Hi 33333 and Pat Fill,
I too, have been reading Dr. Louie's blog and HW (of course!) and I am beginning to think that waiting for more hard data (in my case) as to the success of the Linx might be prudent since the device is so new.
IMO, I was a bit thrown by the problem with the Linx sizing tool, mentioned by 33333 and that the Linx is not sutured at the closed end of the loop to a solid tissue foundation to ensure that it does not slide up or down.
My other concern (according to Dr. Louie's post to 33333) is that the Linx might rub against the Vagus nerve.
