If you're using Magics or Simpleware there is/was a meshing tool embedded into the tool. That'll give a decent tet volume mesh. No idea about inflation as I've not spoken to their technical/development team in a fair while. 

Otherwise I'd be looking at Fluent Meshing (well, a colleague would - I've not quite figured out how the objects work) to remesh the surface, cap and volume mesh.
