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: one conquest pta dilatation catheter was returned for evaluation.Bunching of the catheter shaft was noted near the proximal end of the balloon; no other specific anomalies were noted during the visual evaluation.On the functional testing, the returned balloon was inflated with the in-house presto inflation device to 8 atm and it maintained pressure; further, the balloon was inflated to 24 atm, which continued to maintain the pressure.Then the balloon was deflated, and it took 27 seconds for complete deflation, which is within the acceptable limit of the product performance specification.Then the balloon was cut under microscopic observation, the port holes were noted to be collapsed, and the glue bullet was not seated in the correct position.No other functional testing was performed.Therefore, the investigation for the reported inflation issue was unconfirmed as the balloon was able to inflate and maintain pressure at both 8 and 24 atm during the functional testing.The investigation was also unconfirmed for the reported slow deflation as the balloon deflation time took 27 seconds to deflate, which is within the acceptable limit of product performance specifications.However the investigation was confirmed for the identified bunching of the catheter shaft, as the bunching was visible on the returned device during the visual evaluation.A definitive root cause for the reported inflation issue, reported slow deflation and identified bunching of the catheter shaft 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.H10: d4 (expiry date: 06/2023), g3, h6 (device).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.
