Cardiovascular

Cardiovascular Systems, Inc. (CSI) is a medical device company focused on developing and commercializing innovative solutions for treating vascular and coronary disease. The company's primary technology is the Orbital Atherectomy System (OAS), which is designed to treat calcified plaque in both peripheral and coronary arteries. By utilizing a diamond-coated crown that rotates at high speeds, the system creates a centrifugal force to sand away hard plaque while remaining safe for healthy arterial tissue. CSI's product portfolio includes the Diamondback 360 and Stealth 360 systems, which are widely used by interventional cardiologists and vascular surgeons. In 2023, the company was acquired by Abbott Laboratories, integrating its atherectomy technology into Abbott's broader vascular portfolio.
