No, it has not been tested. He says he did the method in a single patient and no larger scale study has it. If you did it, you'd be paying to do a procedure that is at best experimental and not approved for humans, hence why it is not ethical from the doctor. He is selling a one hit wonder in a attempt to set himself above the rest of the profession, IF he is doing this out of a research environment.
If he was conducting a study to compare surgical methods, it would be a different matter and you could enroll in it. With this said, there is nothing wrong about him writting articles about the procedure.
I'm saying these things because I think this is unsafe for you, that is all.
