As reported, the balloon of a 5f mynx control vascular closure device (vcd) ruptured during prep.There was no reported patient injury.Hemostasis was achieved by manual compression for twenty minutes.The mynx vcd was prepped according to instructions for use (ifu).The femoral artery¿s suitability was verified on angiography or venography, including the insertion angle (30-45 degrees) of the 5f non-cordis vascular sheath introducer.The vessel type was femoral arterial.The vessel diameter was verified to be greater than or equal to 5 mm in diameter.There was no presence of calcium in the vicinity of the puncture site.There was no vessel tortuosity.The device was used after an diagnostic/ interventional peripheral procedure using a retrograde approach.The deployer is mynx certified.Other procedural details were requested but are unknown, unavailable, not answered, or not applicable.The device will be returned for evaluation.

Complaint conclusion: as reported, the balloon of a 6f/7f mynx control vascular closure device (vcd) ruptured during prep.There was no reported patient injury.Hemostasis was achieved by manual compression for twenty minutes.The mynx vcd was prepped according to instructions for use (ifu).The femoral artery¿s suitability was verified on angiography or venography, including the insertion angle (30-45 degrees) of the 5f non-cordis vascular sheath introducer.The vessel type was femoral arterial.The vessel diameter was verified to be greater than or equal to 5 mm in diameter.There was no presence of calcium in the vicinity of the puncture site.There was no vessel tortuosity.The device was used after a diagnostic/ interventional peripheral procedure using a retrograde approach.The deployer was mynx certified.Other procedural details were requested but are unknown, unavailable, not answered, or not applicable.A non-sterile ¿mynx control vcd 6f/7f¿ involved in the reported complaint was returned for investigation.Visual inspection of the received device showed that button 1 and button 2 were not depressed.The syringe and procedural sheath were not received for evaluation.The stopcock was observed opened, and the balloon was found fully deflated.In addition, the sealant was found in its manufactured position fully covered by the sealant sleeves, the sealant was not exposed to blood.In addition, no damages were observed on sealant sleeves assembly.Per functional analysis, an inflation/deflation test was performed per the mynx control ifu.The results revealed a leak in the balloon of the returned device.Per microscopic analysis, visual inspection at high magnification revealed a longitudinal tear in the balloon of the returned device and the sealant was found in its manufactured position fully covered by the sealant sleeves, the sealant was not exposed to blood.In addition, no damages were observed on sealant sleeves assembly.The reported event of ¿balloon-balloon loss of pressure¿ was confirmed through analysis of the returned device.However, the exact cause of the longitudinal tear 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.
