MASSDEVICE ON CALL — Implantable defibrillators, coronary artery disease tests and implantable obesity treatment devices got the most venture capital attention in the first half of 2011, topping a list of the 10 biggest VC deals so far this year.

Coming in at number one, Cameron Health rounded up $107 million from Alloy Ventures and Delphi Ventures for its landmark completely subcutaneous  implantable defibrillator, which has yet to win FDA clearance.

Following far behind in second was Intrapace Inc., which rounded up $60.9 million from InCube Ventures, L Capital Partners, and Oxford Bioscience Partners for its implantable obesity treatment system. The company won CE Mark approval in the European Union for a new wireless monitoring feature for the device earlier this month.

In third, CardioDx raised $60 million for its blood-based gene expression test for obstructive coronary artery disease.
