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 no clip in the first position of the channel.The returned sample appears used as there is biological material present on the device.Functional inspection was 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.No clip fired on the first attempt.This was repeated with the same result.On the third attempt, a clip was unable to load properly.There was no clip in the next position of the channel.Another attempt to fire was made, and no clip fired.This was repeated six more times with the same result.The sample was disassembled to inspect the internal components.The proximal end of the feeder was bent.One of the feeder tabs was also not shaped correctly as it was completely horizontal instead of being bent down.The sample was received with 1 clip remaining in the channel indicating that 14 clips were fired by the end user.The clips missing from the first position in the channel, the mis-formed feeder tab and the proximal end of the feeder being bent are indications that the clips were out of position and stacking on one another in the channel.The clip stacking prevented the clips from loading properly into the jaws of the applier.It could not be determined exactly how or when the clips came out of position.A capa 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 reported complaint of "clips stuck in applier" was confirmed based upon the sample received.One device was returned with no clip in the first position of the channel.Upon functional inspection, no clip fired on the first attempt.This was repeated with the same result.On the third attempt, a clip was unable to load properly.There was no clip in the next position of the channel.Another attempt to fire was made, and no clip fired.This was repeated six more times with the same result.The sample was disassembled and the proximal end of the feeder was bent.One of the feeder tabs was also not shaped correctly as it was completely horizontal instead of being bent down.The clips missing from the first position in the channel, the mis-formed feeder tab and the proximal end of the feeder being bent are indications that the clips were out of position and stacking on one another in the channel.The clip stacking prevented the clips from loading properly into the jaws of the applier.It could not be determined exactly how or when the clips came out of position.A capa has been opened to further investigate this issue.
