A review of the complaint history, drawings, device history record, documentation, instructions for use (ifu), specifications, quality control, and visual inspection of the returned device was conducted during the investigation.One advance lp low profile balloon catheter was returned for investigation.Inspection of the device noted a pin hole located at the apex of the proximal end of the balloon.Bonds were smooth and free of damage and defects.The balloon measured within specifications and the working length measured within specifications.The balloon did not burst; it had a pin hole leak.There is no evidence to suggest the product was not manufactured to current specifications.Review of the device history record shows no nonconformance of released product.Based on the information provided and the results of our investigation, a definitive root cause could not be determined.Per the quality engineering risk assessment, no further action is warranted.Monitoring will continue to be performed for similar complaints.
