Exporting vtk into Blender

I have a VTK file that I have opened in ParaView. I want to open the same file in Blender.
Can I know the ways to do it?
Please find the files here:

Save your geometry as a .stl file.

I tried doing it. But there was no image/data shown in Blender.

Then it may be a blender issue. @Michael may be able to help though.
