Cardiovascular Systems CEO to Take Medical Leave

Cardiovascular Systems (CSI) (CSII) said today that, effective Dec. 1, 2015, Chief Executive Officer David L. Martin will take a medical leave of absence for approximately three months to focus on his cancer treatment. While Martin is on leave, Scott Ward, currently Chairman of the Board of Directors, will serve as Chairman and Interim Chief Executive Officer.

CSI announced on September 14, 2015, that Martin is undergoing treatment for stomach cancer. At this point in his treatment regimen, he will undergo surgery, followed by additional chemotherapy.

Martin said, "Scott's extensive experience in medical technology and role as CSI Chairman make him an excellent selection for interim Chief Executive Officer. With Scott and our executive management team's leadership, I can concentrate on my remaining treatment and recovery. This cancer can be cured, and I plan to return as CEO in March 2016."

Ward became a member of CSI's Board of Directors in 2013 and was named Chairman in November, 2014. He is a Managing Director at SightLine Partners and the President of Raymond Holdings, positions that he will continue to hold. From 1981 to 2010, Ward was employed by Medtronic, Inc. and held a number of senior leadership positions including Senior Vice President and President of Medtronic's CardioVascular business from May 2007 to November 2010.

Said Ward, "Dave has the full support of CSI and its Board as he completes his treatment. We wish him a quick recovery and look forward to his return. CSI is a remarkable company with a strong mission to improve the quality of care for patients with coronary and peripheral artery disease. I look forward to working with the CSI team to advance the company as a leader in the treatment of calcified artery disease."
