As reported, the balloon of a 6f/7f mynxgrip vascular closure device ruptured upon pulling the device back prior to sealant deployment.The device was removed intact and manual compression was held for hemostasis.There was no reported patient injury.The device was opened, stored, and prepped in a sterile field per the instructions for use (ifu).The deployer was mynx certified.The device is not being returned for evaluation as it was discarded at the facility.The reported event of ¿balloon-balloon loss of pressure¿ could not be confirmed as the device was not returned for analysis.The exact cause of the issue experienced could not be determined.Based on the information available for review, access site vessel characteristics (although not reported) and/or sheath condition factors (ruptured upon pulling the device) are possible since calcification/peripheral vascular disease (pvd) at the access site and/or a frayed/damaged sheath tip can cause damage to the balloon, resulting in a loss of pressure.According to the mynxgrip ifu, which is not intended as a mitigation, ¿the safety and effectiveness of the mynxgrip have not been established in the following patient populations: patients with clinically significant peripheral vascular disease in the vicinity of the puncture.¿ also stated in the ifu during product preparation, ¿confirm via femoral arteriogram or venogram: common femoral artery or vein single wall puncture.Evidence of adequate flow.There is no evidence of significant pvd in the vicinity of the puncture.¿ additionally, users are instructed to discard the device if the balloon does not maintain pressure.Based on the information provided, there is no indication 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.
