(b)(4).The customer returned one 3-l cvc and the product lidstock for analysis.Signs of use in the form of dried biological material were observed on the catheter.Visual inspection of the catheter revealed no obvious defects or anomalies.The catheter body length measured 620mm, which is within the specifications of 604-624mm per product drawing.The proximal extension line outer diameter measured 2.156mm, which is within the specifications of 2.13-2.21mm per product drawing.The proximal extension line inner diameter measured 1.4478mm which is within the specifications of 1.42-1.50mm per product drawing.Functional inspection of the catheter was performed per the instructions for use (ifu) provided with the kit which states, "flush each lumen with sterile normal saline for injection to establish patency and prime lumen(s)." all extension lines were flushed using a lab inventory 10ml syringe to test for leaks or blockages.All extension lines flushed normally.No leaks or blockages were observed.The distal tip of the catheter was placed into a beaker with water, and water was aspirated out of the proximal extension line with a 10ml lab inventory syringe.No blockages were observed.A manual tug test confirmed all extension lines were secured to their respective luer hubs.A device history record review was performed with no relevant findings.The ifu provided with this kit warns the user, "caution: minimize catheter manipulation throughout
procedure to maintain proper catheter tip position." the customer report of a blocked catheter could not be confirmed through complaint investigation of the returned sample.Functional inspection revealed all extension lines flushed normally.The catheter met all relevant dimensional requirements, and a device history record review was performed with no relevant findings.Based on these circumstances, no problem was found with the returned sample.Teleflex will continue to monitor and trend for complaints of this nature.
