As reported, under fluoroscopy, the inner balloon was noted to have burst and the end of the angiovac cannula (outer balloon) was filled with contrast.The case proceeded without incident.The contrast was successfully removed via a percutaneous puncture of the outer balloon at the end of the case.The pt's condition was otherwise unaffected.The used device will not be returned to angiodynamics.

A review of the device history records for the reported lot was performed by (b)(4).The review revealed no abnormalities which could have contributed to the reported event.The angiodynamics complaint report was reviewed for the angiovac product family and the failure mode "balloon leaked/burst - intervention required." no adverse trends were identified.The angiovac cannula sample was not returned for evaluation.Although the root cause of the inner balloon burst issue is unable to be determined, it is potentially a result of the inner balloon bonding process to the cannula shaft.A contributing factor may be over-pressurization of the balloon by the end user.Product enhancements have since revised the balloon material and the bonding process.It cannot be determined if the cannula was used in accordance with its labeling.Directions for use (dfu) is provided with this device and contains the following statements: "adverse affects: this device, as do all extracorporeal blood vessel devices, has possible side effects, which include but are not limited to infections, blood loss, thrombus formation, embolic events, vessel damage and complications of percutaneous or surgical insertion techniques.These may occur if the instructions for use are not followed." (b)(4).Device not returned to manufacturer.
