Abstract
A system for performing irrigation of a body cavity includes a reservoir containing an irrigation liquid, a catheter and a controller. The catheter is configured to be at least partially inserted into the body cavity and has a flushing passage, a drain passage and a retention balloon. A waste drain valve is in fluid communication with the drain passage of the catheter and is movable between a closed configuration, where waste is retained within the drain passage, and an open configuration where waste flows through the drain passage. The controller is in fluid communication with the reservoir and the catheter, and has a pump and a valve assembly. The valve assembly is changeable between configurations where, when the pump is actuated, irrigation liquid is pumped from the reservoir to the retention balloon, from the reservoir to the flushing passage of the catheter and from the retention balloon to the reservoir.
