Block e1: the initial reporter's address is (b)(6).Block h6: problem code a050702 captures the reportable event of snare loop unable to cut.Block h10: investigation results: a captivator large oval med stiff snare was received for analysis.Visual inspection of the returned device revealed that there were some bends in the working length (in proximal and medium section).Functional inspection was performed and when the device was connected to the 10 inch loop fixture, it contracted and extended without problems even with the bends noted.Dimensional inspection was performed and the device was inserted in the ring gauge and it passed without any problems even with the bends noted.Continuity test was performed and the device passed, indicating a proper connection.No other problems were noted.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.In addition, during the product analysis the device passed the functional, dimensional, and continuity tests.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 working length was noted to be bent at the proximal section.This most likely occurred due to an excessive force being applied in 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 condition.Based on the information available and the returned device analysis, the most probable root cause for the reported complaint is no problem detected.This code was selected as the most probable complaint cause since the reported event of "loop failure to cut" cannot be confirmed.A review of the device history record (dhr) was performed and confirmed that this device met all material, assembly and performance specifications.
