According to the report, "hp [handpiece] was fired and it would not work.So staff opened another hp and completed the case." additional information was requested via email on 04/06/2016.A reply was received on 04/06/2016 stating, "the handpiece tested fine.When he went to do the tmr, it did not fire.The second handpiece was readily available." a sample review was conducted on 04/21/2016.The returned handpiece was visually inspected.The hospital returned handpiece (b)(4); however, the original packaging was not returned.The report stated that the handpiece test fired without an issue but when the surgeon attempted to use it, it would not fire.Upon removing it from the bag, (b)(4) had the multifilament fiber pulled out from the distal end of the coupler.The ends of the multifilament fiber appeared to be charred.The coupler was then opened and it also appeared charred inside.The inside of the coupler had pieces of broken and charred fibers inside of it.It appears as though the multifilament fiber end became dislodged and the handpiece was fired before the multifilament fiber end came completely out of the coupler.The root cause remains unknown; however the issue noted was most likely caused from some kind of mechanical force dislodging the multifilament fibers from the coupler and then attempting to fire it.The manufacturing records for lot ta-04089 were reviewed and it was confirmed that all records were controlled, available for review, and met all specifications per the device master record.The ifu states, "each sologrip iii handpiece is a fragile surgical instrument.Use caution when removing contents from packaging and during use.Excessive stress or tension on the optical fiber contained in the handpiece may result in device damage or malfunction.Always place the laser console near the sterile field.Position the white fiber coupler near the operative site to minimize tension on the fiber when the handpiece is in use.".
