The reported device, used for treatment, was not returned to the designated complaint unit for independent evaluation, thus visual inspection and functional testing could not be performed.A relationship, if any, between the subject device and the reported event could not be determined.A review of the device history records showed there were no indications to suggest that the product did not meet manufacturing specification or would not be able to perform as intended.A complaint history review identified prior similar events.Factors that could have contributed to the reported event may be due to a deficiency of the pin driver where the laser weld that attaches the outer tube to the inner cylinder with the triangular geometry fails, causing the outer tube to spin without spinning the screw.If the product associated with this event is returned at a future date, this evaluation will be reopened for investigation.
