1. A medical device, comprising:

  • a basket assembly configured to transition between a collapsed state and an expanded state, a central longitudinal axis extending through a radial center of the basket assembly, wherein the basket assembly includes a plurality of expandable legs, and a first expandable leg of the plurality of expandable legs includes an active region, wherein;

    the first expandable leg is pre-shaped such that in the collapsed state and while the basket assembly is unconstrained by an outer sheath, the active region is convex when viewed from the central longitudinal axis;

    the active region is configured to contact and deliver energy to tissue when the basket assembly is in the expanded state; and

    when the basket assembly is in the expanded state, distal ends of the plurality of expandable legs converge toward one another.
