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.This is the only complaint reported to date for this lot number and failure mode.Investigation summary: the device was received for evaluation.A visual inspection found frayed fibers on the balloon.The device was inflated and water was seen exiting the balloon.The fibers were stripped away and a longitudinal rupture was noted on the balloon.Therefore, the investigation is confirmed for frayed fibers and for a longitudinal rupture.However, the investigation is unconfirmed for the reported hole in the catheter shaft as no holes were noted.Additionally, the investigation is inconclusive for the reported retraction issues through the sheath, as no retraction-related damage was noted to the device and as the original sheath used in the procedure was not returned for evaluation.It is likely that the identified balloon rupture resulted in the fiber disturbance.However, the definitive root cause for the identified rupture or reported issues 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.H10: d4 (expiry date 10/2019), g4.H11: h3, h6 (results 1, conclusion 1).H6 (added 1546 device code).H11:section a through f - the information provided by bd represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bd.
