Without reviewing the actual sample, an exact root cause for the non-conformance reported cannot be determined at this time.A possible cause could be bending, fracturing, breaking 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.The needle itself is from supplied by an outside supplier.A review of the device history records for the finished good lot, did not identify any quality issues during the incoming, manufacturing, in-process or final inspection processes.There have been no lots released for distribution which failed to meet any of the product specifications or current acceptance criteria.
