ABSTRACT:
A method and apparatus for use in endoscopic examination of a hollow internal organ, such as hysteroscopic examination of the uterus, includes an inflatable cuff for infusing a pressurized viscous fluid into the interior of the uterine cavity for minimizing distortion of an image of the organ interior viewable through the endoscope. The viscous fluid is an optically clear innocuous liquid having a predetermined viscosity such as between 130 and 300 centistokes at 20.degree. C, and a predetermined optical density, such as a refractive index of 1.3912 at 21.degree. C. This viscous fluid is contained in a self-contained sterile packet reservoir which is removably retained within the inflatable cuff with the viscous fluid being pressurized and released from the reservoir into the endoscope to be infused into the organ interior under the controlled pressure of the inflated cuff surrounding the fluid reservoir packet.
