Visual and dimensional analysis was performed on the returned device.The reported difficulty removing the catheter was unable to be confirmed.Lot history record (lhr) and corrective and preventive actions (capa) reviews were performed and revealed no indication of a product quality issue.Additionally, a query of the complaint handling database for the reported lot revealed there is no indication of a lot specific issue.The investigation determined that the difficulty removing the catheter was related to operational context.The distal end of the guidewire exit notch was noted to be stretched, which suggests that either positioning or withdrawal difficulty was encountered during use but cannot be directly attributed as the cause for the difficulty to remove.There were no other damages nor anomalies to the catheter which could be directly attributed to reported difficulty to remove.It is likely that the difficulty removing the catheter was caused by patient anatomical conditions, contamination on guidewire, guidewire damage, or the use techniques employed.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
