Aptus Endosystems, a biotech firm working on a device to fix abdominal aneurysms, just brought in $30 million in third-round funding to finish off clinical trials of its Abdominal Aortic Aneurysm Repair System, reports VentureWire. Heron Capital led the round, which also included Longitude Capital, Oakwood Medical Investors, Baird Venture Partners, FirstMark Capital, Prism VentureWorks and US Venture Partners.

The Sunnyvale, Calif. company says the round should be enough to cover the U.S. launch of the product in 2010 and a smaller release in Europe. Aptus last raised financing in 2006, bringing in $19.5 million to push the device through the first phases of trials.
