Implantable system having a dissolution mechanism upon recovery

A system for a controlled loading during a healing phase of a reconstructed or renatured ligament of a human or animal body, comprising:

• an anchor element for implantation in a first bone;
• a connecting element configured to be fixed by the anchor element, the connecting element different from the reconstructed or renatured ligament and wherein the connecting element is configured to dissolve over time so that a retaining and stabilizing function of the connecting element is transferred to the reconstructed or renatured ligament;
• a button-shaped retaining element for the connecting element, the retaining element configured to be attached to a second bone;
• a fastening element configured to fix the connecting element within the anchor element;
• a cushioning device coupled to the fastening element, the cushioning device further comprising a coaxial spring and a sleeve, wherein the connecting element extends through the cushioning device;
• wherein a proximal end of the sleeve is pushed into the spring so that the spring partially surrounds the sleeve and so that the sleeve does not extend through the entire length of the spring;
• wherein the cushioning device and the fastening element are both disposed in the anchor element;
• wherein the connecting element and the retaining element comprise a self-dissolving, bio-resorbable material;
• and
• wherein the retaining element provides two apertures with a middle web disposed between the two apertures, and one end of the connecting element is guided through one of the two apertures, back through the other of the two apertures, and around the middle web of the button-shaped retaining element and spliced, welded, or glued to itself.
