One bi-directional, curve d-d, tacticath sensor enabled contact force ablation catheter was received for evaluation.Visual inspection revealed electrode 2 was displaced from its original location and was separated from conductor wire 2.The catheter was connected to an ensite precision system and electrode 2 appeared distorted and read as an open circuit during electrical testing.Electrode ring 2 was distally displaced on the shaft and was separated from conductor wire 2, consistent with the open circuit and display issue.The device history record was reviewed to ensure that each manufacturing and inspection operation was performed.The cause of the displaced electrode ring is consistent with damage during use.
