Qn#(b)(4).The customer returned one unit ae05ml autoend05 ml for investigation.The returned sample was visually examined with and without magnification.Visual examination of the returned device revealed that the sample was returned with its trigger partially engaged and its rotation tab bent.A clip was partially loaded incorrectly into the jaws of the applier as the clip was to the side of the pusher head (distal end of feeder).The indicator clip was in the next position in the channel.The sample appears used as there is biological material present on the device.First, the partially loaded clip was manually removed , and the trigger cycle was completed.Functional inspection was then performed on the returned sample by attempting to engage the trigger using hand pressure.Upon engagement of the trigger, an audible ratchet sound could be heard indicating that the internal ratchet ears are intact.The indicator clip fired indicating that no clips were remaining in the device.The sample was disassembled to inspect the internal components.The proximal end of the feeder was found bent.The sample was received with only the partially loaded clip remaining indicating that 14 clips were fired by the end user.There were no clips remaining in the channel for testing.The bent rotation tab, the partially loaded clip being to the side of the pusher head and the proximal end of the feeder being bent are indications that the clips were out of position and stacking on one another.The clip stacking prevented the clips from loading properly into the jaws.It could not be determined exactly how or when the clips came out of position.A non-conformance has been opened to further investigate this issue.The ifu for this product, l06072, was reviewed as a part of this complaint investigation.The ifu for this product states, "mishandling of appliers may result in improper load and/or closure of the ligating clip." the clip stacking prevented the clips from loading properly into the jaws.It could not be determined exactly how or when the clips came out of position.A nonconformance has been opened to further investigate the clip stacking issue.The reported complaint of "clips not loaded properly" was confirmed based upon the sample received.One sample was returned with its trigger partially engaged and its rotation tab bent.A clip was partially loaded incorrectly into the jaws of the applier as the clip was to the side of the pusher head (distal end of feeder).The indicator clip was in the next position in the channel.Upon functional inspection, the indicator clip fired indicating that no clips were remaining in the device.Upon disassembly, the proximal end of the feeder was found bent.The sample was received with only the partially loaded clip remaining indicating that 14 clips were fired by the end user.There were no clips remaining in the channel for testing.The bent rotation tab, the partially loaded clip being to the side of the pusher head and the proximal end of the feeder being bent are indications that the clips were out of position and stacking on one another.The clip stacking prevented the clips from loading properly into the jaws.It could not be determined exactly how or when the clips came out of position.A non-conformance has been opened to further investigate this issue.
