1. A medical system comprising:
an instrument including a performing electrode at a distal end of the instrument, wherein the distal end of the instrument is configured to be positioned in a body of a subject and the performing electrode is configured to emit radiofrequency energy towards a target area in the body; and
a return electrode deliverable within the body proximate the target area, separately from the instrument and external to the instrument, wherein the return electrode is configured to be separately movable relative to the instrument, contact tissue in the body proximate the target area, and receive radiofrequency energy emitted from the performing electrode, wherein the return electrode includes a central lumen configured to receive the target area.
