The device involved was discarded by the facility and not returned for evaluation.Photographs were provided.The photograph revealed a slice in the lumen.The slice was reported to have been under the gauze dressing.The ballooning occurred after the lumen was clamped to prevent blood loss through the slice.As the device was implanted for approximately one year, the root cause of ballooning is most likely not due to a manufacture issue.Without an evaluation of the actual device, a definitive root cause cannot be determined.
