(b)(4).The customer returned one, 2-lumen picc catheter for analysis.Signs of use in the form of excess biological material were observed on and within the sample.Visual analysis revealed excess biological material on the proximal lumen skive hole.The slide clamps were activated upon return.The clamp catheter/box clamp assembly was attached to the catheter around the 44 cm mark.During functional testing, a slight blockage was observed in the white proximal lumen and biological material was observed exiting the proximal lumen after several flushes with water.The customer description stated the catheter was in use in the patient for twelve (12) days prior to the blockage being detected.The catheter body length from the juncture hub to the distal tip measured 19 7/8", which is within the specification limits of 19 1/2" - 20" per catheter product drawing.The outer diameter of the catheter body measured 0.0710", which is within the specification limits of 0.0705" - 0.0710" per catheter extrusion product drawing.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)." all slide clamps were deactivated.Prior to removal of the clamp catheter/box clamp assembly, a lab inventory syringe was used to flush each extension line.No blockage was observed when the pink distal lumen was flushed; however, a partial blockage was confirmed within the white proximal lumen.Biological material was observed exiting the proximal skive hole of the catheter and the blockage was cleared after several flushes with water.The clamp catheter/box clamp assembly was removed, and both lumens still flushed as intended.A lab inventory 0.018" guide wire (measured 0.018") was threaded through the catheter.The guide wire advanced through the catheter with little to no resistance.A device history record review was performed, and no relevant findings were identified.He ifu provided with this kit warns the user, "flush lumen(s) to completely clear blood from catheter.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 customer report of a blocked catheter was confirmed through complaint investigation of the returned sample.Functional testing of the returned catheter revealed a partial blockage within the white proximal lumen due to excess biological material.The blockage was cleared after several flushes with water, and the catheter met all relevant dimensional and functional requirements.It was noted that the customer stated the catheter was functionally in use for twelve (12) days prior to the blockage being detected.A device history record review was performed, and no relevant findings were identified.Based on the customer report and the sample received, unintentional use error likely caused or contributed to the reported event.Teleflex will continue to monitor and trend on reports of this nature.
