1. A medical device system comprising:
a plurality of transducer sets, each transducer set comprising one or more transducers positionable in a bodily cavity;
a plurality of elongate members, at least parts of the elongate members collectively forming a structure on which the plurality of transducer sets are located, each elongate member comprising at least a particular portion on which no transducer selectively operable to transmit energy is located; and
a shaft member physically coupled to the plurality of elongate members, a location at which the shaft member is physically coupled to each elongate member of the plurality of elongate members is fixed with respect to a shaft distal end of the shaft member, the shaft member configured to percutaneously deliver the structure to the bodily cavity at least in response to translation of at least part of the shaft member, and the shaft member comprising a shaft proximal end, the shaft distal end, and an elongated portion extending between the shaft proximal end and the shaft distal end,
wherein the structure is selectively moveable between:
a delivery configuration in which the structure is sized to be percutaneously deliverable to the bodily cavity, each of the plurality of elongate members comprising a helical configuration of the particular portion, the helical configuration including at least 360 degrees of rotation when the structure is in the delivery configuration, and
a deployed configuration in which the structure is sized too large to be percutaneously deliverable to the bodily cavity,
wherein, for each particular elongate member of the plurality of elongate members, the particular elongate member comprises a flexible circuit structure extending between a proximal portion of the particular elongate member and a distal end of the particular elongate member, the flexible circuit structure comprising the particular portion of the particular elongate member, and the flexible circuit structure comprising a conductive layer patterned on an electrically insulative layer, and
wherein the particular portion of each elongate member of the plurality of elongate members is located within the elongated portion of the shaft member.
