As reported, the balloon of a 5f mynx control vascular closure device (vcd) burst during prep.Therefore, the product wasn¿t available and another mynx control device and recovered.There was no reported patient injury.The device waws prepped and used in accordance with the instructions for use (ifu).The mynx vcd was intended to be used in a percutaneous transluminal coronary angioplasty (ptca) using a retrograde approach.There were no visible signs of device/package damage prior to use.The physician achieved certification on the use of mynx and has used the device several times prior to this procedure.The femoral artery¿s suitability was verified on angiography, including the insertion angle (30~45 degrees) of the vascular sheath introducer.The vessel diameter was verified to be greater than 5mm in diameter.The puncture site did not have visible calcium/plaque.There was no stent near the puncture site.The vessel did not have stenosis >50% at the puncture site.The target femoral site was not previously closed with any closure less than 30 days prior to this procedure.There was no evidence of pre-existing hematoma, arteriovenous fistula, or pseudoaneurysm at the access site prior to use mynx control.Button one was not pressed because the device was not available to be used due to the balloon rupture.The device will be returned for evaluation.

Complaint conclusion: as reported, the balloon of a 5f mynx control vascular closure device (vcd) burst during prep.Therefore, the product wasn¿t available and another mynx control device and recovered.There was no reported patient injury.The device was prepped and used in accordance with the instructions for use (ifu).The mynx vcd was intended to be used in a percutaneous transluminal coronary angioplasty (ptca) using a retrograde approach.There were no visible signs of device/package damage prior to use.The physician achieved certification on the use of mynx and has used the device several times prior to this procedure.The femoral artery¿s suitability was verified on angiography, including the insertion angle (30-45 degrees) of the vascular sheath introducer.The vessel diameter was verified to be greater than 5mm in diameter.The puncture site did not have any visible calcium/plaque.There was no stent near the puncture site.The vessel did not have stenosis >50% at the puncture site.The target femoral site was not previously closed with any closure less than 30 days prior to this procedure.There was no evidence of pre-existing hematoma, arteriovenous fistula, or pseudoaneurysm at the access site prior to use mynx control.Button one was not pressed because the device was not available to be used due to the balloon rupture.A non-sterile ¿mynx control vcd 5f¿ 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.The balloon was found fully deflated.In addition, the sealant was found in its manufactured position, fully covered by the sealant sleeves and the sealant was not exposed to blood.In addition, no damages were observed to the 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 return device and the sealant was found in its manufactured position, fully covered by the sealant sleeves and the sealant was not exposed to blood.In addition, no damages were observed to the 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.
