(b)(4).The customer returned one, single-lumen picc and connector tubing for analysis.Signs of use were observed on the catheter body.Visual analysis revealed that the extension line was severed adjacent to the juncture hub.Microscopic examination confirmed the damage and revealed that the edges are smooth and uniform, which is damage consistent with damage resulting from contact with a sharp instrument (i.E.Scissors, scalpel, etc).The point of separation measured 53mm from the luer hub and 1mm from the juncture hub.The distal extension line outer diameter measured 0.0935", which is within the specification limits of 0.0930"-0.0970" per the distal extension line extrusion product drawing.The distal extension line inner diameter at the point of separation measured 0.056", which is within the specification limits 0.055"-0.059" per the distal extension line extrusion product drawing.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 separated extension line was confirmed through complaint investigation.Visual analysis revealed that extension line was severed adjacent to the juncture hub.The appearance of the separation is consistent with damage resulting from contact with a sharp object (i.E.Scissors, scalpel, etc.).Despite the damage, all relevant dimensional requirements were met, and a device history record review did not reveal any relevant findings to suggest a manufacturing related issue.Based on the customer report that the defect occurred during use and the appearance of the damage, unintentional use error likely caused or contributed to this event.Teleflex will continue to monitor and trend for reports of this nature.
