摘要

A probe assembly for ablating tissue around a vessel ostium, including an outer probe including an elongate probe body having a distal ablative structure, a lumen having an exit port, and one or more ablative elements mounted to the distal ablative structure; and an inner probe configured to be slidably disposed within the lumen of the outer probe, the inner probe including an elongate probe body having a distal diagnostic structure configured to extend out the exit port, and one or more diagnostic elements mounted to the distal diagnostic structure.
