that would depend on what you wanted out of the model. if you want a great deal of accuracy, it will take a lot of work. if you just want it to look pretty good, you can probably get there with a straight spring and the deform feature.
Draw a curve on a plane. Then draw a circle on that plane offset from the curve. Then Sweep:
Sorry Matt but on this case - this not work The pitches will not be oblique to the spring axis
I do not think it is possible in the real world because value is too small.

Its only ~0,01 mm. Nanotechnology goes much deeper.

..yah.. deform.. ... but. that .0005 offset value...strange?
Just ignore the 0.0005 inch. I just want a slanted spring. Any dimension is fine
This is what I was looking for. May I have the part please?

I think you may have missed the entire point of the forum - it's to help teach each other how to do things not do someone's work for them.

Jim I completely agree. I don't even want to write "magic word" Only subject:
And waiting for ready part. Best at a bar
And then don't even want to click "Like" or select the correct answer.
no comment ;-)
Thanks for posting Paul. This technique will be useful for a different application I have that has nothing to do with springs.

Wonky!.. very kewl! and, thanks for sharing!
..btw.. the unfortunate issue you and others may see/experience,.. is our limitation with overlap...and for this sweep or coil to look more real.. the sweep would be more/less touching.... ..and,..there is a trick... "Thicken".. 
When I first tried with a slightly larger wire diameter, the circular profile changed to several varying *wonky* shapes along the path and the results even skipped pitches and reconnected by a straight line even when there was no chance of overlap. Haven't tried but maybe thicken is a workaround. Does anyone want to spend their time campaigning to get that fixed?
Also this can be done without using model modifying tool (Deform). But OP's requirement cannot be done without Deform tool.
There's an easier more direct way. You can sketch the path as a single angled line or as shown below as an angled line, tangent arc, angled line. Sketch also the cross section of the wire, and use the Profile Twist option .

Sorry Matt:
But I agree with you, modeling an "accurate" spring is usually not required. And I'm not really sure you can do it with any real accuracy without a lot of work. By bending the stock you are changing the diameter and length of the stock. So, if you measure the length of the spring, it'll be different than the real thing.
I've been part of the forum for almost a year. I have asked many how-to questions because I want to learn, not because I want someone else to do the work. I can model a straight spring but not a slanted one, and therefor, I asked for help. Please try not to spread false assumption around. Thank you.
If you are a mathematician, you can define an equation driven curve in a 3D sketch to use as sweep path.
Thank you for the part. It's a great technique. With the Flex command, I was able to model a twisted spring.
Here is video of doing it in Inventor. SOLIDWORKS should be basically the same.
I thought about it but couldn't find any parametric equations that represent a slanted spring.

...I honestly think many of us have wanted/request/campaigned/voted for allowing overlap/interference (nonmanifold).. but the 3D kernel is owned by another company... so, it seems,.. we are SOL?
anyhow... there are workarounds.. just painful (and fun in a weird sadistic way?)
you would likely need to make your own by adding 2 (or more) sets of equations together...
