Manufacturer Narrative

Block d4, h4: the complainant was unable to provide the suspect device lot number; therefore, the lot expiration and device manufacture dates are unknown.Block h6: problem code 1198 captures the reportable event of device delivers energy intermittently.Problem code 2587 captures the reportable event of loop failure to cut.Block h10: the returned rotatable snare was analyzed, and a visual evaluation noted that no damages were found.A functional evaluation noted that the device was able to extend, retract, and rotate without any problem.A continuity test was also performed and the device passed the continuity test since the device's electrical resistance was within specification, indicating a proper connection.No other issues with the device were noted.The reported event of device delivers energy intermittently was not confirmed since the device passed the continuity test upon return.The reported event of loop failure to cut was not confirmed since the device cannot be functionally evaluated with respect to anatomical/procedural factors encountered during the procedure.The product record review confirmed that this is not a new failure type and the risk is anticipated.There was no evidence of a manufacturing issue, design or user issue which could have caused the complaint.Based on the information available, the investigation concluded that the most probable cause is no problem detected.A review of the manufacturing documentation for this device was unable to be performed as the lot number is unknown.However, a ship history review was performed to identify the most probable lots and a manufacturing review of the most probable lots did not identify any anomalies or deviations that could have contributed to the event.
