I know in this answer it has been shown how to create a helix in animation nodes: How to make a rope winding animation? However, I'm wondering if there is anyway make a helix deform to the curves of a spline, achieving a similar result to the below image where I applied curve modifier to a helix curve.

All you have to do is change the basis of the parametric equation to the tangent, normal, and cotangent of the spline. The cotangent is computed by crossing the normal and the tangent vectors.

Node Tree

Note that the samples vectors are not normalized.
