Manufacturer Narrative

Block h6: impact code f1001 is being used to capture the reportable problem of aborted/cancelled procedure.Block h10: investigation results an alair bt catheter was received for analysis.Visual and microscope inspection of the returned device revealed no defects along the power cord, handle and shaft.In addition, the red and yellow tc wires were found correctly soldered to the solder pads.However, when the electrode array was visually inspected in both relaxed and expanded state, one electrode array was kinked which indicates that the device failed the electrode array angle measurement test.Functional test was performed and device was connected to the rf controller; the ready light turned from amber to green.The device was then activated and cycled through 10 activations.The device passed the functional test without the generation of any error messages, which indicates that there were no defects to the device, array, solder pad and t.C.Wires.The units passed the functional test.Media inspection of the photo provided by the customer revealed that the loop was in an extended position and no problems were noted.No other device problems were noted.The reported complaint of device incomplete activations could not be confirmed since the device can activate through 10 activations.The reported complaint of device catheter electrode array icon flashes amber could not be confirmed since the device was connected to the rf controller; the ready light turned from amber to green.Therefore, these events are classified as "no problem detected" since the complaint cannot be confirmed.Additionally it was found that one electrode in the array kinked and the device failed the electrode array angle measurement test.This kink was likely to have occurred due to the manner that the device was handled and manipulated that may have caused the reported and encountered failure.Excessive manipulation of the device without enough care could have induced the defect found.Based on the information available and the returned device analysis, the most probable root cause for the reported complaint is adverse event related to procedure because the adverse event occurred during the procedure and the device had no influence on the event.A review of the device history record (dhr) was performed and confirmed that this device met all material, assembly and performance specifications.Block h11: block b5 has been updated based on additional information received august 26, 2022.
