Claim:
1. An energy delivery device, comprising: an elongate member having a proximal end and a distal end; and an energy emitting portion coupled to the distal end of the elongate member, wherein the energy emitting portion is configured to transition between a first, collapsed configuration and a second, expanded configuration; wherein the energy emitting portion includes a plurality of legs forming a basket, wherein a central longitudinal axis passes through a radial center of the basket, and wherein, when the energy emitting portion is in the second, expanded configuration, a central portion of at least one of the plurality of legs includes (a) a first substantially straight section that is positioned at a first distance from the central longitudinal axis when in the second, expanded configuration, and (b) a second substantially straight section that is positioned at a second distance from the central longitudinal axis when in the second, expanded configuration, wherein the first distance and the second distance are different, wherein the central portion of the at least one leg further includes a connecting portion that extends proximally from a distal end of the first substantially straight section to a proximal end of the second substantially straight section, and wherein the first substantially straight section and the second substantially straight section are spaced apart from one another by a third distance in the first, collapsed configuration, and by a fourth distance in the second, expanded configuration, wherein the fourth distance is larger than the third distance.
