How can I bend my model?

Hello

I‘m new to sw. I'm meeting a question now while I was making my model. Please see the attached imaged. I'm going to bend the model in the circular shape and make the hole A and D together as well as  hole B and C together, like the coincident mate.  Then my model should be like the medical stent and it can be foldable.

So my quesiton is how can I bend my model and can make the holes that are mentioned connect together?

I have attached my model in the zip file. Its name is assem2.

Thank you for your time. I'm looking forward to your reply.

PS: Have a good Chrismas day.
