Manufacturer Narrative

Due to the automated manufacturing execution system (mes) system there are controls in the manufacturing process to ensure the product met specifications upon release.During analysis, the returned device was visually inspected that the stent was returned in its deployed state and there were no anomalies noted.A functional test was not performed as the stent had been deployed.The reported event is covered in the device directions 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 stent was returned in its deployed state confirming the event, there were no anomalies noted to the stent.It is probable that there were difficulties in advancing the stent through the catheter/ during insertion, causing the premature stent deployment.An assignable cause of procedural factors will be assigned to the reported and analysed 'stent deployed prematurely during use', as the issue is associated with a product that meets stryker design and manufacture specifications and was used in according with the dfu but due to procedural and/or anatomical factors during use, the product performance was limited.
