Skeletal implant

A skeletal implant of the type to be used to connect at least two elements of a skeleton, the skeletal implant comprising:

• a first part adapted to be connected to at least one of the at least two elements of the skeleton;
• a second part adapted to be connected to another of the at least two elements of the skeleton;
• a variable volume element having a first end coupled to the first part and a second end, the variable volume element being adapted to move the first and second parts away from each other;
• a third part having a first end coupled to the first part and a second end coupled to the second end of the variable volume element;
• a high-pressure chamber supplying fluid to the variable volume element;
• and
• a low-pressure chamber receiving fluid from the variable volume element.

A skeletal implant of the type to be used to connect at least two elements of a skeleton, said implant comprising at least two parts, each of which is capable of being connected to one of said at least two elements, said at least two parts being movable with respect to each other, wherein there is provided, between said at least two parts:

• at least one of:
• a means authorizing a displacement between said at least to parts, from a starting position to a displaced position;
• and
• a means exerting a force between said at least two elements of the skeleton;
• said means being responsive to control means and comprising at least one variable volume element containing a fluid;
• said control means comprising a high-pressure reservoir and a very high-pressure differential variable volume recharging element for sending fluid at high-pressure into said high-pressure reservoir;
• said high-pressure reservoir being connected to said at least one variable volume element via a high-pressure valve;
• said at least one variable volume element being connected to a low-pressure reservoir via a low-pressure valve;
• said very high-pressure differential variable volume recharging element being connected to said low-pressure reservoir via another low-pressure valve;
• and
• said very high-pressure differential variable volume recharging element being responsive to displacements of corporal parts for recharging of said high-pressure reservoir with said fluid.

• said variable volume element being connected to a low-pressure reservoir via a low-pressure valve;
• and
• said high-pressure valve and said low-pressure valve being relatively spaced apart from one another.
