(b)(4).During processing of this complaint, attempts were made to obtain complete event, patient and device information.Evaluation summary: the device was returned for analysis.The reported difficult to position, difficult to remove and shaft separation were confirmed.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no other similar incidents from this lot.The investigation determined the reported difficulties appear to be related to circumstances of the procedure as it is likely that the stent delivery system (sds) met resistance during advancement over the guide wire due to a buildup of procedural contaminants (blood, contrast), such that the inner member bunched; thus, causing the sds to become stuck on the guide wire and resulting in the reported difficult to position and the reported difficult to remove.Attempting to separate the devices using excessive manipulation resulted in the reported shaft/balloon separation and the noted inner member bunching.Based on the information reviewed, there is no indication of a product quality issue with respect to the design, manufacture or labeling of the device.
