Hi Camilla,
My apologies, I think that I did not understand your problem properly. The stent will be crimped, displaced (travel through the vessel), and will be deployed at the desired location. For displacing the stent on the guidewire you will need to model the contact between the guidewire and the stent and then apply displacement at one end of the stent and the stent should bend while moving through the path.
If you can share snapshots of the assembly, I may be able to comment more.
Regards,
