a prospective, first in man study to evaluate the safety and performance of the novacross™ micro-catheter

Conditions: Chronic Total Occlusion of Coronary Artery

Summary: this is a prospective, non-randomized, first-in-man investigational study, to assess the safety and technical feasibility, deployment and withdrawal characteristics of the novacross™ micro-catheter during an interventional coronary angioplasty procedure and evaluating the cto penetration rate. each study subject/patient will have a total of one (1) procedure performed for this study.
