(b)(4).The customer returned one, 2-lumen, pressure-injectable (pi) picc catheter for investigation.Signs of use in the form of biological material were observed on the extension lines.It was noted that the catheter body was severed between the 3-4cm marking towards the juncture hub.The severed portion was not returned for analysis.Visual inspection revealed the distal extension line contained a hole directly adjacent to the luer hub.The remainder of the extension line was secured inside the luer hub.The catheter body length measured 1 5/8".This indicates that 14 29/32"- 15 5/32" of the catheter body was severed and not returned for analysis (per catheter product drawing).The distal extension line outer diameter measured 0.094", which is within the specifications of 0.093"-0.097" per distal extension line product drawing.The distal extension line inner diameter measured 0.057", which is within the specifications of 0.055"-0.059" per distal extension line product drawing.This indicates that the wall thickness measured within specifications.The catheter was functionally tested per the instructions for use (ifu).The ifu provided with this kit instructs the user, "flush each lumen with sterile normal saline for injection to establish patency and prime lumen(s)".When the catheter was flushed with a lab inventory water-filled syringe, water leaked out of the hole in the distal line.The proximal line flushed as expected.A manual tug test confirmed both the distal and proximal extension lines were secure to their luer hub.A device history record review was performed, and findings were identified.A non-conformance was initiated for lot numbers 13c22j0823, 13c23k0891, and 13c23f0687 to address the issue of an extension line leaking during use.The ifu provided with this kit warns the user, "do not apply excessive force in placing or removing catheter or guidewire.Excessive force can cause component damage or breakage.If damage is suspected or withdrawal cannot be easily accomplished, radiographic visualization should be obtained and further consultation requested.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 an extension line leak was confirmed through a complaint investigation of the returned sample.A hole was found in the distal extension line adjacent to the luer hub.The returned sample passed all relevant dimensional inspections.The type of damage observed is consistent with a manufacturing issue in the picc lines, therefore, the probable root cause is manufacturing related.A non-conformance has been initiated to further investigate this issue.Teleflex will continue to monitor and trend on complaints of this nature.
