Manufacturer Narrative

Device/media analysis: the jetstream xc-2.4 device was received by boston scientific for analysis.The guidewire was not returned in or with the device.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).A.014 test thruway guidewire was inserted into the device and transcended through the lumen with no issues.The device primed as designed.The device was activated, and the blades did not spin.The devices motor was heard; however, no tip rotation was observed.The devices control pod was opened to inspect for damage.It was noticed the pinion gear moved along the driveshaft and was not in contact with the motor gear.When the pinion gear slides off the shaft and does not contact the motor gear, rotation of the tip will stop.The presence of adhesive on the pinion gear was verified.The gear was slid back on the shaft and the device was activated.The device ran with the blades spinning for 2 minutes, with no issues of the gear moving off the shaft.Device analysis determined the condition of the returned device was consistent with the reported information of blades not spinning.The complaint was not confirmed for guidewire sticking issues.
