3. Boston Scientific
Boston Scientific, based in Natick, Massachusetts, is one of the largest pure-play medical device firms and has developed numerous devices for a variety of conditions including heart disease, heart attack, peripheral artery disease, asthma, atrial arrhythmia and others.
In the last five years, the company has reduced headcount by 1,800 positions taking overall employment to 23,000 as of 2013.
CORRECTION: The publishers of the report on which the slideshow is based - EvaluateMedTech - previously described these companies as firers. They have amended the report to reflect that headcount have been reduced in these companies. That could be because of workers being fired, but also sale of business units or other reasons that can cause headcount to shrink.
