Patients with a CTO, defined as 99% to 100% stenosis of a peripheral artery, will be approached for enrollment in the study. Following providing informed consent, the CTO will be addressed by the Wildcat catheter, which will provide a route for the advancement of guidewires and other tools beyond the CTO. Data will be collected to assess the safety efficacy of use of the device during the procedure and up to 30 days post-procedure.
