An energy delivery device is disclosed. The energy delivery device may include 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. The energy emitting portion may be configured to transition between a first, collapsed configuration and a second, expanded configuration. In addition, the energy emitting portion may include a plurality of legs forming a basket, such that when the energy emitting portion is in the second, expanded configuration a central portion of at least one of the legs includes a substantially straight configuration.
