A supporting structure formed from a single wire-like element (10) is used in an implant (1) for use in human or animal bodies for closing holes etc. or for making connections, where the supporting structure has a primary form (first operating state) with a large length to diameter (L/D) ratio along one axis (63) and a secondary form with a small L/D ratio An implantable device (1) for use in human or animal bodies for closing holes, cavities, passages in organs etc. or for making definite connections between walls, organs, cavities etc., has a supporting structure (SS) with a proximal part (20) and a distal part (30), which shows a large length to diameter (L/D) ratio along one axis (63) in a first operating state (primary form) and a small L/D ratio in a second operating state (secondary form). The supporting structure (SS) is formed from a single wire-like element (10). Independent claims are also included for (1) A positioning system for (1), with a feed element (5), a guide wire (6, 9) and/or inner mandrel and retaining wire(s) (80, 81), in which wires (6) and (80, 81) are attached to the proximal end of (1), which can be converted from the primary form into the secondary form and vice versa by moving these wires relative to element (5) (2) a set comprising the above positioning system and one or more implantable devices (1) (3) a method for the production of (1) by winding the form for a base supporting structure from a wire element (10), annealing the form to stabilize it, converting the structure from the base form to the required secondary form and then annealing the secondary form to stabilize and imprint it. |
