Device evaluated by mfr: the jetstream device xc-2.4 was received by boston scientific for analysis.The shaft and the remainder of the device were inspected for damage.Visual examination showed no shaft damage.The functionality of the device was checked by setting up the product per the instructions for use (ifu).The device was primed and activated.The blades spun as designed for a period of 2 minutes in the blades down mode with no issues.The device then entered into the blades up mode and ran for a period of 30 seconds and the blades stopped spinning.The motor on the device was heard, but the blades were not spinning.The device's pod was opened to inspect for damage.The pinion gear had slipped off the drive shaft.When the pinion gear slides off the shaft and does not contact the motor gear, rotation of the tip would stop.Device analysis determined the condition of the returned device was not consistent with the reported information of priming and error issues.The complaint about bubble errors was not confirmed; however, blades not spinning due to the gear sliding off the shaft was revealed.
