US Patent 10492856 Surgical fluid management system and method of use

A fluid management system receives fluid from a fluid source and delivers the fluid to a medical probe having a first fluid infusion and aspiration circuit and a second fluid infusion and aspiration circuit. The system also transfers fluid from the medical probe to a collection container. A controller operates a first pump and valve assembly to selectively deliver fluid inflow from the fluid source to one of the first fluid infusion and the second fluid infusion and aspiration circuit. The controller further operates a second pump and valve assembly to selectively transfer fluid outflow to the collection container from one of the first fluid infusion and aspiration circuit of the medical probe and the second fluid infusion and aspiration circuit of the medical probe.
