Braided Asd Occluder

Hi all,

I would like to model braided asd occluder, I am a beginner in 3dexp. I am attaching the photo of the braided asd occluder to be modeled. Please let me know where I can get some tutorial on this , so that I can build up on that.  It would be grateful, if you help me in this regard.  Thank you in advance.
