Now that the first half of 2011 is already in our rearview mirror, Medical Device Daily has compiled a Top 10 list of the biggest deals so far this year. Admittedly, the list was inspired by the excitement of last week’s dealmaking activity – Medtronic to spend a total of $645 million to buy Salient Surgical Technologies and PEAK Surgical and TPG Capital buying Immucor for $1.97 billion.

So without further ado, here are the Top 10 deals MDD has reported on so far this year, not including any deals that closed this year but were first disclosed last year.
