(b)(4).The device history review did not show issues related to the complaint.The visual examination of the sample showed that the catheter was broken in two parts.The sample was aligned and the total length was measured and met the specifications for this product.Both the shaft and the funnel were examined using the dino-lite to analyze the damaged area and torn edges.It was observed that the torn edges were jagged and there was excessive material at one side indicating that there is some external force applied at the joint area causing the catheter to break.The funnel portion revealed some cutting edges suggesting that the tube was once well attached to the funnel.No other nicks, abrasion, marks, or scratches were observed on the embedded shaft that could have likely caused the breakage.Other remarks: the manufacturer performed positive released tests at the injection molding process with representative samples using weight load testing to test the bonding strength between the funnel and tube prior to release.Based on the investigations no problem was found within the product which could have contributed from manufacturing processes.Therefore this complaint could not be confirmed.The root cause is unknown.The manufacturer will continue to monitor and trend related events.
