There is something rather strange about this. Earlier this year, there was an assassination attempt on the King of Saudi Arabia. The suicide bomber carried the bomb internally, but it wasn't surgically implanted. I'll leave you to fill in the blanks.
There is, in other words, not very good reason to assume that 'sensitivity from recent surgery' will accomplish much.
