Manufacturing review: the device history records were reviewed with special attention to the raw materials, subassemblies, manufacturing process and quality control testing.This lot met all release criteria.There was nothing found to indicate there was a manufacturing related cause for this event.Visual/microscopic inspection: the sample appears to be clean.The balloon size for this product is printed on the balloon hub of the catheter and identified the return sample as a 20mm x 4.5cm.No holes or catheter damage was identified.No anomalies were noted to the device.Functional/performance evaluation: the patency of the guidewire lumen was tested using an in-house 0.035" guidewire and it passed without issue.The balloon was attached to an in-house inflation device and inflated to nominal pressure and rate burst pressure without issues.The balloon then deflated without issues.The balloon was able to deflate in approximately 2 seconds, which meets the essential requirement of less than 60 seconds, per specification.This test was repeated two additional times, which were both successful.Each time the bifurcate was inspected and no leaks were noted to the catheter at this location.The bifurcate remained connected to the inflation device without issue.The inflated balloon was also inserted into water and negative pressure was applied with no leaks or aspiration noted.No leaks or any other issues were identified.Medical records review: medical records were not provided; therefore, a review could not be performed.Image/photo review: images/photos were not provided; therefore, a review could not be performed.Conclusion: the device was returned for evaluation.A visual inspection did not find any aspiration related defects.The balloon was inflated and deflated without any indication of aspiration issues.No leaks were noted at the bifurcate, and when the inflated balloon was inserted in water no water was aspirated through the balloon when negative pressure was applied.Therefore, the investigation is unconfirmed for the reported aspiration issue.It is unknown whether procedural issues involving the original inflation device used contributed to the event.The definitive root cause could not be determined based upon available information.Labeling review: the current instructions for use (ifu) states: warnings & precautions: never use force when advancing or retracting intravascular device without first angiographically determining cause for any resistance.Using force may damage catheter or cause injury to the patient (such as vessel perforation).Do not exceed maximum inflation pressure indicated on label.Excess inflation pressure can cause balloon rupture and the inability to withdraw catheter through introducer sheath.Withdrawing balloon through introducer sheath may damage balloon.Dilatation catheter preparation.Prior to use, the air in the balloon catheter should be removed.To facilitate purging, select a syringe or inflation device with a 50 ml or larger capacity and fill approximately half of it with the appropriate balloon inflation medium.Do not use air or any gaseous medium to inflate the balloon.Connect a stopcock to the balloon inflation female luer hub on the dilatation catheter.Connect the syringe to the stopcock.Hold the syringe with the nozzle pointing downward, open the stopcock and aspirate for approximately 15 seconds.Release the plunger.Repeat step #7 two more times or until bubbles no longer appear during aspiration (negative pressure).Once completed, evacuate all air from the barrel of the syringe/inflation device.Prepare the wire lumen of the catheter by attaching a syringe to the wire lumen hub and flushing with sterile saline solution.
