hospitals don't care about coatings that really have no proof, purchasing makes the decision and rebates and market share drives the decisions. Unfortunately for the competition, Bard has the market share and has some technology that is proprietary, they have effectively locked out much of the competition. It's also why they don't need to pay tons of money to their reps, just need to maintain things and keep the pressure on the reps to load the shelves.
Cost of change is high, so easier to collect the rebate/bribe - Angio D has no market share and no great products and not enough reps
