Definition : Systems designed for use during therapeutic procedures (mostly surgical) performed inside a cavity (e.g., uterus, a joint cavity) to keep the cavity filled with pressurized distention solution. These systems should keep the minimum pressure necessary to distend the cavity without exceeding a safe maximum level. Irrigation/distention systems typically consist of an electrically powered pump (manual pumps and gravity are also used), tubing from the pump to an inflow cannula or catheter placed in the cavity to be distended, and controls. Hysteroscopic and arthroscopic procedures are frequently performed using these systems.
