                    Diego -- Volcano Corporation (Nasdaq: VOLC), a leading
                    developer and manufacturer of precision intravascular therapy
                    guidance tools
                  designed to enhance the diagnosis and treatment of coronary
                    and peripheral vascular disease, announced today that it
                    has entered
                  into a distribution agreement with AngioScore for its AngioSculpt® PTCA
                  Scoring Balloon Catheter for coronary indications in Japan.
                   This is the first of what Volcano believes will be many products
                    distributed
                    by Volcano Japan, which now includes more than 50 direct
              sales representatives.  |  "Not every lesion or heart blockage is the same," commented Scott Huennekens, President and CEO of Volcano. "Physicians
              have to make a number of difficult decisions as they build a lesion
              by lesion treatment strategy for their patients. The first step
              is to identify which blockages require angioplasty or stenting,
              or a combination of both, versus medical therapy alone. But once
              the decision has been made to place a stent, the pre-stent preparation,
              and the post-stent expansion strategies can differ greatly across
              lesion types as well. This relationship between Volcano and AngioScore
              now combines two technologies: Visualization with Volcano's intravascular
              imaging products to build a lesion specific strategy; and tailored
              therapy with the AngioSculpt Scoring Balloon Catheter to deliver
              a targeted treatment for that specific type of lesion. This concept
              of precision-guided therapy using intravascular imaging has already
              taken hold in Japan where the technique is used in more than 70%
              of all PCI procedures. Our distribution of the AngioSculpt device
              now gives us access to both parts of the equation - imaging and
              therapy."           The AngioSculpt Scoring Balloon Catheter represents the next generation in angioplasty catheters. Its innovative nitinol element provides unique anti-slipping properties while circumferentially dilating plaque, providing a precise and predictable dilatation across a wide range of lesion types. The AngioSculpt provides the versatility and effectiveness of a new technology together with the simplicity and deliverability of a high-performance balloon catheter.
           "We are excited about teaming with Volcano, particularly with the Volcano Japan sales organization," stated Thomas Trotter, President and CEO of AngioScore. "Over
              the past 18 months, Volcano has built one of the largest direct
              sales organizations in Japan of any company developing intravascular
              imaging devices. Importantly, Volcano's leadership in education
              related to disease progression, and their valued presence in the
              cath lab, will help make the most of their product portfolio, which
              now includes the AngioSculpt PTCA Scoring Balloon Catheter."
           The exclusive, five-year distribution agreement became effective April 1, 2010. Volcano will distribute the entire line of AngioSculpt PTCA Scoring Balloon Catheters and any new, modified or next generation PTCA products.
           "Angiography alone is not enough, and Volcano has a broad distribution platform to support that message," added Huennekens. "Building
              our direct sales organization in Japan has been a successful strategic
              initiative over the past 18 months, as our team now includes more
              than 50 direct sales representatives, who are in the field calling
              on cath labs every day. Our sales channel, complete with seasoned
              clinical and regulatory personnel, is well-positioned to bring
              to market our pipeline of new products and complementary distributed
              products. We suspect that other companies developing interventional
              cardiology devices for the Japanese market will not only see the
              value in our precision guidance tools, but will also consider Volcano
              as a very viable option for distribution of their products."
