Qn# (b)(4).A device history record review was performed on the stimucath catheter with no relevant findings.The customer reported the catheter the catheter tip kinks and infusion is impossible.The customer retuned one adaptor catheter and one stimucath catheter.The components were received connected together.Visual examination of the returned adaptor catheter revealed the adapter appears typical with no observed defects or anomalies.Visual examination of the returned catheter revealed the tip at the distal end is slightly bent as compared to a lab inventory.No other defects or anomalies were observed.A manual flow test was performed using the returned catheter and adapter catheter.A 20ml lab inventory syringe was connected to the returned components.Using hand pressure, the water was injected.Water could be seen immediately exiting the distal end of the catheter.No blockages were found.Also, a catheter stylet was fully inserted into the catheter with no resistance met.The reported complaint of the catheter being kinked and medication not injecting through could not be confirmed based on the sample received.A device other remarks: history record review was performed on the stimucath catheter with no evidence to suggest a manufacturing related issue.Although the returned distal tip was slightly bent compared to a lab inventory catheter, the returned catheter passed a functional flow test and a stylet could be fully inserted with no resistance met.Therefore, based on this, no functional issues found with the returned sample.
