Manufacturer Narrative

The suspect device has not been returned to olympus for evaluation and the investigation is in process.The lead technician stated it is the doctor's standard practice to remove non-olympus stents through the scope channel.He also stated the doctor's patient population consists of more complex and difficult cases, sometimes with altered anatomy.At times, when the doctor is removing the stent through the scope, the bending section is retroflexed because of the patients' abnormal anatomy.The lead technician stated it is possible this may be a contributing factor of the cap issues recently experienced.Once the investigation has been completed, a supplemental report will be submitted with device evaluation results.Investigation activities have been opened to manage the actions related to this report and any required mdr reporting.
