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 20 minutes.The device was trying to use after an interventional peripheral procedure using a retrograde approach.The physician was being trained on using the device.The device was stored according to the instructions for use (ifu).The device storage temperature did not exceed 25 °c.The mynx vcd was prepped according to ifu instructions.The syringe provided was used to inflate the balloon.The balloon was inflated with 3ml of saline.The device looked okay after removing from the package.The femoral artery¿s suitability was verified on angiography or venography, including the insertion angle (30-45 degrees) of the 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 presence of calcium in the vicinity of the puncture site.A 5f non-cordis sheath was being used.The device will be returned for evaluation.
