Cardiovascular Systems, Inc. Announces Recommendation For ISO Certification

MINNEAPOLIS, Feb. 23 /PRNewswire/ -- Cardiovascular Systems, Inc. (CSI), today announced that it has received recommendation for ISO 13485:2003 registration of its quality management system. The recommendation was issued following an initial quality management system assessment visit by our notified body BSI, Inc. This recommendation represents an important step towards receiving authorization to affix the CE Mark of conformity, allowing European commercialization.

Michael J. Kallok, CEO of Cardiovascular Systems, Inc. said, “We are pleased to announce that our quality management system has been recommended for ISO quality system registration. Our product development and manufacturing teams deserve credit for this accomplishment in such a short period of time.”

The Orbital Atherectomy Device utilizes a diamond coated, eccentrically rotating cutting surface to ablate tissue. The Company believes the resulting particles are small enough to pass through capillaries and be eliminated by the body. The Company is working on obtaining FDA clearance for use of the device in peripheral vascular disease, and approval for use in coronary arteries.

The Company has previously announced it had received marketing clearance from the U.S. Food & Drug Administration (FDA). The FDA 510(k) cleared-to- market the Company’s Orbital Atherectomy System to remove tissue causing stenosis in synthetic A-V shunts. The Company expects to conduct initial market testing at a limited number of clinical sites before having a full commercial release of the product for treating AV shunts.

Cardiovascular Systems, Inc. is a medical device development company which has designed, developed, and is testing its Orbital Atherectomy Device for removal of atherosclerotic blockages in coronary and peripheral arteries. The Company’s proprietary technology is protected by 22 issued US patents and several other pending patents.
