As reported, the balloon of a 6/7f mynx control vascular closure device (vcd) burst during prep.Therefore, the product wasn¿t available and manual compression was performed for 20 minutes and the patient recovered.There was no reported patient injury.The device was used in a transfemoral cerebral angioplasty (tfca) procedure.The device was opened in a sterile field.A 6f non-cordis sheath was used.The device was prepared and used in accordance with the instructions for use (ifu).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 device will be returned for evaluation.

After further review of additional information received the following sections have been updated accordingly: g3, g6, h1, h2, h3 and h6.As reported, the balloon of a 6f/7f mynx control vascular closure device (vcd) burst during prep.Therefore, the product wasn¿t available and manual compression was performed for 20 minutes and the patient recovered.There was no reported patient injury.The device was used in a transfemoral cerebral angioplasty (tfca) procedure.The device was opened in a sterile field.A 6f non-cordis sheath was used.The device was prepared and used in accordance with the instructions for use (ifu).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.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, and the sealant was not exposed to blood.In addition, no damages were observed to sealant sleeves assembly.Per functional analysis, the inflation/deflation test was conducted per the mynx control ifu.The findings indicated a balloon leak in the balloon of the returned device.Per microscopic analysis, upon visual inspection at high magnification, a longitudinal tear was discovered in the balloon of the returned device.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 condition found could not be conclusively determined during analysis.Based on the limited 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.
