Abstract:
The invention relates to a prosthesis (1) for the repair of an inguinal hernia comprising: a textile (2) of elongate shape, a resilient frame (3) connected to said textile, characterized in that said frame comprises a convex cranial segment (3c), a caudal segment (3d), a lateral corner segment (3b) joining together the convex cranial segment and the caudal segment, and a folding segment (5) joining a medial end of said convex cranial segment to a point located on the caudal segment while leaving the region of the medial end of the textile free of any frame,said frame being able to adopt an unstressed configuration, in which said textile is deployed, and a stressed configuration, in which said convex cranial segment, said caudal segment and said folding segment are substantially collected together and aligned on one folding direction, said textile forming thereby at least one fold along said folding direction.
