Our product evaluation lab received one model 12tlw803f catheter with attached bd 1.0 ml syringe.A guidewire was inserted into thru-lumen from hub to 34.5 cm proximal from the tip.The gate valve was able to be opened and closed without resistance.No visible damage was observed from the gate valve.The balloon was found to be ruptured.After cutting distal windings, the ruptured edges did not appear to match up.Per the ifu, balloon rupture and catheter separation as a result of excessive pull force applied to remove adherent material are the most frequent causes of reported failures.To minimize the risk of vessel damage, balloon rupture, or tip detachment, do not exceed the maximum recommended inflation volume and pull force for each size catheter.As received, the thru-lumen was occluded with blood at 5 cm proximal from tip.To remove the blood, the catheter was cut at 20 cm proximal from the tip.With hot water and lab stylet wire, the blood was removed.Thru-lumen of the catheter was tested for the patency with lab 0.018 inch and returned guidewire and the guidewires could pass through tip to proximal or proximal to tip with both catheter parts.No other visible damage or inconsistency was observed from catheter body and windings.A device history record review was completed and documented that the device met all specifications upon distribution.The customer report of the gate valve became unable to be opened and the guidewire did not pass through the catheter, were unable to be confirmed.An engineering evaluation was completed, and product risk assessment was generated earlier which addressed the balloon with fragmentation failures for thru-lumen products.No corrective action was required.Complaint histories for all reported events are reviewed against trending control limits, and any excursions above the control limits are assessed and documented as part of this monthly review.
