Claim 24:
25. A catheter device system comprising:
an elongated catheter member including a proximal end portion, a distal end portion comprising a distal end, and an elongated portion between the distal end portion of the elongated catheter member and the proximal end portion of the elongated catheter member, the elongated portion located along a length of the elongated catheter member, the elongated catheter member selectively moveable between:
a delivery configuration in which at least the distal end portion of the elongated catheter member is sized to be percutaneously deliverable to a bodily cavity, the elongated catheter member configured to cause the distal end portion of the elongated catheter member to be deliverable ahead of the elongated portion of the elongated catheter member to the bodily cavity in a state in which the elongated catheter member is in the delivery configuration, and
a deployed configuration in which at least the distal end portion of the elongated catheter member is sized too large to be percutaneously deliverable to the bodily cavity; and

a plurality of electrodes positionable in the bodily cavity, each electrode of the plurality of electrodes comprising a respective external energy transmission surface,
wherein each electrode of at least one electrode of the plurality of electrodes is configured to selectively transmit energy from the external energy transmission surface of the electrode, the energy sufficient to ablate tissue,
wherein, in a state in which the elongated catheter member is in the deployed configuration, the distal end portion of the elongated catheter member comprises (a) a first portion bending away from the elongated portion of the elongated catheter member, and (b) a loop-shaped second portion positioned along the length of the elongated catheter member closer toward the distal end of the distal end portion of the elongated catheter member than the first portion of the distal end portion of the elongated catheter member, the plurality of electrodes located on the loop-shaped second portion of the distal end portion of the elongated catheter member,
wherein, in the state in which the elongated catheter member is in the deployed configuration, a first portion of the loop-shaped second portion of the distal end portion of the elongated catheter member is in an at least partially overlapping relationship with a second portion of the loop-shaped second portion of the distal end portion of the elongated catheter member,
wherein the plurality of electrodes comprises a first electrode and a second electrode, the external energy transmission surface of the first electrode having a different size, shape, or both size and shape than the corresponding external energy transmission surface of the second electrode, such that the plurality of electrodes include external energy transmission surfaces having different sizes, shapes, or both sizes and shapes, and
wherein the different size, shape, or both size and shape of the external energy transmission surface of the first electrode compared to the corresponding external energy transmission surface of the second electrode is or are configured to accommodate the at least partially overlapping relationship between the first portion of the loop-shaped second portion of the distal end portion of the elongated catheter member and the second portion of the loop-shaped second portion of the distal end portion of the elongated catheter member.
