Abstract: An apparatus for obtaining an artificial erection of the male genital organ including an elongate, generally tubular, body partially defining a vacuum changer adapted to accommodate the organ in a distended condition, the tubular body having an opening at one end to receive the organ and a substantially continuous peripheral rim adjacent the opening to seal the vacuum chamber around the organ, the other end of the body being substantially closed and including a manually operable pump adapted selectively and progressively to evacuate the vacuum chamber such that, in use, the resultant differential pressure causes blood to flow into the organ and induce an artificial erection.

Abstract: A dimensionally recoverable body, which is preferably heat-recoverable, has a body wall which is provided with a plurality of locking elements that are engageable with each other, or are engageable with corresponding elements located on a separate partition, to furcate the body into a plurality of channels.The body may be used for enclosing branch-offs in electrical cables in order to protect the enclosed branch-off from the environment.
