VisEn Medical Announces $4M Venture Capital Financing

August 15, 2005

CAMBRIDGE, Mass., Aug. 15 /PRNewswire/ -- VisEn Medical, a pioneer in the field of optical molecular imaging, today announced that it has raised $4 million of additional venture capital financing. The round was led by Flagship Ventures and included follow-on investments by Bollard Group and other existing investors. VisEn intends to use the proceeds to support the commercial launch of its initial products later this year, and to develop additional applications of its technologies. The Company also announced that Ed Kania, Managing Partner and Chairman of Flagship Ventures, has joined its board of directors.

"In the first half of 2005, we conducted a very successful pre-launch program, selling a pre-commercial version of our tomographic optical imaging system to three top-tier pharmaceutical companies and two leading academic institutions in the United States and in Europe. These five sites and about 20 additional pharmaceutical and academic customers have begun to purchase our line of molecular imaging probes," said Kirtland G. Poss, President and CEO. "We are now positioned to launch the commercial version of our imaging system and to expand the sales and marketing of our probes later this year. We also will continue to work closely with our customers and partners to develop additional applications and products based on our powerful core technologies and competencies," he continued.

VisEn's core technology platforms are designed to harness the power of optical imaging in vivo. The Company's Fluorescent Molecular Tomography ("FMT") system and optical probe portfolio use near infrared light to produce quantifiable molecular maps of disease activities deep within the body. Going beyond other imaging modalities such as CT, MRI and X-ray, VisEn's FMT system and optical probe portfolio can detect not only anatomic structures, but also biological processes at the molecular level, providing earlier, more sensitive, quantifiable measures of disease progression and therapeutic efficacy in vivo. Specifically, the FMT system enables unprecedented depth penetration and quantification of optical molecular imaging signals in vivo, and the probe portfolio enables a wide range of powerful imaging applications in disease areas including oncology, inflammation and cardiovascular disease. While VisEn's initial products are intended for small animal imaging applications used in research and preclinical studies, these same technologies will be extended over time to pharmaceutical development and clinical medicine.

"VisEn Medical is pioneering a new era in molecular imaging," said Ed Kania, Managing Partner and Chairman of Flagship Ventures. "Its products have immediate applications in a wide range of research areas, and a substantially larger future market opportunity as the technology is directly translatable to human medicine. We are pleased to have joined VisEn's team and existing investors in supporting the Company's transition to commercialization of its technology," he added.
