(b)(4).The customer returned a 2-l cvc catheter for evaluation.Signs of use in the form of sutures were found on the catheter body.Visual inspection of the catheter confirmed the distal extension line contained a cut parallel with the line near the luer hub.The cut was smooth, consistent with a sharp instrument such as a scalpel or scissors contacting the extension line.The total length of the catheter body measured 215 mm, which is within specifications of 207-227 mm per catheter graphic.The distal extension line was cut 2-4 mm, from the luer hub.The outer diameter of the distal extension line measured 2.426 mm, which is within specifications of 2.39-2.49 mm per distal extension line extrusion graphic.The inner diameter of the medial extension line measured 1.6764 mm , which is within specifications of 1.65-1.75 mm per medial extension line extrusion graphic.The catheter was functionally tested per the instructions for use (ifu).The ifu provided with this kit states, "flush each lumen with sterile normal saline for injection to establish patency and prime lumen(s)." when the distal line was flushed, water leaked out of the cut near the luer hub.The proximal line flushed as expected.A manual tug test confirmed the proximal and distal luer hubs were secure to their extension lines.A device history record review was performed, and no relevant findings were identified.The ifu provided with this kit warns the user, "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." the complaint of an extension line leak during use was confirmed by investigation of the returned sample.The distal extension line had a cut parallel with the line near the luer hub.The cut was smooth, consistent with a sharp object contacting the extension line.A device history record review was performed, and no relevant findings were identified.Based on the customer description and the sample returned, unintentional use error likely caused or contributed to this event.Teleflex will continue to monitor and trend on complaints of this nature.
