San Diego-based CardioNet, which makes wireless mobile cardiac outpatient monitoring solutions, announced today that it closed $110 million in private financing. The company’s chairman and CEO, James Sweeney, says the $110 million is one of the largest private placements of equity bridge financing in the med tech sector since January 2000. CitiGroup Global Markets served as the lead placement agent for the financing, and Sun Trust Robinson Humphrey served as co-placement agent. The announcement comes a couple weeks after CardioNet completed its acquisition of cardiac event-monitoring company PDSHeart for an undisclosed sum. Full release.
