May 8, 2008 -- San Diego and Brussels, Belgium -- Volcano Corporation (Nasdaq: VOLC), a leading manufacturer and developer of intravascular ultrasound (IVUS), functional measurement (FM) and Optical Coherence Tomography (OCT) products designed to enhance the diagnosis and treatment of coronary and peripheral vascular disease, announced today the first human procedure using the Volcano OCT Imaging catheter. The procedure was performed by Dr. Patrick Serruys at the Thoraxcenter, in Rotterdam, Netherlands. Volcano OCT will complement its existing line of IVUS imaging catheters and pressure guidewires used for coronary imaging and lesion assessment.

Volcano acquired the OCT technology through its purchase of CardioSpectra at the end of 2007.

Scott Huennekens, President and Chief Executive Officer of Volcano, commented, "Volcano is committed to being the leader in intravascular imaging, both to complement everyday PCI technique, and to further the understanding of atherosclerotic disease progression. Our investment in this OCT product line underscores that commitment, and opens a series of new clinical applications and opportunities to complement our existing product line. We are delighted to be underway with our OCT effort just four months after completing the acquisition.

"With our two imaging technologies, we are the leader in intravascular imaging and commercializing this technology will provide us further competitive advantages. We are working on offerings that incorporate OCT functionality into our s5i IVUS platform, as well as standalone OCT systems. Our emphasis continues to be focused around 'Choice', the ability for Volcano to provide a number of different therapy enabling modalities, and letting the physician choose which technology is appropriate for each individual patient."

Christopher E. Banas, Vice President and General Manager of Volcano's OCT Division in San Antonio Texas, and former CEO and Chairman of CardioSpectra commented, "This is an important step in demonstrating the ability of Volcano's OCT catheter to safely image coronary vessels of human patients and establishing a leadership position in advanced coronary imaging technologies."

Volcano's OCT imaging platform provides high-resolution images in the 10- 15 micron range, opening the door for new applications to complement both IVUS and angiography. Michel Lussier, president of Volcano Europe commented, "The high resolution OCT images provide a glimpse at structural detail not seen before by other imaging modalities. We believe that OCT has the potential to identify thin-cap fibro-atheromas, clearly highlight intraluminal thrombus, and assess the complete healing of novel drug-eluting stent designs. Volcano is committed to exploring the various clinical benefits of our OCT platform through detailed data-driven study design and mutually beneficial partnerships with other therapy companies."

Patrick W. Serruys, M.D., PhD, commented:

"The Volcano OCT Imaging Catheter is another step closer to delivering interventionalists with the true cath lab of the future. To better serve my patients, I want the flexibility to select from an array of different tools, quickly interrogate the vessel, and immediately process the information.

"Having these various technologies, including IVUS, OCT and FFR, all integrated into the lab, with a common user interface, review points, data storage and staff training provides this flexibility."
