OpenFOAM blockmesh meshing and deleting the unwanted sections is what I recommend, but you may also try ICEM.

Gokhan Altintas

There are many ways, but need to knowledge related with file type, and state of manifold. if I have time I can check it or mesh it. I worked with trabecular bone structures with several millions elements. and what is your needings as element type and intensity etc.
