A visual and dimensional inspection was performed on the returned device.The reported failure to advance could not be tested as it was based on operational context.The reported material separation was confirmed.A review of the production records and the corrective and preventive actions (capa) was performed and revealed no indication of a product quality issue.Additionally, a query of the complaint handling database for the reported lot revealed no indication of a lot specific issue.The investigation determined the reported difficulties appear to be related to the operational context of the procedure.It was reported that the stent delivery system (sds) failed to advance due to interaction with the patient¿s heavily calcified, heavily tortuous, and 90% stenosed lesion.Manipulation of the sds, during its interaction with the anatomy, may have contributed to the reported shaft separation.Analysis of the returned device noted the fracture face of the separation to be oval and jagged.This type of damage is consistent with a separation at a kink.It is likely that the guide wire kinked during the procedure, then subsequent movement of the device resulted in the separation.There is no indication of a product quality issue with respect to manufacture, design, or labeling.Additional information: d4 - model # added.Corrections: d1 - brand name updated.D2a - common device name updated.D3 - name updated.D3 - address, city, postal code updated.
