Expandable-collapsible mesh electrode structures
 Collapsible electrode assemblies and associated methods employ an array of filaments assembled to form a mesh structure. The mesh structure is adapted to selectively assume an expanded geometry having a first maximum diameter and a collapsed geometry having a second maximum diameter less than the first maximum diameter. Preferably, at least one of the filaments includes an electrically conductive material adapted for coupling to a source of ablation energy for transmitting ablation energy.
