Leading the Way in Clinical Research 

researchimage3__contentimage@2x.png

Since its inception in 1983, CIS has been at the forefront of interventional cardiovascular research, earning international acclaim through participation in a growing number of research trials. CIS physicians serve as clinical investigators in these trials to research many new and innovative medical devices for patients. Additionally, CIS physicians share their knowledge of new devices by lecturing around the world about the latest methods of treating both cardiac and peripheral arterial disease. 

Our devotion is to advance patient care through innovative technology. As a leader of research and development, we are proud to currently offer more than 30 available research trials, including those listed below.
