reviewed.The product from the finished good lot and all components met current usp and surgical specialties mexico requirements throughout the incoming, manufacturing, in-process and final inspection processes.Without receiving the actual re-sterilized device for review, sterile samples for ductility testing or receiving detailed information regarding the pre-operative preparations of the needle device, procedure or the surgeon's technique, a definitive root cause for the needle breaking during the procedure cannot be determined with certainty.

Ten (10) sterile samples were returned and visually examined under 20 % magnification and ductility tested per the specified requirements for this size/type needle component.All results were acceptable per the 45deg.Bend test and no defects were noted during the visual review.Without receiving specifics regarding the pre-operative preparation of the device, type or size needle driver utilized in conjunction with the device, or location on the needle where it was grasped with the driver, a definitive root cause for the needle breaking during the procedure cannot be determined at this time.The bending or fracturing of a needle can occur when needles are gripped with a needle holder/forceps at the swaged area and/or near the tip of the device.The stress at the gripped area may exceed the maximum stress of the material resulting in bending and/or failure (broken needle).The stress on the attachment section is greatly reduced when the needle is held in an area one-third (1/3) to one-half (1/2) of the distance from the swaged end to the point as indicated in the ifu for this product.
