Investigation - evaluation: a review of the complaint history, dimensional verification, device history record, manufacturing instructions, quality control and visual inspection of the returned device was conducted during the investigation.The visual inspection of the returned device reported one open package for returned.Partial catheter only returned approximately 7.3cm of catheter¿s distal end has been severed and not returned.Proximal segment measured 61.6cm.Based on ink band increments, catheter measured 68.9cm indicating measurement within specification prior to being severed.This catheter segment had the 050010 adapter tightened down on the proximal end.Point of separation had a pinched appearance and has been cut at an angle.This device appears to have been damaged by an instrument of unknown origin.The complaint device was returned therefore, an investigation evaluation was performed.There is no evidence to suggest the product was not made to specifications.Review of device history record shows no nonconforming events which could contribute to this failure mode.It should be noted there were no other reported complaints for this lot number.Based on the information provided an the results of our investigation, the failure happened inside the patient and patient needed additional procedure to remove the broken pieces.The product was returned for evaluation and the complaint is confirmed based on the investigation of the returned product.As per the evaluation, this failure is likely happened by some unknown instrument used in this procedure.The root cause is likely to be product use or handling caused by another device.We will continue to monitor for similar complaints.Per the quality engineering risk assessment no further action is required.
