As per the mb diagnostic catheters survey guidewire survey the respondent indicated that he had marker band movement that separated/dislodged.There was no reported patient injury.No additional information is available as this was a blinded survey.The products were not returned for analysis and a product history record (phr) review could not be performed because the lot number for this product is unknown.Without the return of the device or images for analysis, the reported customer event ¿marker band-dislodged¿ could not be confirmed.Procedural/handling factors such as entrapment of the catheter between other endovascular devices and the vessel wall or vessel characteristics may have contributed to this issue.Although not intended as a mitigation of risk, information for safety is provided in the products labeling with the intent to make the user aware of the risks.According to the instructions for use (ifu), ¿manipulation of the catheter under excessive friction due to interaction with other devices or while trapped in the vasculature, can lead to stretching or elongation of the catheter.Stretching or elongation of the catheter during endovascular procedures could result in the marker bands moving along the catheter.In extreme cases, marker bands may come off the catheter and dislodge into the vascular system.Avoid entrapment of the catheter between other endovascular devices and the vessel wall.¿ based on the information available and the phr, there is no indication that the event is related to the device design or manufacturing process.Therefore, no preventative or corrective actions will be taken at this time.
