Abstract:
A system for minimizing leakage of fluid distending media by the sides of the endoscopic instrument in endoscopic procedures such as arthroscopy, hysteroscopy or laparoscopy. A double-wall flexible tubular sheath having walls containing pressurized fluid is mounted over an endoscopic instrument. The double-wall flexible tubular sheath moves in and out of a natural opening of a tissue cavity or through an incision made in the cavity wall.
