1. A prosthesis intended to be conveyed to an implantation site with the aid of a trocar, comprising:
- at least one flexible biocompatible textile having two opposite faces and a shape defining a longitudinal axis, andat least one reinforcing element for said textile, the reinforcing element comprising at least one semi-rigid elongate rod segment situated in a distal region of the textile, one or more oblique rod segments situated in a proximal region of the textile and a triangular frame arranged between the elongate rod segment and the oblique rod segment, the at least one semi-rigid elongate rod segment fixed to at least one face of the two opposite faces of the textile and extending substantially parallel to the longitudinal axis along the at least one face, the rod segment having a proximal end and a distal end, the distal end provided with at least one fastening element having a shape of a ring and distinct from the textile, the fastening element configured to cooperate with a part of a tool that is able to pass through the trocar, in order to temporarily couple the prosthesis to the tool, wherein the one or more oblique rod segments are situated proximally to the proximal end of the at least one rod segment.

Abstract
The invention relates to a prosthesis (1) comprising a textile (2) of elongate shape defining a longitudinal axis A, and a reinforcing element comprising at least one semi-rigid elongate structure (8) connected to said textile, said structure being substantially parallel to said longitudinal axis A and having a distal end provided with at least one fastening element (4) distinct from said textile and capable of cooperating with a part of a tool (10) that is able to pass through said trocar, in order to temporarily couple said prosthesis to said tool.

20. A method of conveying a prosthesis to an implantation site comprising:
-
providing a prosthesis including at least one flexible biocompatible textile having two opposite faces and a shape defining a longitudinal axis and at least one reinforcing element for said textile, the reinforcing element comprising at least one semi-rigid elongate rod segment situated in a distal region of the textile, one or more oblique rod segments situated in a proximal region of the textile and a triangular frame arranged between the elongate rod segment and the oblique rod segment, the at least one semi-rigid elongate rod segment fixed to at least one face of the two opposite faces of the textile and extending substantially parallel to the longitudinal axis along the at least one face, the rod segment having a proximal end and a distal end, the distal end provided with at least one fastening element having a shape of a ring and distinct from the textile, wherein the one or more oblique rod segments are situated proximally to the proximal end of the at least one rod segment, engaging the one or more fastening elements with a part to a tool thereby coupling the prosthesis to the tool via the fastening elements, introducing the part of the tool coupled to the prosthesis into a proximal orifice of a trocar causing the prosthesis to automatically fold into a compact configuration as the tool and the prosthesis penetrates into the proximal orifice of the trocar, and passing the prosthesis through a distal orifice of the trocar to the site of implantation wherein the prosthesis unfolds from the compact configuration to a spread-out configuration.

21. A prosthesis intended to be conveyed to an implantation site with the aid of a trocar, comprising:
-
at least one flexible biocompatible textile having two opposite faces and a shape defining a longitudinal axis, and at least one reinforcing element connected to at least one face of the two opposite faces of the textile, the reinforcing element comprising at least one semi-rigid elongate structure aligned on the longitudinal axis, one or more oblique rod segments situated at angle relative to the longitudinal axis and a triangular frame arranged between the elongate structure and the oblique rod segment, the rod segment having a proximal end and a distal end, the distal end provided with at least one fastening element having a shape of a ring and distinct from the textile, the fastening element configured to cooperate with a part of a tool that is able to pass through the trocar, in order to temporarily couple the prosthesis to the tool, wherein the one or more oblique rod segments are situated proximally to the proximal end of the at least one rod segment.
