Manufacturing review: a complete manufacturing review could not be conducted, as the lot number was not reported for this device.Investigation summary: the device was returned for evaluation.A visual inspection found unraveled fibers on the barrel of the balloon.The balloon was inflated with an in-house inflation device and a pinhole rupture was noted on the balloon.Therefore, the investigation is confirmed for unraveled fibers and for a pinhole rupture.The definitive root cause for the identified unraveled fibers or pinhole rupture 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.(removed device codes: 1262 - material frayed & 1454 peeled / delaminated; added device code: 1664 - unraveled material).
