The present invention relates to a reinforcing element (200) for a circular mesh, comprising a plurality of fingers (201) which, at rest, form a conical structure (202) that can open out when the reinforcing element is placed under axial stress, each finger comprising a vertex segment (201a) and a peripheral segment (201b) defining a vertex part (202a) and a peripheral part (202b) of the said conical structure, the said reinforcing element comprising, for each finger, means (201c, 205; 402; 502) of misaligning the said vertex segment and the said peripheral segment, at least when the said reinforcing element is under axial stress, the said misalignment means making it possible, in the said position under axial stress, firstly for the peripheral part of the said conical structure to adopt a planar configuration, and secondly, for the said vertex part of the said structure to maintain a conical shape. The invention also relates to a prosthesis (300) comprising such a reinforcing element (200) associated with a mesh (1). |

1. An implantable reinforcing element, comprising:
a plurality of fingers extending outwardly from a central point defining a vertex of the implantable reinforcing element configured to form a substantially conical structure when the reinforcing element is in a rest configuration, each finger comprising a vertex segment and a peripheral segment, a collection of the vertex segments of the fingers defining a vertex part of the substantially conical structure and a collection of the peripheral segments of the fingers defining a peripheral part of the substantially conical structure, a collection of free ends of the plurality of fingers positioned at an opposite end from the central point which form a base of the substantially conical structure, the plurality of fingers being fixed freely to the central point and configured to allow the substantially conical structure to open out when the base of the conical structure is brought into contact with a substantially planar surface and a pressure force is applied to the reinforcing element from the central point of the substantially conical structure towards the base, a misalignment tie passing through an opening of each of the fingers and configured to misalign the vertex segment and the peripheral segment of each finger, wherein when the reinforcing element is in a position of axial stress the misalignment tie provides for the peripheral part of the conical structure to adopt a substantially planar configuration and to hug the substantially planar surface, and for the vertex part of the structure to maintain a substantially conical shape. |
