Qn#(b)(4).The customer returned one clamp catheter and clamp fastener for investigation.Visual examination of the clamp catheter and clamp fastener did not reveal any defects or anomalies.Visual inspection of the catheter could not be performed as it was not returned for investigation.The inner diameter of the clamp catheter measured to be 0.092" (2.336 mm) which is within specifications of 2.240-2.340 mm per product drawing.The inner diameter of the clamp fastener measured to be 0.178" (4.52 mm) which is within specifications of 4.32-4.57 mm per product drawing.Functional inspection was performed per the product instructions-for-use.The ifu states the following: "secure catheter to patient.Use triangular juncture hub with integral suture ring and side wings as primary suture site.In kits where provided, the catheter clamp and fastener should be utilized as a secondary suture site as necessary." the returned clamp catheter and clamp fastener were attached to a lab inventory catheter.The box clamp assembly was held stationary, and the catheter was pulled in both directions.The box clamp did not shift position on the catheter body and the catheter was not able to migrate.A device history record review was performed, and no relevant findings were identified.The ifu provided with this kit instructs the user, "secure catheter to patient.Use triangular juncture hub with integral suture ring and side wings as primary suture site.In kits where provided , the catheter clamp and fastener should be utilized as a secondary suture site as necessary." the customer report of a catheter migration could not be confirmed by complaint investigation of the returned sample.No defects or anomalies were observed with the returned catheter clamp and catheter fastener.A device history record review was performed with no relevant findings.Upon functional testing, the box clamp assembly did not shift position on the lab inventory catheter body and the catheter was not able to migrate.Additionally, the primary suture location for the catheter is the juncture hub using the triangular wings.Since the catheter was not returned, a full complaint verification could not be performed.Additionally, it could not be determined if the box clamp was used as the primary or secondary suture site.Therefore, the probable root cause could not be determined based on the sample received, the information available, and without the actual catheter to evaluate.Teleflex will continue to monitor and trend for complaints of this nature.
