To the Editor.—
In the June 22/29, 1984, issue of JAMA, you published an article entitled "Migration and Granulomatous Reaction After Periurethral Injection of Polytef (Teflon)." This is a misuse of Du Pont's trademark "Teflon.""Teflon" is Du Pont's trademark for several products, including fluorocarbon resins, films, and fibers. On the other hand, polytef is a generic term for pharmaceutical compositions of polytetrafluoroethylene and is not a product of the Du Pont Company as might be inferred from the title of this article. We sell no medical grades of "Teflon," and we do not endorse such uses. We have not performed the detailed, long-term studies that should be done before it is used for medical or surgical purposes.
