One bi-directional, curve d-f, sensor enabled, advisor hd grid mapping catheter was received for evaluation.Electrodes 1-16 met specifications for acceptable resistance values with no open or short circuits detected.The device history record was reviewed to ensure that each manufacturing and inspection operation was performed.The cause of the reported error message and the subsequent delay remains unknown.
