ABSTRACT:
Improved folding electrode assemblies and associated methods employ a structure comprising a wall peripherally enclosing an interior. The structure is adapted to selectively assume a geometry that changes between an expanded geometry having a first maximum diameter and a collapsed geometry having a second maximum diameter less than the first maximum diameter. At least one folding region in the wall is adapted to fold upon itself along a predefined fold line as the structure geometry changes. The folding region is formed when a portion of the wall is coated with an electrically conductive material for the purpose of transmitting electrical ablating energy, while another portion of the wall is left free of the electrically conductive material. Alternatively, the folding region is formed by forming an array of apertures in the wall.
