Investigation - evaluation: a review of the complaint history, dimensional verification, device history record, , manufacturing instructions, specifications, quality control and visual inspection of the returned device was conducted during the investigation.The visual inspection of the returned devices reported thirteen unopened packages, one open empty package and one open package containing a used catheter.Used catheter was separated into 3 pieces.First point of separation occurred at 31cm, from the distal tip second separation point occurred at 31.7cm, the small segment between the severed point 7mm long, total length of catheter measured 69.8 cm.The catheter had all required ink marks indicating no missing pieces.Both severed separation points has mating fractures.During this investigation this catheter was acutely manipulated, we were unable to snapped or fracture the material.The remaining unopened devices were opened and manipulated, could not recreate incident.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, no product returned and the results of our investigation, a definitive root cause could not be determined.We will continue to monitor for similar complaints.Per the quality engineering risk assessment no further action is required.
