The medical system of claim 68 wherein each elongate member of the plurality of elongate members comprises a proximal end, a distal end, and an intermediate portion positioned between the proximal end and the distal end of the elongate member, wherein the intermediate portion of each elongate member of the plurality of elongate members comprises a front surface and a back surface opposite across a thickness of the elongate member from the front surface, wherein at least the intermediate portions of the elongate members of the plurality of elongate members are successively arranged front surface-toward-back surface in a stacked array comprising a plurality of successive pairs of the elongate members when the structure is in the delivery configuration, and wherein a respective particular group of the plurality of individually activatable transducer elements is arranged between the elongate members of each successive pair of the elongate members in the stacked array when the structure is in the delivery configuration. 76. The medical system of claim 68 wherein each elongate member of the plurality of elongate members comprises a proximal end, a distal end, and a respective length between the proximal end and the distal end of the elongate member, and the first axis passes through each of at least one elongate member of the plurality of elongate members when the structure is in the deployed configuration, the first axis passing through the one elongate member at two or more locations when the structure is in the deployed configuration, each location of the two or more locations spaced from another location of the two or more locations along the respective length of the one elongate member. 77. The medical system of claim 76 wherein the two or more locations comprise at least three locations spaced along the respective length of the one elongate member. 78. The medical system of claim 68 wherein each elongate member of the plurality of elongate members comprises a proximal end, a distal end, and a respective length between the proximal end and the distal end of the elongate member, and at least a first elongate member of the plurality of elongate members crosses a second elongate member of the plurality of elongate members in an X configuration at a particular location along the respective length of the second elongate member spaced from each of the proximal end and the distal end of the second elongate member when the structure is in the deployed configuration. 79. The medical system of claim 78 wherein the first axis passes through the particular location when the structure is in the deployed configuration. 80. The medical system of claim 68 wherein each elongate member of the at least two of the plurality of elongate members has a volute shape profile when the structure is in the deployed configuration. 81. The medical system of claim 68 wherein the shaft member comprises a surface at the second end of the shaft member, a portion of the surface circumferentially arranged about a second axis, and wherein the second axis is not parallel to the first axis when the structure is in the deployed configuration. 82. The medical system of claim 68 wherein the shaft member comprises a surface at the second end of the shaft member, a portion of the surface circumferentially arranged about a second axis, and wherein the second axis is not collinear with the first axis when the structure is in the deployed configuration.
