CardioMems, a medical device firm developing wireless devices that can be implanted for management of cardiovascular disease, has closed on $22 million in new financing.
The company intends to raise $29.5 million, according to a filing with the Securities Exchanged Commission.
CardioMems has already raised more than $80 in five earlier rounds.
In 2007, CardioMems raised $33 million in a Series E round. Investors included Arcapita Ventures, Boston Millennia Partners, Medtronic, Inc., Easton Capital Partners, Foundation Medical Partners, and Arboretum Ventures, along with new investors Deerfield Capital Management, Vision Capital Advisors, Aperture Venture Partners and Rockport Venture Securities.
CardioMems had disclosed plans to go public in January 2007 but the company withdrew the IPO that summer. It had planned to raise $87 million in the offering.
