ABSTRACT:
The present invention provides a system and method for irrigating and collecting tissue from a body cavity in a patient. The system includes an irrigation and collection device for injecting an irrigation fluid into the body cavity. The irrigation device injects fluid into the body cavity by creating a positive pressure within the device to expel the irrigation fluid from the device into the body cavity. The irrigation fluid is evacuated from the body cavity by the resulting negative pressure within the device, drawing the irrigation fluid and any loose tissue or particulate material into the device. The irrigation fluid is filtered, collecting the evacuated tissue and particulate material in a collection receptacle thereby isolating the evacuated tissue and particulate material within the irrigation fluid.
