How exactly would this work? Station someone on the sidewalk outside the hospital and interview people leaving the building? "Excuse me sir, have you received a medical implant today? We're interested in enrolling you in our study group which will take a good deal of your time and give you no benefit..."

More systematically: offer a "good housekeeping" seal. Presumably those who have good implants will cooperate and open their books so you can look at who they install to and outcomes. Being a reliable 3rd party, cooperating and getting a gold medal seal will help with sales.

1) For current patients, how will you get their data. I'm reluctant to give some places my email address; access to my complete medical records for the rest of my life is a giant stretch.

2) For future patients (or their doctors), how will you convince them that your recommendation is credible and not some kind of front for a specific manufacturer?
