Patient's date of birth unavailable.Device evaluation: the device was returned to the manufacturer and evaluated on 11 december 2019 and re-evaluated on 15 january 2020.During the evaluation, the shaft of the device was slightly bent but holds shape set, the blades of the device are slightly retracted into the shaft and slightly non concentric.Inspection of the device's handle shows the trigger pin in the far track and not in the home position, with barrel shavings identified throughout the device.Constant force spring and trigger pin of the device are in good condition, with the left distal trigger tab showing slightly more wear than right distal trigger tab, both right and left proximal trigger tabs have normal wear.In the barrel shaft of the device, the pin rode out of the track onto the barrel, located on the far track return path.The sleeve tab of the device is not in the proper position, and the barrel is slightly proud of the sleeve in the far track.The barrel does not pass the drop test due to biologics located in the devices barrel and marring on the far track return path.When attempting to rotate the device's inner shaft, the inner shaft can be removed from the outer shaft.During the final device evaluation on 15 jan 2020, the device's guide pin was confirmed to be worn from both distal and proximal ends and a portion of the guide pin material was missing.This wearing caused a mechanical lock up between the blades and shaft of the device.This prevented the blades from rotating as intended and was the cause of the experienced failure.

A lead extraction procedure commenced to remove one right ventricle (rv) lead due to non function; five other leads were present but they were not targeted for extraction.The subclavian to superior vena cava (svc) was occluded making it difficult to advance a spectranetics 14f glidelight laser sheath.Since the glidelight was unable to move through the subclavian, a spectranetics 11f tightrail mini was used to clear the occlusion.After advancement was made with the tightrail mini, a spectranetics 16f glidelight laser sheath and spectranetics visisheath were introduced into the subclavian.The glidelight laser and visisheath then stalled making little to no progress.After the glidelight laser and visisheath stalled the tightrail mini was reintroduced back into the subclavian.This device made slow progress through the occlusion.It was during this advancement that the handle of the tightrail mini stopped triggering making the blades unable to actuate.A new spectranetics 11fr tightrail mini was introduced back into the subclavian, this new tightrail mini made slow progress and then stalled.The physician then elected to try a spectranetics 13f tightrail sub-c device followed by a spectranetics 16f glidelight laser sheath to successfully extract the lead.There was no reported patient harm during this procedure.This report is being submitted as a result of the final device evaluation of the tightrail mini, which occurred on (b)(6) 2020.During this evaluation, it was discovered that there was a portion of guide pin material missing from the device.This is now a reportable event due to the potential for embolism.
