(b)(4).Investigation results: a captivator medium oval stiff snare was received for analysis.Visual inspection of the returned device revealed that the snare loop was detached from the distal cannula, however, the loop was not returned.No other problems were noted.The reported event of "handle break" was not confirmed since the analysis of the device found the handle was in good conditions.The product record review confirmed that this was not a new failure type and the risk was anticipated.There was no evidence of a manufacturing problem, design or user problem which could have caused the complaint.Upon product analysis it was observed that the loop was detached.Evidence of torque was noted on the cannula which shows that the process was done in the unit and that ensures that the components were attached.These types could occur during its manipulation and due to the force applied over the device.Most likely procedural factors as handling of the device, the technique used by the physician during initial use, set-up, power-up, or shortly thereafter could have affected its performance and its intended purpose, leading to the reported event.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.This is defined as the adverse event occurred during the procedure and the device had no influence on event.A review of the device history record (dhr) was performed and confirmed that this device met all material, assembly and performance specifications.
