Abstract: A sealing apparatus for an anatomical part comprises a support collar that comprising an annular body. An elastic sealing membrane is positioned within the support collar. The sealing membrane defines an annular sealed chamber having a given inner diameter in a natural state of the elastic material. A port in the sealing apparatus is in fluid communication with the chamber. The port is adapted to be in fluid communication with a device for reducing pressure in the chamber to increase the given inner diameter of the chamber in a collapsed state, so that an anatomical part may be inserted into the sealing apparatus. A sealing apparatus and accessories are also provided, as is a method for sealing an anatomical part in an inner cavity of an accessory.
