(b)(4).The actual device was not returned; however, the customer returned one representative cvc kit for evaluation.The kit was opened to further inspect its components.Visual inspection of the catheter revealed no obvious defects or anomalies.The total length of the catheter body measured to be 168 mm which is within the specification of 157-177 mm per product drawing.The outer diameter of the proximal lumen measured to be 2.14 mm which is within specifications of 2.13-2.21 mm per product drawing.The inner diameter of the proximal lumen measured to be 1.4478 mm which is within specifications of 1.42-1.50 mm per product drawing.This indicates that the wall thickness measured within specifications.The outer diameter of the medial lumen measured to be 2.16 mm which is within specifications of 2.13-2.21 mm per product drawing.The inner diameter of the medial lumen measured to be 1.4732 mm which is within specifications of 1.42-1.50 mm per product drawing.This indicates that the wall thickness measured within specifications.The outer diameter of the distal lumen measured to be 2.19 mm which is within specifications of 2.13-2.21 mm per product drawing.The inner diameter of the distal lumen measured to be 1.4478 mm which is within specifications of 1.42-1.50 mm per product drawing.This indicates that the wall thickness measured within specifications.The catheter was functionally tested per the 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)." all lumens were flushed using a water-filled lab inventory syringe.All lumens flushed as expected.A manual tug test confirmed all extension lines were fully secured within the luer hubs.A device history record review was performed, and no relevant findings were identified.The instructions for use (ifu) provided with this kit warns the user, "do not apply excessive force in placing or removing catheter or guidewire.Excessive force can cause component damage or breakage.If damage is suspected or withdrawal cannot be easily accomplished, radiographic visualization should be obtained and further consultation requested.Do not secure, staple and/or suture directly to outside diameter of catheter body or extension lines to reduce risk of cutting or damaging the catheter or impeding catheter flow.Secure only at indicated stabilization locations.Open slide clamp prior to infusion through lumen to reduce risk of damage to extension line from excessive pressure." the customer report of a blocked extension line could not be confirmed by complaint investigation of the returned sample.The customer returned one representative sample, and the returned catheter passed all relevant dimensional and functional inspection.A device history record review was performed with no relevant findings.The root cause for this complaint could not be determined as the actual device was not returned, and there was no problem found with the representative sample.Teleflex will continue to monitor and trend for complaints of this nature.
