ABSTRACT:
A pressure regulation device utilized in an irrigation system. The pressure regulation device includes an inflatable air bladder within a housing in which a flow-through egress bladder connected to the irrigation site is placed. An operator may inflate the air bladder which is in contact with the egress bladder to restrict the flow of irrigation fluid to thereby increase the fluid pressure at the irrigation site such as a joint capsule. Once the fluid pressure in the egress bladder displaces air in the air bladder an equilibrium is reached between the air pressure in the air bladder and fluid pressure in the egress bladder and joint capsule. The operator may control the fluid pressure in the joint capsule by controlling the air pressure in the air bladder. To reduce pressure at the irrigation site, the operator deflates the air bladder to allow for increased fluid flow through the egress bladder. Further, a method of regulating the pressure in an irrigation system and an irrigation system including a pump, catheters for providing access to and egress from the irrigation site and a pressure regulation apparatus in communication with a line from the egress catheter, all connected in series with one another, are disclosed.
