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 dorado pta dilatation catheter has been received for the evaluation.On the visual evaluation, the device was appeared bloody and no other anomalies were noted.On the functional evaluation, the balloon was inflated to 8 atm using an in-house presto inflation device.Balloon maintained pressure and no water was noted to be leaking from the balloon, catheter and guidewire luer.Once the presto reached above 12 atm water was noted leaking from the guide-wire luer.A hemostat was placed on the catheter due to the issue being with the bifurcate and the presto was then pressurized again to view the bifurcate.Microscopic photos and video were taken noting a hole within the bifurcate.Therefore the investigation for the reported leak was confirmed, as the water was noted leaking from the guidewire luer during the functional evaluation.The investigation for the identified bifurcate break was also confirmed, as the water was noted leaking from the hole in the bifurcate.The identified bifurcate break is likely the root cause for the reported leak.However a definitive root cause for the identified bifurcate break and the reported leak 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: 01/2024).
