Investigation ¿ evaluation: a review of the complaint history, device history record, documentation, drawing, instructions for use (ifu), manufacturing instructions, quality control, specifications, and a visual inspection/dimensional verification of the returned device were conducted during the investigation.The visual inspection of the returned device confirmed one 22.0 french catheter in a used condition.The device was returned with the drainage stiffener fully inserted.There appears to be biomatter on the distal portion of the catheter and stiffening cannula.There are four crude drainage holes beneath the specified five suture holes; it appears that the customer may have modified the device.Upon removal of the stiffener, no resistance was encountered.Biomatter was present on the drainage stiffener.The reported crack was located at the distal tip of the drainage stiffener; the crack runs 1.6cm down shaft starting at the distal tip.There also appears to be a second crack, 8mm in length, also running length-wise down the distal tip.The stiffener taper length measured to be 15mm and the catheter length measured at 40cm.The stiffener outer and inner diameters and the catheter inner and outer diameters were all found to be within manufacturing specifications.The end-hole of the stiffener could not be gathered due to the damage.Additionally, a document based investigation evaluation was performed.There is no evidence to suggest the product was not made to specifications.The drainage catheter and stiffener are matched through the manufacture and the tip is examined for damage at multiple points.There are no identified gaps in the manufacture and quality controls at this time.A review of the device history record showed no nonconforming events which could contribute to this failure mode.It should be noted there were no other reported complaints for this lot number.Ifu: ¿warnings ¿ if a catheter has become malpositioned or if drainage ceases, the catheter should be promptly exchanged or removed.¿ ¿how supplied ¿ store in a dark, dry, cool place.Avoid extended exposure to light.Upon removal from package, inspect the product to ensure no damage has occurred.¿ based on the information provided, the examination of the returned product, and the results of our investigation, a definitive root cause is product use and handling (possible-product received excessive pressure/actual-product modified after distribution).The appropriate personnel have been notified, and this failure mode will continue to be trended.Per the quality engineering risk assessment, no further action is required.
