MEDICAL PROBES FOR CREATING AND DIAGNOSING CIRCUMFERENTIAL LESIONS WITHIN OR AROUND THE OSTIUM OF A VESSEL
First Claim
1. A probe for ablating tissue, comprising:
- an outer elongate probe body including a distal ablative structure having an open architecture defining an interior space;
a lumen extending through the outer probe body, the lumen configured to slidably receive an inner elongate probe body, the lumen having an exit port out which the inner probe body can extend within the interior space; and
one or more ablative elements mounted to the distal ablative structure, wherein the one or more ablative elements are arranged to create a circumferential lesion.

Abstract
The present inventions provide assemblies, probes, and methods for creating circumferential lesions in tissue, e.g., the tissue within or around the ostium of a vessel. An ablation probe with an ablative structure can be placed in contact within or around the ostium of the vessel. A diagnostic probe can be introduced through a lumen within the ablation probe and inserted into the vessel. The energy can be provided to the ablative structure to create a circumferential lesion within or around the ostium of the vessel, and the diagnostic structure can be used to diagnose the tissue to determine whether the circumferential lesion can be properly created.
