摘要： A method of treating vessel occlusions including chronic total occlusions (CTO) of the coronary arteries is presented that relies on remote navigation of a remotely steered medical device to the occlusion and controlled application of ablative energy or mechanical push together with real-time local imaging of the vasculature or real-time vessel wall sensing. The combinative use of remote navigation methods and real-time imaging or real-time sensing enables crossing of elongated lesions and CTOs, calcified lesions and CTOs and lesions and CTOs located at vessel branches.
