Qn#(b)(4).The customer returned one single-lumen catheter for evaluation.After the sample failed functional testing, the extension line was microscopically examined.Significant signs of adhesive material were found on the lumen.A small slit was also detected, causing the leak.The slit was smooth and straight, indicating contact with a sharp object (scissors, scalpel, needle, etc.) caused the damage.The total length of the returned catheter measured to be 207 mm which is within specifications of 200-212.8 mm per product drawing.The distal lumen contained one slit 3 mm from proximal end of the juncture hub.The inner diameter of the returned lumen measured to be 0.058" which is within specifications of 0.055-0.059" per product drawing.The outer diameter of the returned lumen measured to be 0.087" which is within specifications of 0.084-0.088" per product drawing.This indicates that the wall thickness measured within specifications.The catheter was flushed using a water-filled lab inventory syringe.Water leaked from a small slit in the lumen.A device history record review was performed with no relevant findings.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 customer report of an extension line leak was confirmed by complaint investigation of the returned sample.The distal lumen contained one small slit with damage consistent with coming in contact with a sharp object.The sample passed all relevant dimensional inspection and a device history record review was performed with no relevant findings.Based on the condition of the sample received and the report that the catheter was placed for 2 weeks prior to defect, unintentional user error caused or contributed to this event.Teleflex will continue to monitor and trend for complaints of this nature.
