Bisecting with a curve

Support Modeling
1

I understand that I can bisect a model using the bisect tool, but it appears to only work in a straight line. Is there a clean and simple way to bisect an object using a custom made plane as the bisect line? In the file I attached, I would like to bisect the sphere along the curve.
Thanks in advance…

not with the bisect tool, but you could use the curve plane as a knife with the knife project tool or the boolean modifier

1)Boolean: Duplicate sphere, make booleans with plane object, one difference, one intersect and you have top part and bottom part.
2)Knife project: Profile plane without faces and cut through. Rip(V) connecting edges.
