The Medical Device sector has experienced some ups and down, as M&A goes. Last year, the sector posted 111 transactions and $85.6 billion in spending, which was an 8% and 620% improvement, respectively, over 2013’s performance. This year doesn’t look like a knock-out year for spending, with a sector total of just $36.2 billion as of November 20. Deal volume could still reach last year’s levels, since it stands at 103 deals as of that date.

Medtronic plc (NYSE: MDT) has been the busiest acquirer by far, with 10 deals announced. Seven of those disclosed prices, totaling $1.25 billion through November 20. Here’s our list of the top Medical Device deals to date.
