(b)(4).Investigation results: the returned flexiva id 550 laser fiber was analyzed, and a visual evaluation noted that it was returned in one piece.The piece measured 277.9 cm from the end of the connector to the end of the exposed glass tip.The exposed glass tip measured 4.5 mm and appeared in good condition.There was distorted light from the sma connector, indicating a fracture within the fiber connector.No other problems with the device were noted.The reported event of "blast shield damaged" was not confirmed.The analysis of the returned device revealed that there was distorted light from the sma connector, indicating a fracture within the fiber connector.The exposed glass tip was in good condition.The blast shield is a component of the laser console.Only the laser fiber was returned for analysis.It is likely that procedural handling of the device during set-up or use contributed to the fracture within the fiber connector.A broken fiber within the connector of the device can result in insufficient aiming beam and low laser energy output, up to a complete inability for the fiber to fire.Review and analysis of all available information indicated that the root cause is adverse event related to procedure.A review of the manufacturing documentation for this device revealed that no anomalies or deviations related to the event occurred during manufacturing.A labeling review was performed and, from the information available, this device was used per the instructions for use (ifu) / product label.

It was reported to boston scientific corporation on july 9, 2021 that a flexiva id 550 laser fiber was used in a holmium laser enucleation of the prostate (holep) procedure in the prostate performed on (b)(6) 2021.The laser unit used was a lumenis moses 2.0 laser console with laser settings of 2 joules and 50 hertz.During the procedure, debris were found in the blast shield and was severely damaged.The procedure was completed with a different device.There were no patient complications reported as a result of this event.Note: this event has been deemed a reportable event based on the investigation finding of the laser fiber broken within the connector.
