Manufacturer Narrative

The flash mini device used in the procedure was returned to ostial corporation for evaluation.Inspection of the device found a small leak in the distal portion of the proximal balloon, confirming the site reported balloon burst.The returned device was missing the stopcock which was likely removed to accommodate the manifold and 10 ml syringe that were reported as being used in this case, instead of the provided stopcock and 1.0 cc (ml) pressure relief syringe intended to be used for inflating the proximal balloon.While there was a small leak in the balloon, it was still able to be fully inflated to the nominal inflation volume and there were no obvious signs of manufacturing issues that would have caused or contributed to the leak/burst.The site reported that the recommended contrast/saline media were used to inflate the balloon; however, it is possible that some air may also have been introduced due to use of the manifold or during device preparation, and when the balloon burst, that air was released causing the site reported air embolism.In addition to reviewing the case details and inspecting the returned device, ostial corporation reviewed the manufacturing documentation and lot release testing associated with the flash mini device lot that was used in this procedure.The balloon burst and fatigue test results were found to be within specification and no other issues were noted that would have caused or contributed to the reported incident.Historic complaint and manufacturing records were also reviewed, and it was confirmed that the incidence of balloon burst and air embolism have not exceeded the expected rates in the product risk management files.The instructions for use (ifu) for the flash mini was also reviewed and it was confirmed that there are instructions to use the supplied 1.0cc (ml) syringe with pressure relief feature to inflate the proximal balloon and not to switch to other inflation devices.The potential adverse events in the ifu were also reviewed and confirmed to include air embolism.Based on the investigation results, there is no indication that the flash mini device did not perform as intended.The root cause for this incident is likely related to inflation of the balloon using the manifold and 10 ml syringe, instead of the provided stopcock and 1.0 cc (ml) pressure relief syringe called for in the device ifu.

Event Description

The event description was provided to ostial in an email received from fda for the user facility report mdr#: 1001760000-2022-8008.The event description in the mdr indicated the proximal balloon burst due to the use of a standard manifold syringe for injection (10 ml) instead of the supplied syringe called for in the ifu (1 ml) which may have inadvertently caused the balloon to burst.Additionally, an "air embolism" was observed by the physician traveling down the coronary artery.Per the mdr report, this did not cause any permanent adverse outcomes and required only initial monitoring to prevent harm.
