I'm reading The Way We Live Now and have a problem with this paragraph:

The one thing I'm sure I couldn't take, Jan said he said to her, is becoming disfigured, but Stephen hastened to point out the disease doesn't take that form very often anymore, its profile is mutating, and, in conversation with Ellen, wheeled up words like blood-brain barrier; I never thought there was a barrier there, said Jan.

I can't understand the bold part. What's the meaning of wheeled up words

Your question was answered on Stackexchange. I'm thinking "wheeled-up" means fancier and at a higher level of education, more erudite.
