Abstract

Fluidic devices, methods, and systems are disclosed. One system may comprises a sheath, a delivery module, and a removal module. The sheath includes a working lumen, a delivery lumen, and a removal lumen. The delivery module is configured to move a fluid from a fluid reservoir and into a body cavity through the delivery lumen. The removal module is configured to move the fluid and a particulate contained therein out of the body cavity through the removal lumen, through a filtration device that removes the particulate, and back into the fluid reservoir. One method comprises placing a distal end of sheath into a body cavity, energizing the working lumen to generate a particulate in the cavity, moving the fluid into the cavity to engage the particulate, and moving the fluid and the contaminant from the body cavity, through a filter for removing the contaminant, and back into the fluid source.
