A device for moving a first object relative to a second object, which device comprises a first part, which can be fixed to the first object, and a second part, which can be fixed to the second object. The first part comprises an elongated portion, along which the second part can move, which second part is provided with a clamping member, which is capable of clampingly engaging the elongated portion. The clamping member comprises shape memory metal, which gives the clamping member a clamping shape or a releasing (non-clamping) shape, depending on the temperature of the shape memory metal. The device may be suitable for being implanted into a human or animal body, whereby the first object is a first bone portion and the second object is a second bone portion, which bone portions are to be moved relative to each other.
A device for moving a first object relative to a second object, said device comprising a first part fixed to said first object and a second part fixed to said second object, said first part comprising a centrally disposed elongated rod-like portion, along which said second part can move, said second part being provided with a clamping member disposed about said elongated portion for engaging said elongated portion and which comprises shape memory metal for giving said clamping member a clamping shape or a releasing shape depending on the temperature of the shape memory metal.
A method for moving two objects relative to each other with a relative movement device comprising a first part including a centrally disposed elongated rod-like portion and a second part including a clamping member disposed about said elongated portion comprising shape memory metal which can be heated or cooled to yield a clamping shape or a releasing shape so as to clamp onto or release from said elongated portion of said first part, said method comprising the steps of:
