Equation driven line help!

Hi All,

I'm trying to draw a stent, and have begun by using a equation driven curve to produce a sine wave. I now need to join the waves up with struts, however when I sketch the struts, the trim feature is not available due to the curve, so I am forced to connect it through a rectangle, which remains visible after extrusion.

If anyone could give me advice on how to somehow join the struts in a homogneous fashion to the waves (or a better way of drawing the sine curve), it would be much appreciated!

I've attached the files to better demonstrate my issue.
