1. A mapping and coagulation apparatus, comprising:
- a tissue coagulation probe including a tissue coagulation probe support body defining at least one interior lumen, and an inflatable tissue coagulation structure supported on the tissue coagulation probe support body; and
a mapping probe passable through the tissue coagulation probe support body lumen including a mapping probe support body, and an expandable/collapsible mapping basket supported on the mapping probe support body.

Abstract
A probe that may be used to create circumferential lesions in body tissue and, in some implementations, may also be used to perform mapping functions. The probe includes a collapsible/expandable structure that supports electrodes or other operative elements against the body tissue.
