The device history records have been reviewed and this lot met all release criteria.There was nothing found to indicate there was a manufacturing related cause for this event.This is the only complaint reported to date for this lot number and failure mode.Three segments of the device and one electronic video were returned and evaluated for evaluation.A visual inspection found a completed detachment in the outer catheter shaft.The detached distal portion of the catheter shaft and balloon was not returned.The inner guidewire lumen was found to be cut from the wire and was returned in two segments.Based on the video review, the device stuck on the guidewire could be confirmed.Therefore, the investigation is confirmed for the reported guidewire incompatibility.The investigation is also confirmed for catheter detachment.It is likely that the issues with the guidewire contributed to the outer catheter detachment.However, the definitive root cause for the identified guidewire issue could not be determined based on the available information.Labeling review: the review of the ifu (instructions for use), indications, warnings, precautions, cautions, possible complications, and contraindications showed that the product labeling is adequate.(b)(4).
