Evaluation summary: medtronic conducted an investigation based upon all information received.The device was available for evaluation.Visual inspection noted that the jaws would not close upon actuation of the handle.The instrument body was removed from the shaft and disassembled for visualization of internal components and revealed that the firing handle linkage was forced through the channel tube lugs, suggesting that the instrument had been fired through the safety interlock.Due to the condition of the instrument, further functional evaluation was not performed.It was reported that there were issues with the loading or firing of the clips.The reported issue was confirmed.The product analysis noted evidence that the device was not used as intended.This issue can occur under the following conditions.When the firing handle has not been allowed to fully return to the home position after forming a previous clip.A single continuous handle compression is one of two firing methods described in the information booklet which accompanies each product shipment, if the handle is compressed at an accelerated rate, clips do not have enough time to enter the jaws and the instrument will lock preventing the jaws from closing without a clip.The manufacturing records for each device are thoroughly reviewed prior to release to ensure that it meets all medtronic quality specifications.The instructions included with this device provide the following guidance: confirm that the clip is positioned within the jaws and is free of other clips or obstructions before squeezing the handle to close the clip.However, rather than forceful compression of the firing handle under these circumstances, if the firing handle is fully released by relieving hand pressure, the interlock feature will disengage, the next clip will load, and the clip can be applied.Furthermore; if an attempt is made to forcibly fire the instrument while engaged in interlock after all the clips has been fired, the lugs are designed to break as noted.Medtronic submits this report to comply with fda regulations 21 cfr parts 4 and 803.Medtronic has made reasonable efforts to provide as much relevant information as is available to the company as of the submission date of this report.This report does not constitute an admission or a conclusion by fda, medtronic, or its employees that the device, medtronic, or its employee caused or contributed to the event described in the report.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.Medtronic will submit a supplemental report if additional relevant information becomes known.
