Block h6: imdrf device code a090402 captures the reportable event of snare unable to deliver energy.Imdrf device code a050702 captures the reportable event of snare loop cutting problems.Block h10: investigation results a sensation short throw snare was received for analysis.Visual inspection of the returned device revealed no problems.Dimensional inspection of the 2 in 1 was compared with the go no go fixture (active cord gauge) and it was within expectation.Functional inspection was performed and when the device was connected to the 10-inch loop fixture, it could extend and retract well.Electrical test was performed, and the device passed, indicating a proper connection.No other problems were noted.The reported complaint of loop failure to cut could not be confirmed since the device cannot be functionally evaluated with respect to anatomical/procedural factors encountered during the procedure.The reported complaint of failure to deliver energy since the device passed the electrical test.Device analysis found no problems with the device during visual and functional test.Based on the information available and the returned device analysis, the most probable root cause for the reported complaint is no problem detected.
