CardioFocus Completes Series C Financing

BOSTON, MASS - April 24, 2006 - CardioFocus, Inc., a privately held company focused on developing and commercializing catheter products for the treatment of atrial fibrillation (AFib), announced today it has raised a $21.5 million Series C round to propel the performance of a U.S. pivotal trial for its endoscopically-guided catheter ablation system. H.I.G. Ventures and KBL Healthcare Ventures led the $21.5 million round, joined by new investors Accuitive Medical Ventures and The Aurora Funds, as well as existing investors Oxford Bioscience Partners and SV Life Sciences.

"We are pleased to have attracted such an accomplished group of seasoned medical device investors,” said Stephen Sagon, Chief Executive Officer of CardioFocus. "As we move into this next phase of clinical trials, we will certainly benefit from their guidance and expertise in the field.”

Triggered by rapidly firing stimuli or premature beats arising from within the pulmonary veins, AFib is the most common cardiac arrhythmia affecting approximately 2.3 million people in the U.S. and 4.5 million people in the developed world. Patients suffering from AFib have a severely reduced quality of life and face significantly higher risk of stroke, heart failure and death. Drug treatment has been proven ineffective in as little as six months and in more than fifty percent of patients.

“The effective catheter treatment of AFib is one of the single biggest unmet needs in the field of cardiology, representing a $2 billion market opportunity,” said Dr. Bruce Robertson, Managing Director of H.I.G. Ventures. “CardioFocus has developed a novel device for treating this debilitating condition. The company’s management team has significant experience in the field of electrophysiology, and we believe their system will greatly improve the lives of those who suffer from AFib.”

CardioFocus’ patented endoscope, catheter and sheath technology uses adjustable arcs of light energy that can be optimally shaped and individually targeted to each vein’s anatomy. The CardioFocus catheter can visualize and isolate pulmonary veins, essential for the treatment of AFib, in a procedure expected to take less than two hours, unlike competitive RF energy procedures that can take up to six hours, even in the most experienced hands. To date, the company has successfully completed more than 20 patients of an ongoing feasibility study with excellent acute and chronic results. New abstracts on the company’s clinical progress will be presented at the annual meeting of the Heart Rhythm Society, May 17-20 in Boston.

“The CardioFocus ablation procedure promises superior efficacy and safety in comparison to competitive devices,” said Dr. Marlene Krauss, Managing Director and co-founder KBL Healthcare Ventures. “The integral endoscopic visualization gives a remarkable view of the area to be treated and, as a result, will enable a higher cure rate with fewer complications. In addition, the procedure is less complicated and time consuming, which will aid in the adoption by a broader spectrum of electrophysiologists.”

As a result of the financing, Bruce Robertson, PhD, Managing Director for H.I.G. Ventures, Marlene Krauss, MD, Managing Director and co-founder of KBL Heathcare Ventures, Chris Kroeger, MD, Principal for The Aurora Funds, and Charles Larsen, Managing Director for Accuitive Medical Ventures, will take seats on the CardioFocus board.
