(b)(4).The customer returned one, 4-lumen catheter for analysis.Signs of use were observed.Visual analysis revealed the catheter body was severed.Additional information from the customer does not report a severing of the catheter body which suggests the catheter was intentionally cut after the defect was observed.No signs of a blockage were observed within the lumens at the distal end.No signs of kinking were observed on either of the four extension lines.The catheter body was severed 82 mm from the juncture hub.The outer diameter of the 12.7 cm medial extension line measured 2.21 mm, which is within the specification limits of 2.13-2.21 mm per the medial extension line extrusion drawing.The inner diameter of the 12.7 cm medial extension line measured 1.40 mm, which is within the specification limits of 1.40-1.48 mm per the medial extension line extrusion drawing.The outer diameter of the 14 cm medial extension line measured 2.21 mm, which is within the specification limits of 2.13-2.21 mm per the medial extension line extrusion drawing.The inner diameter of the 14 cm medial extension line measured 1.42 mm, which is within the specification limits of 1.42-1.50 mm per the medial extension line extrusion drawing.The outer diameter of the distal extension line measured 2.21 mm, which is within the specification limits of 2.13-2.21 mm per the distal extension line extrusion drawing.The inner diameter of the distal extension line measured 1.42 mm, which is within the specification limits of 1.42-1.50 mm per the distal extension line extrusion drawing.The outer diameter of the proximal extension line measured 2.15 mm, which is within the specification limits of 2.13-2.21 mm per the proximal extension line extrusion drawing.The inner diameter of the proximal extension line measured 1.42 mm, which is within the specification limits of 1.42-1.50 mm per the proximal extension line extrusion drawing.The catheter was functionally tested per the product instructions-for-use (ifu).The ifu provided with this kit instructs the user, "flush each lumen with sterile normal saline for injection to establish patency and prime lumen(s)." a lab inventory filled with water was used to flush each extension line.No signs of a blockage were observed when each lumen was flushed.A manual tug test confirmed that the extension lines were secure within their respective luer hubs.Additional information from the customer was reviewed as a part of this complaint investigation.The customer stated , "the problem was solved by turning the line upside down to remove the twisted part." this suggests the extension line became twisted/kinked during use and was able to return to patency when the customer repositioned the extension line.However, it is unknown which extension line became twisted, and whether unintentional catheter manipulation or patient movement may have contributed to the obstruction in the extension line.The customer did not provide a lot number; therefore, a device history record review was performed based upon a lot number taken from the sales history data of the customer.No relevant findings were identified.The ifu provided with this kit informs the user , "minimize catheter manipulation throughout procedure to maintain proper catheter tip position.Do not alter the catheter, guidewire or any other kit/set component during insertion, use or removal." the customer report of an extension line kink was not confirmed through investigation of the returned sample.Visual and functional inspections of the catheter did not reveal any defects or anomalies with either of the four extension lines.The catheter met all relevant dimensional and functional requirements.Based on the customer report and the returned sample, the root cause cannot be determined as it is unknown which extension line became twisted, and whether unintentional catheter manipulation or patient movement may have contributed to the obstruction in the extension line.Teleflex will continue to monitor and trend on reports of this nature.
