(b)(4).The actual device involved in the reported incident was not returned for evaluation.However, the facility did send photos of the involved catheter.Based on the photos, the catheter appeared to be fractured / sheared near the tip end, with the inner coil unwound and stretched out at the area of the break.However, no specific conclusions can be drawn from the photos.It was indicated in the event summary that the catheter was removed through the needle.Incidents of this nature can occur if the catheter is withdrawn or partially withdrawn through the needle, thereby shearing the catheter.Per the instructions for use (ifu) for the reported product catalog number, "do not withdraw catheter through needle because of the possible danger of shearing." review of the discrepancy management system database performed for the reported lot number did not reveal any abnormalities or nonconformances of this nature.No adverse quality trends of this nature were identified during the complaint review process for the reported catalog number or catheter material number.There were no other reports of this nature against the reported lot number.If additional pertinent information becomes available, a follow-up report will be filed.
