Abstract
The present invention provides a tubing set in cassette form and an irrigation system employing the cassette and tubing set for use in endoscopic procedures. The tubing set includes a generally arcuate cassette which is inserted into the pump housing to effect a change in tubing sets between procedures. A valve assembly and flattened tubing segment are preferably used to provide pressure control/relief in the tubing set/irrigation system. Also provided in combination with the preferred cassette is a fitting for coupling a pressure monitoring line with pressure monitoring equipment in the irrigation system.
