Abstract
An irrigation system for arthroscopy of a joint includes a high pressure bleed valve assembly and a monitor check valve assembly to control fluid communication to the joint via suitable tubing for the purposes of directing fluid inflow, joint fluid pressure monitoring, and to assist with connection of the tubing for an arthroscope and cannula inserted into the joint. The high pressure bleed valve assembly is pressure responsive to direct fluid to the joint via alternative paths.
