Claim Text:
1. A medical system comprising: a plurality of individually activatable transducer elements; a structure comprising a plurality of elongate members, each elongate member of the plurality of elongate members comprising a respective proximal end, a respective distal end, and a respective intermediate portion positioned between the respective proximal end and the respective distal end of the elongate member, the structure selectively moveable between an unexpanded configuration in which the structure is sized to be percutaneously delivered to a bodily cavity and an expanded configuration in which the structure has a size too large to be percutaneously delivered to the bodily cavity, each of the respective intermediate portions of the plurality of elongate members circumferentially arranged with respect to one another about a first axis when the structure is in the expanded configuration, and each of the respective intermediate portions of the plurality of elongate members radially spaced from the first axis when the structure is in the expanded configuration, each elongate member of at least a set of the plurality of elongate members comprising a respective group of the plurality of individually activatable transducer elements; a flexible shaft member, a portion of the flexible shaft member sized to be percutaneously delivered to the bodily cavity, the flexible shaft member comprising a first end portion and a second end portion spaced from the first end portion across an elongated portion of the flexible shaft member, the structure physically coupled to the flexible shaft member at least proximate the second end portion of the flexible shaft member; and at least one actuator selectively operable to concurrently rotate the intermediate portions of all of the plurality of elongate members at least partially about at least the first axis when the structure is in the expanded configuration, the intermediate portions of all of the plurality of elongate members moved relative to at least the second end portion of the flexible shaft member by the at least one actuator when the structure is in the expanded configuration, wherein the second end portion of the flexible shaft member comprises a surface, a portion of the surface positioned at an end of the flexible shaft member, the portion of the surface circumferentially arranged about a second axis, and wherein, when the structure is in the expanded configuration, the intermediate portions of the plurality of elongate members are positioned to avoid circumferential arrangement about the second axis.
