(b)(4).The customer provided one image showing the kit sticker label.The customer also returned one single-lumen, pressure-injectable (pi) picc for analysis.Signs of use in the form of biological material were observed inside the catheter.After failing functional testing, a small hole was observed on the extension line extrusion.Microscopic examination confirmed the damage and revealed that the edges were smooth and uniform.The appearance of the hole is consistent with contact with a sharp object (i.E.Needle, scalpel, sutures, etc.).The extension line outer diameter measured 0.095", which is within the specification limits of 0.093"-0.097" per the extension line extrusion product drawing.The extension line inner diameter measured 0.057", which is within the specification limits of 0.055"-0.059" per the extension line extrusion product drawing.A lab inventory syringe filled with water was attached to the extension line and flushed.Water was observed leaking from the hole on the extension line.Performed per ifu statement, "flush each lumen with sterile normal saline for injection to establish patency and prime lumen(s)".A device history record review was performed, and no relevant findings were identified.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 analysis of the returned sample.Visual and functional analysis revealed a leak from a cut on the extension line extrusion.Microscopic examination confirmed the damage and revealed that the edges were smooth and uniform.The appearance of the hole is consistent with contact with a sharp object (i.E.Needle, scalpel, sutures, etc.).Despite the damage, the sample met all relevant dimensional requirements, and a device history record review did not reveal any relevant findings.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.
