Claim:
1. A medical system comprising: a structure sized to be received in a bodily chamber, the structure selectively moveable between a delivery configuration and an expanded configuration, a portion of the structure having a respective size and dimension greater in magnitude in the expanded configuration than in the delivery configuration; and a plurality of flexible printed circuit strips moveable with the structure between the delivery configuration and the expanded configuration, each flexible printed circuit strip of the plurality of flexible printed circuit strips comprising an electrically conductive trace, a flexible electrically insulative substrate, and a transducer element electrically connected to the electrically conductive trace, at least a portion of the transducer element located on an outward-facing surface of the flexible electrically insulative substrate, at least a portion of the outward-facing surface positionable to face away from an interior of the bodily chamber toward a tissue surface of a wall of the bodily chamber at least when the structure is in the expanded configuration inside the bodily chamber, wherein, at least when the structure is in the expanded configuration, a first portion of the outward-facing surface of the flexible electrically insulative substrate of a first flexible printed circuit strip of the plurality of flexible printed circuit strips and a first portion of the outward-facing surface of the flexible electrically insulative substrate of a second flexible printed circuit strip of the plurality of flexible printed circuit strips face a same first direction, with the first portion of the outward-facing surface of the flexible electrically insulative substrate of the first flexible printed circuit strip crossing behind the first portion of the outward-facing surface of the flexible electrically insulative substrate of the second flexible printed circuit strip when the first portion of the outward-facing surface of the flexible electrically insulative substrate of the second flexible printed circuit strip is viewed from a direction opposite the same first direction, wherein, at least when the structure is in the expanded configuration, a second portion of the outward-facing surface of the flexible electrically insulative substrate of the first flexible printed circuit strip of the plurality of flexible printed circuit strips and a first portion of the outward-facing surface of the flexible electrically insulative substrate of a third flexible printed circuit strip of the plurality of flexible printed circuit strips face a same second direction, with the second portion of the outward-facing surface of the flexible electrically insulative substrate of the first flexible printed circuit strip crossing behind the first portion of the outward-facing surface of the flexible electrically insulative substrate of the third flexible printed circuit strip when the first portion of the outward-facing surface of the flexible electrically insulative substrate of the third flexible printed circuit strip is viewed from a direction opposite the same second direction, and wherein the first portion of the outward-facing surface of the flexible electrically insulative substrate of the second flexible circuit strip and the first portion of the outward-facing surface of the flexible electrically insulative substrate of the third flexible circuit strip are adjacent at least when the structure is in the expanded configuration.
