(b)(4).Batch # t92k0d.Investigation summary: the analysis results found that the er320 device was returned for analysis and upon inspection the jaws were found to be in a yielded condition.In an attempt to replicate the reported incident the device was functionally evaluated.Upon firing of the device, the remaining 12 clips were ejected due to the condition of the jaws.Finally, the instrument locked out as intended.In order to evaluate the condition of the internal components of the device, it was disassembled.Upon disassembling, no anomalies were found.Possible causes for the found condition of the yielded jaws may be caused by the device being closed over an existing hard object or clip, placing stress on the jaws causing them to distort or yield and not return to their original dimensions/position, or excessive application of torque to the jaws when positioning the device on a vessel.The reported complaint was confirmed.It is known from the history of the device that the condition of the jaws may lead dropping/ejected clips.A manufacturing record evaluation was performed for the finished device lot/batch number and no non-conformances were identified.
