Due to the automated manufacturing execution system (mes) there are controls in the manufacturing process to ensure the product met specifications upon release.During visual inspection, the stent was returned deployed and noted to be deformed.The sdw (stent delivery wire) was noted to be kinked/bent.The stent was noted to be broken/fractured.The sdw was noted to be broken/fractured.The introducer sheath distal tip was noted to be damaged.Functional inspection could not be performed as the stent was deployed.The reported event is covered in the device direction for use (dfu).As well, the risk of the reported event is documented in the risk documentation and there are current controls to mitigate the risk of the as reported event.The reported stent difficult/unable to advance or pullback through catheter could not be duplicated; however, the analysis results are consistent with the reported event.The reported stent broken/fractured during use was confirmed during the analysis.The device did not meet specifications when received for complaint investigation based on visual inspection.The device was analyzed.The stent was found to be deployed, broken/fractured and deformed.The sdw was found to be kinked/bent and broken/fractured.The tip of the stent introducer sheath was found to be damaged.The event description indicated that the subject stent was being used in a stenosis case which is not recommended.The subject stent dfu states "the stent system is intended to be used with occlusive devices in the treatment of intracranial aneurysms".An assignable cause of procedural factors will be assigned to the as reported stent difficult/unable to advance or pullback through catheter, as reported/as analyzed code stent broken/fractured during use, and to the as analyzed codes stent deployed prematurely during use, stent deformed, sdw broken/fractured during use, introducer sheath distal tip damaged and sdw kinked/bent as this complaint appears to be associated with a product that met stryker design and manufacturing specifications and was used in accordance with the dfu, but performance was limited due to procedural factors during use.
