Abstract

A view optimizing assembly, method and kit for use in combination with a laparoscope having a lens located on the shaft tip of the laparoscope, and a source of insufflation CO2. The invention includes a multi-lumen sheath assembly, a deflector assembly in fluid communication with the lumens of the sheath assembly, wherein the flow of CO2 through the lumens forms a vortex when coming into contact with the deflector assembly, thereby preventing fogging of the laparoscope lens.
