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.The device was returned inserted through the user's introducer sheath for evaluation.A visual inspection device found a complete break to the proximal weld joint of the balloon.Additionally, the catheter inner lumen was stretched and the sheath tip was noted to be flared.Therefore, the investigation is confirmed for a complete break of the proximal balloon joint, as well as for sheath-related retraction issues.It is likely that the user perceived the weld break as a detachment.The definitive root cause for the identified weld break or retraction issue could not be determined based upon the available information.It is unknown if patient and/or procedural issues contributed to the reported event.The review of the ifu (instructions for use), indications, warnings, precautions, cautions, possible complications, and contraindications showed that the product labeling is adequate.
