Ummm...clearly you are referring to another division of Cook, and not Surgery. Many other divisions of Cook, PI, IR, Urology, are almost exclusively driven by contracts, but not Surgery. Surgery is the exact opposite of a commodity product. 100% physician preference. If the rep doesn't show up for almost every case in the first few months, physician does not use the product. Not on a single GPO contract, and nearly every new customer is soley gained because a rep spent a couple months working with the surgeon to try Biodesign.
