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: one lutonix 018 drug coated balloon returned for evaluation.No specific anomalies were noted during the visual evaluation.The balloon was attempted to be inflated with an in-house presto inflation device during functional testing, but it was unsuccessful.The dried contrast within the inflation luer was observed under microscopic examination.It was further attempted to remove the contrast from the luer with the in-house tool, but it was unable to remove.No further testing was performed.Therefore, the investigation for the reported inflation issue, material deformation, and balloon rupture remains inconclusive as the functional testing couldn't be performed fully due to the dried contrast found within the inflation luer of the returned catheter, and no further testing could be performed due to the condition of the device.A definitive root cause for the reported inflation issue, material deformation, and balloon rupture could not be determined based upon the provided information.Labeling review: a review of product labeling documentation (e.G., procedural instructions, indications, warnings, precautions, cautions, possible complications, contraindications, nursing guide, and unit label) did not find any product labeling inadequacy.Expiration date(expiry date: 05/2025).
