1. A medical implant comprising:
- an elongated helix;
at least one part of the helix preformed to define a secondary structure comprising a first face loop, a second face loop, a third face loop and a fourth face loop, the first, second, third and fourth face loops of substantially identical size;
said secondary structure biased to form a polyhedral tertiary structure, the polyhedral tertiary structure comprising a polyhedron, wherein the faces of the polyhedron are built up by the first face loop, the second face loop, the third face loop and the fourth face loop; and
the polyhedron further comprising at least on additional loop coplanar to the plane of the first face loop of the polyhedron for reducing the risk of damage at the placement site,wherein the at least one additional loop is smaller than the first face loop.

Abstract
The invention relates to a medical implant (1′) in the form of an elongated helix wherein at least one part of the helix is preformed in such a manner that it has a secondary structure of identically sized loops which it assumes during implantation at the placement site, with said structure in turn forming at the placement site during implantation a polyhedral tertiary structure, and the polyhedron being provided with at least one additional loop.
