Qn#(b)(4).The customer returned one 2-l catheter and box clamp assembly for analysis.Signs of use in the form of biological material were observed on the catheter body.Visual analysis revealed that the box clamp was returned attached to the catheter body; however, it was located over the distal end.Visual analysis of the catheter, clamp fastener, and clamp catheter did not reveal any defects or anomalies.There is no evidence to suggest that the catheter suture wings (on juncture hub) were ever secured with sutures.The outer diameter of the returned catheter body measured to be 2.46mm, which is within specifications of 2.36mm-2.46mm per product drawing.The inner diameter of the clamp fastener measured 4.4704mm, which is within the specification limits of 4.32mm - 4.57mm pe r the clamp fastener product drawing.The catheter clamp and fastener were attached to the returned catheter body.The box clamp assembly was held stationary, and the catheter was pulled in both directions.Little to no movement was identified.The suture wings of the juncture hubs were then held stationary, and the catheter was pulled in both directions.No movement was identified.Performed per ifu statement , "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".A device history record review was performed, and no relevant findings were identified.The ifu provided with the kit informs 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 did not state whether the catheter juncture hub was used as the primary securement site.The customer report of a catheter migration could not be confirmed by complaint investigation of the returned sample.Little to no movement of the catheter was observed when secured by only the box clamp.The catheter also passed testing when secured by the juncture hub suture wings.The primary suture location for this catheter is the juncture hub using the triangular wings.It could not be determined if the box clamp was used as the primary or secondary suture site; therefore, the probable cause could not be determined.Teleflex will continue to monitor and trend for complaints of this nature.
