Manufacturing review: a manufacturing review was not required as this is the only complaint reported to date for this product and lot.Investigation summary: one ultraverse035 pta dilatation catheter has been received for the evaluation.On the visual evaluation, the device was noted to be clean and no other specific anomalies were noted.On the functional evaluation, the guidewire lumen was flushed and the water was noted to be leaking from the inflation hub.On further, an in-house presto inflation device was used to inflate balloon but water was noted exiting from the guidewire hub.Balloon was cut and noted a slit to the inner guidewire lumen just proximal to the balloon, marker bands were also noted to be damaged and dislodged.No other functional testing performed.Therefore the investigation for the reported leak was confirmed, as the water was noted to be leaking from the inflation hub.The investigation for the identified inner guidewire lumen slit was also confirmed, as the slit was noted on the inner guidewire lumen of the balloon under the microscopic observation.The investigation for the identified marker band dislodgement was confirmed, as the marker bands were noted to be dislodged under the microscopic observation.A definitive root cause for the reported leak and the identified inner guidewire lumen slit, marker band dislodgement 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.(expiry date: 10/2023).
