Trim peridoc surface with wire


I try to Trim periodic surfaces (Cylinders, Cones, Spheres ...), with wires. But if the wire cut the period, the trim failled.

I tried with MakeFace or BrepFeat_SplitShape, but any way works.
Can you help me ??

Maybe it helps to split the edge cutting the period, i.e. incorporating a vertex lying on the period?

Thank Fabian for your reply

Theses vertex already exist in my wire.
I think the problem come from the projection of the wire, because when a wire cut the period the projection of this wire is not closed in the parametric space.

How can I include part of the parametric boundary in the creation of the new wire ??
