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 for evaluation.A visual inspection found the outer pebax layer to be peeled from the balloon throughout the balloons length.Additionally, the circumferential fibers were noted to be unraveled from the balloon.The device was inflated and water was seen exiting the balloon from a pinhole rupture.Therefore, the investigation is confirmed for both peeled pebax and unraveled fibers, as well as for a pinhole rupture.Per the reported event details, the vessel being treated was 'massively calcified.' therefore, it is possible that patient factors contributed to the identified fiber and pebax issues.However, the definitive root cause for the identified issues could not be determined based upon available information.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).
