Here's an example from the Wichita Eagle posted on Sept. 6: Robot surgery now offered for head, neck procedures
The part of the article that ping'd my search radar was this:
"The da Vinci surgical system is now approved for use in surgeries of the head and neck."Search for the missing information. Who approved it and when?
This search requires a keyword query, browsing, a deep web query of a specialized database and careful reading.
Post your answers in the comments: Who approved the device (I left a clue in this post) and (here's the real challenge) WHEN was approval granted? Provide an official date.
What problems do you encounter in this search?
