Complaint conclusion: as reported, the balloon of a 5f mynx control vascular closure device (vcd) leaked sterile heparin saline, during the device preparation procedure.The balloon ruptured.Hemostasis was achieved by another mynx device.There was no reported patient injury.There was no damage observed prior to opening the package.The device was prepared and stored according to the instructions for use (ifu).The femoral artery¿s suitability was verified on angiography or including the insertion angle (30-45 degrees) of the 5f non-cordis vascular sheath introducer.The vessel diameter was verified to be greater than or equal to 5 mm in diameter.There was no vessel tortuosity.There was no presence of calcium in the vicinity of the puncture site.The mynx vcd was used in diagnostic procedure with a retrograde approach.The deployer¿s mynx certified.Other procedural details were requested but are unknown, unavailable, not answered, or not applicable.A non-sterile ¿mynx control vcd, 5f (ce mark)¿ involved in the reported complaint was returned for investigation.Per visual analysis, the unit was thoroughly inspected observing that both button #1 and button #2 were not depressed.The syringe was attached to the device, and the stopcock was set to the opened position.The sealant remained in its manufactured position fully covered by the sleeves.The balloon was not inflated, and the atraumatic tip did not present any damages or anomalies.However, it was noted that the balloon was torn.No other outstanding details were noticed.Per functional analysis, an inflation/deflation test was performed by injecting water into the returned device according to the ifu.However, due to the observed torn condition of the balloon, the inflation process was not successfully.Per microscopic analysis, the balloon was inspected using a vision system to obtain a magnified image, and the torn condition was confirmed.The reported event of ¿balloon-balloon loss of pressure¿ was confirmed through analysis of the returned device.However, the exact cause of the torn condition found could not be conclusively determined during analysis.Based on the information available for review and product analysis, it is not possible to determine what factors may have contributed to the issue reported.However, as this issue was found during preparation of the device, handling factors during prep are possible.According to the ifu during the prepare balloon step, which is not intended as a mitigation, ¿fill locking syringe with 2 to 3 ml of sterile saline, attach to stopcock and draw vacuum.Check luer connector and tighten if necessary.Inflate the balloon until the black marker on the inflation indicator is fully visible.Check for leaks in the balloon and syringe connector; retighten if necessary.Discard the device if the balloon does not maintain pressure.Check for air bubbles in the balloon.If air bubbles are visible, deflate the balloon, draw vacuum to remove bubbles and re-inflate.¿ neither the product analysis, nor the information available for review suggest that the reported failure could be related to the design or manufacturing process of the unit.Therefore, no corrective/preventative actions will be taken at this time.
