In a letter dated last month, and obtained by the Politico Web site, 12 members of Congress ask FDA Commissioner Margaret A. Hamburg, MD, for some specific changes, including a "more detailed work schedule for implementing recommendations," more details on the proposed changes to the 510(k) medical device clearance process, as well as time for "adequate and appropriate public comment."

The Congressmen note that "without knowing greater specifics of each proposal, it is difficult to adequately assess their full impact."

Signing the letter were Reps Baron Hill (D-Ind), Jim Matheson (D-Utah), John Barrow (D-La), Christopher Murphy (D-Conn), Zach Space (D-Ohio), Jerry McNerney (D-Calif), Joe Barton (R-Tex), Fred Upton (R-Mich), John Shimkus (R-Ill), Joseph Pitts (R-Pa), Mike Rogers (R-Mich), and Michael Burgess (R-Tex).
