(b)(4).The customer returned one, 2-lumen cvc, a stopcock, and a lidstock for analysis.Signs of use in the form of biological material were observed inside the catheter body.After failing functional testing (see below), visual analysis revealed a small hole in the catheter body around the 15cm marking.Microscopic examination confirmed the damage and revealed that the appearance of the hole is consistent with damage due to contact a sharp instrument (i.E.Scalpel, scissors , etc.).The catheter body total length measured 217mm, which is within the specification of 210-227mm per catheter product drawing.The catheter body outer diameter measured 2.422mm, which is within the specification of 2.36mm-2.46mm per catheter extrusion product drawing.The cut on the catheter body measured 73 mm from the juncture hub.Functional inspection was performed on the returned catheter to recreate the product's intended use.The ifu provided with this kit states: "flush each lumen with sterile saline solution, to establish patency and prime lumen(s)".With the distal end of the catheter body occluded, both extension lines were flushed with a lab inventory arrow raulerson syringe (ars).When flushing the distal extension line, water was observed leaking at approximately the 15cm marking.The proximal extension line flushed as expected.A manual tug test confirmed the extension lines were fully secured within their respective hubs.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 complaint of a catheter leaking was confirmed by a complaint investigation of the returned sample.Functional testing revealed a cut in the catheter body near 15cm marking.The cut was smooth, consistent with a sharp object contacting the catheter body.A device history record review was performed, and no relevant findings were found.Based on the sample returned, and the customer description that the damage was observed during use, unintentional use error (contact with sharps) , likely caused or contributed to this issue.Teleflex will continue to monitor and trend on complaints of this nature.
