Qn# (b)(4).The report of a blocked catheter was not able to be confirmed as part of this complaint investigation.The customer returned one, opened cvc kit containing a 3-lumen catheter.Signs-of-use in the form of biological material were observed.Visual analysis did not reveal any obvious defect or anomalies.The catheter body length from the juncture hub to the distal tip measured 218mm via calibrated ruler, which is within the specification limits of 207mm-227mm per the catheter product drawing.The catheter body outer diameter measured 0.09665" via calibrated micrometer, which is within the specification limits of 0.094"-0.098" per the catheter extrusion product drawing.Functional inspection was performed per ifu statement, "flush lumen(s) to completely clear blood from catheter", where a lab inventory syringe filled with water was attached to all three extension lines and flushed.No blockages were encountered as the water was able to exit through the respective skive holes.Additionally, a lab inventory 0.032" guide wire was also inserted through the catheter body per ifu statement, "thread tip of catheter over guidewire.Sufficient guidewire length must remain exposed at hub end of catheter to maintain a firm grip on guidewire".Little to no resistance was encountered as the guide wire passed completely through the assembly.The catheter product drawing and the catheter extrusion product drawing were reviewed as part of this complaint investigation.The ifu provided with the kit informs the user, "open slide clamp prior to infusion through lumen to reduce risk of damage to extension line from excessive pressure".The ifu also states, "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".A device history record review was performed, and no relevant findings were identified.The report of a blocked catheter was not able to be confirmed as part of this complaint investigation.Based on the customer report and the sample received, no problem was found with the returned device.Teleflex will continue to monitor and trend for reports of this nature.
