AngioDynamics Reports Fiscal 2014 First Quarter Financial Results

ALBANY, N.Y., (October 10, 2013) - AngioDynamics (NASDAQ: ANGO), a leading provider of innovative, minimally invasive medical devices for vascular access, surgery, peripheral vascular disease and oncology, today reported financial results for the fiscal 2014 first quarter ended August 31, 2013.

"Our growth drivers performed at, or above, our expectations in the first quarter, demonstrating the value in our strategic initiatives and ability to expand market opportunities for our products," said Joseph M. DeVivo, President and Chief Executive Office. "Our sales team is approaching the market with solutions, including our AngioVac cannula and circuit, and growing BioFlo portfolio, that are valued by the healthcare industry not only for their potential to improve patient outcomes, but also for reducing overall treatment costs. Early data following the commercialization of our BioFlo PICCs has shown the capability to dramatically reduce PICC-related upper extremity deep vein thrombosis - a problem that is estimated to cost hospitals more than $1 billion annually. The market's response and product results are encouraging, and coupled with other positive developments, supports our expectation of accelerated growth commencing in the fiscal 2014 second half."
