H10: manufacturing review: 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.Investigation summary: the device was returned.An inflation attempt was made and water was noted exiting the balloon in two locations near the distal cone.The fibers were stripped from the balloon and a partial circumferential rupture was noted in the barrel of the balloon.Additionally, a crack/hole in the balloon material was noted where the balloon bonds to the distal tip.Therefore, the investigation is confirmed for a circumferential rupture, and for a hole in the balloon material.The definitive root cause for the circumferential rupture or the hole in the balloon material could not be determined based upon 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.H10: d4 (expiry date: 04/2021).H11: h3, h6 (patient code: remove 1069 - break).
