He has submitted his resignation and will effective at the end of March. I can guarantee this is not a fun job right now with the recalls and all the issues the DePuy division has faced. He’s an executive in charge of running a failing implant 
division, and personally he did not create the units, nor did he implant any of them but it’s his bowl of wax, well at least until the end of the month. Sometimes when in positions as such with recalls and failures, you might wonder does anyone really want that job? I wouldn’t as you are not going to be able to please very many people and opinions at all. In the meantime if one company can’t make an implant that works, maybe go buy another, at least that is what it looks like with recent news.
