  • Self-sealed irrigation system
    Patent number: 6638236
    Abstract: A self-sealed irrigation system for supplying a treatment fluid to a treatment site is disclosed. The system includes a flexible containment member that has a delivery channel which delivers treatment fluid to the treatment site, a sealing channel supplied with a suction force, and a recovery channel. The delivery channel delivers the treatment fluid to the treatment site. The recovery channel removes spent treatment fluid from the treatment site. The sealing channel hermetically seals the containment member to the body surface surrounding the area to be treated. The containment member is designed such that any spent treatment solution which should by-pass the recovery channel is drawn into the sealing channel thereby preventing any treatment fluid from leaking to the outside environment. The containment member is connected to a suction pump which circulates treatment fluid through the treatment site and a reservoir which supplies the treatment fluid to the system.
