METHOD AND APPARATUS FOR ABLATIVE RECANALIZATION OF BLOCKED VASCULATURE

摘要

A method of treating vessel occlusions including chronic total occlusions (CTO) of the coronary arteries, and to generally remove tissue material, is presented that relies on remotely actuated navigation of an interventional RF-capable ablation device to the occlusion and controlled application of ablative RP energy. The combined use of remote navigation-based precision control of the distal end of the device and application of ablative energy enables crossing of elongated lesions and CTOs, calcified lesions and CTO's, lesions and CTO's located at vessel branches, and in general the removal of tissue material at a chosen tissue location.
