1. An apparatus to treat tissue at a surgical site of a patient, the apparatus comprising:
an elongate carrier comprising a nozzle configured to emit a fluid stream, the elongate carrier comprising a longitudinal axis; and
a probe configured for insertion into a patient, the probe comprising an evacuation lumen to remove material from the surgical site, the evacuation lumen extending to an opening; wherein the fluid stream comprises a jet, and wherein the opening comprises a cross-sectional area sized larger than the jet and wherein the probe extends beyond the elongate carrier to at least partially define the opening and wherein the probe comprises a portion with a recess sized and shaped to receive a distal end of an energy delivery probe extending from the elongate carrier to stabilize the energy delivery probe;
wherein the elongate carrier is configured to rotate the nozzle around the longitudinal axis to a first position toward the opening to direct the fluid stream toward the opening of the evacuation lumen;
wherein the elongate carrier is configured to rotate the nozzle around the longitudinal axis to a second position opposite the first position and away from the opening to the evacuation lumen to treat the tissue.
