Adam Adamant? 
That's funny you posted that, because I've been listening to the audio book read by Caroline John. According to the book, he's some specialist surgeon who came to see the Doctor (and hopefully "open him up and poke around"). It's been a while since I've watched the episode so I don't recall if they mentioned that in the actual broadcast story.

I ended up watching my DVD of it, too. I think they just refer to him as a "hospital bigwig" and Doctor Henderson offers to let him examine the Doctor.
