摘要： Collapsible electrode assemblies and associated methods employing a structure having an axis and a distal end. The structure comprises a wall peripherally enclosing an interior. The structure is adapted to selectively assume an expanded geometry having a first maximum diameter about the axis and a collapsed geometry having a second maximum diameter about the axis less than the first maximum diameter. An electrically conductive material is carried by the wall, forming an electrode region adapted to conform to both the normally expanded geometry and the collapsed geometry of the structure. In one implementation, a flexing element in the interior of the structure bends within the interior along the axis of the structure to displace the distal end relative to the axis. In another implementation, a stilette element within the interior of the structure imparts axial force upon the distal end along the axis of the structure, thereby axially elongating or shortening the structure.

The electrode assembly includes a wall comprising an electrically conductive material peripherally surrounding an interior area. The wall has an interior surface facing the interior area and an oppositely facing exterior surface. A first element operatively associated with the exterior surface of the wall is adapted to carry out a first predetermined electrical transmitting or sensing function affecting body tissue. A second element operatively associated with the interior surface of the wall is adapted to carry out, independent of the first element, a second predetermined electrical transmitting or sensing function affecting body tissue different than the first predetermined electrical function.
