Abstract
A system for controlling the infusion of fluid to an operating field at a selected predetermined pressure, as a counterpart to an instrument for severing material of an object in the field, and for evacuating through a passage the severed material from the field in a suspension or emulsion of the infusion fluid. The system provides a means for maintaining a constant differential pressure between the operating field and its infusion line and the pressure in the line communicating with the passage through which material is being evacuated at the time a reverse fluid flow mode of operation is initiated in the system to send fluid down the passage through which the severed material is normally evacuated.
