Chronic Total Occlusions (CTOs) are a leading cause of amputation and the most common reason patients are sent to surgery. Effective revascularization of CTOs begins with successful crossing. However, this process can be complex and frustrating. In fact, 20% to 30%1-4 of CTOs cannot be crossed with a guidewire and support catheter alone. Having the right tools on hand to meet any crossing challenge is essential to success. Spectranetics offers a complete portfolio of products that enable you to safely and efficiently cross CTOs, and only Spectranetics offers a written guarantee.
