The subject device was not returned to keymed ltd. The following potential root causes were investigated: manufacturing defect; design issue; and use error (2 possible types). Manufacturing defect - the mouthpiece has not been returned and the batch is unknown. Therefore no manufacturing fault analysis can be undertaken. However, there are no other reported instances and due to the injection moulding process used, it would be expected that the whole batch would contain common defects. The ifu states the following caution: 'caution: do not use a mouthpiece that is damaged or deformed. Doing so may cause patient injury and/or equipment damage. Confirm that the mouthpiece and strap are free from cracks, deformations, discoloration or other irregularities. ' although it is unknown whether the check was performed or acted upon. In conclusion, a manufacturing defect is unlikely to be the cause of this event. (b)(4). The height of the portion that enters the patient mouth is 1. 6 to 2. 0mm larger than the predecessor, but it is doubtful this would increase the likelihood of damage to teeth. The design intent of the mouthpiece is such that it is not expelled accidently during use. In conclusion, a design issue is unlikely to be the cause of this event. Use error - patient tooth was weak prior to the procedure and care was not taken. The ifu states the following caution: 'before using the mouthpiece, check the condition of the patients teeth. In case of any irregularity, take additional care to prevent further trauma' it is unknown whether this check was performed or acted upon. In conclusion, it is possible that this type of use error is the cause of this event. Use error - forced removal of mouthpiece caused tooth to break. The description of event in accompanying email from olympus canada includes 'the patient injury was a result of post-procedure removal, with propofol sedation making it difficult for the patient to expel the device from their mouth on their own. ' there is no guidance in the ifu to take care when removing the mouthpiece. A caution will be added to the ifu advising users that care should be taken when removing the mouthpiece to prevent injury in the oral cavity. In conclusion, it is probable that this type of use error is the cause of the event, possibly in conjunction with the use error type above.
