Qn#(b)(4).The customer returned one, 3-lumen cvc for analysis.Signs of use in the form of biological material were observed inside the catheter body.Visual analysis revealed that the proximal extension line contained a hole around the middle of the extrusion.Microscopic examination confirmed the damage and revealed that the edges were smooth and uniform.The appearance of the damage is consistent with contact with a sharp instrument (i.E.Scissors, scalpel, etc).The hole on the proximal line measured 115mm from the luer hub (white).The proximal line outer diameter measured 0.085", which is within the specification limits of 0.084"-0.088" per the proximal extension line extrusion product drawing.The proximal extension line inner diameter measured 0.056", which is within the specification limits of 0.055"-0.059" per the proximal extension line extrusion product drawing.A lab inventory syringe filled with water was attached to all three extension lines and flushed.When flushing the proximal line, water was observed leaking from the hole.No leaks were detected when flushing the medial or distal lines.Performed per ifu statement, "flush lumen(s) to completely clear blood from catheter".The ifu provided with the kit informs 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 report of a leaking extension line was confirmed through complaint investigation.Visual and functional analysis revealed a hole on the proximal extension line.The edges of this hole appear smooth, uniform and consistent with damage resulting from contact with a sharp instrument (i.E.Scissors, scalpel, etc.).Despite the damage, the sample met all relevant dimensional requirements.Based on the customer report and the sample received, unintentional use error likely caused or contributed to this event.Teleflex will continue to monitor and trend for reports of this nature.
