(b)(4).Method: actual device was received for evaluation and investigation.A visual inspection and tensile strength test were conducted.A review of the device history record (dhr) was performed.Results: a visual inspection found that two catheters were returned with the pump.Only one catheter will be tested because the other catheter had no issues when removing from the patient.The catheter was returned not fully intact, missing the black catheter tip.Multiple kinks observed at the infusion segment where the breakage is.The diameter of the kinked part was measured to be 0.025¿.The non-kinked part was measured to be 0.043¿.The catheter was examined under a microscope magnified at 1.6x, no signs of brittleness were observed.Tensile strength was performed on the catheter.The passing rate for the test is >2.8(lbf) at the infusion segment and >4.00 (lbf) for the mid-body segment.The result for the catheter mid-body segment is 9.04(lbf).The result for the infusion segment is 4.55(lbf).The catheter met specifications during the tensile test and no additional testing was performed.Conclusion: the investigation summary concludes that the catheter was received not fully intact, missing the black tip.Evidence revealed that stretching was observed where the breakage occurred.Tensile strength was performed on the mid-body segment and met specifications.The dhr was reviewed for the lot number of the manufactured unit.There were no reworks, special conditions, or related nonconformance reports (ncrs) for this lot.It was reported that resistance was met when removing the catheter.The instructions for use (ifu) specifies, "if resistance is encountered or catheter stretches, stop.Continued pulling could break the catheter.¿ it¿s advisable to cover the site with warm compresses, and wait 30 to 60 minutes, and try again.The patient¿s body movements may relieve the catheter to allow easier removal.¿ for additional information refer to the technical bulletin: tips for preventing in-situ catheter breakage with the on-q* system.¿ do not cut or forcefully remove catheter.¿ after removal, check distal end of catheter for black marking to ensure entire catheter was removed (figure 12 on page 2)." an instructions for use (ifu) ((b)(4)) and a technical bulletin, preventing catheter breakage, were sent to the customer.Should additional information pertinent to this case be received, a follow up report will be submitted.Information from this incident has been included in our product complaint and mdr trend reporting systems.Trend information is used to identify the need for additional investigations.
