How to model coil with bent axis in Inventor?

A similar problem as in http://grabcad.com/questions/how-to-model-gooseneck-in-inventor.
There is bent axis, and I have to make coil around it.

Or how to make something like this Toroidal coil or Continuous Spiral Spring on Circular Path?

Thank you

Check the links above the rest is just matter of time
Unfortunately Inventor is not that powerful as solidworks in this

Bent it along (to make toroidal coil) whole coil was bad idea.
