Business model failures? I don't think so. If ignorance is bliss - then you are 100% bliss. Complete success, produced the best salespeople and created a training model that almost every medical device company now uses, most of these other med device companies are led by USS personnel. Continued growth ina competitive space over 40 years, recognized leader in innovation.... thats just crazy talk (failure) USS developed stapling when it did not exist and then developed MIS surgery when it did not exist... created totally new markets...
