Abstract: According to one aspect, a medical system may include an instrument including an end effector for acting as a monopolar electrode. The end effector may be configured to be positioned in a body of a subject and emit radiofrequency energy towards a target area in the body. The medical system may further include a return electrode. The return electrode may be deliverable within the body proximate the target area and separately from the instrument and the monopolar electrode. The return electrode may be configured to contact tissue in the body proximate the target area and receive radiofrequency energy emitted from the end effector.

Abstract: According to one aspect, an instrument may include a sheath having a distal end. The instrument also may include a fluid cannula at the distal end of the sheath. The instrument also may include a cutting electrode at the distal end of the sheath. At least one of: (i) an exterior surface of the fluid cannula, and (ii) a cutting electrode surface that faces the exterior surface, is longitudinally slidable along the other of the exterior surface and the cutting electrode surface during movement of at least one of the cutting electrode and the fluid cannula relative to the other of the cutting electrode and the fluid cannula.
