Patent ID: 8915842

Claim:
A surgical device, comprising: an annular sheath configured to be disposed in a body cavity and to receive a surgical instrument in a lumen thereof, the sheath further having a passageway configured to allow fluid to flow therethrough, and the sheath having an annular lumen in a distal portion thereof, the passageway having a plurality of proximal openings that are in fluid communication with the annular lumen and a distal opening in fluid communication with the passageway; and a fluid conduit at least partially located in the distal portion of the sheath and configured to be movable when the sheath is disposed in a body cavity between a first position in which the fluid flowing through the passageway can exit the passageway, enter the annular lumen, and exit the annular lumen through each of the plurality of proximal openings and cannot exit through the distal opening, and a second position in which the fluid flowing through the passageway can exit the passageway through the distal opening and the fluid conduit prevents passageway of the fluid into the annular lumen such that the fluid flowing through the passageway cannot exit through the plurality of proximal openings.
