The president of Bloomington-based Cook Medical says despite "considerable disappointment" that the fiscal cliff deal did not include a delay in a new medical device tax, the company will continue efforts to lobby lawmakers and the public. Kem Hawkins says the tax will cost Cook $20 million this year and slow down the development of new products. The company has halted U.S. expansion because of the tax. Hawkins believes small companies will take the biggest hit.
