The medical device tax, which will collect $20 billion from device makers over 10 years, is set to go into effect Jan. 1, 2013 and some companies are beginning to enumerate how much it will cost them.

He enlisted a colleague to call all 400 signatories of the letter written by the Medical Device Manufacturers Association that was sent to Congress to urge the repeal of the device tax.
