Device for interfacing filamentous or fibrous structures with a real or simulated biological tissue

A device for interfacing at least one filamentous structure, with real or simulated biological tissue, comprising at least one body (10, 20) for anchoring the filamentous structure, said device being characterized in that said body (10, 20) comprises: at least one capstan (12, 22, 22', 22'), said capstan (12, 22, 22') being configured for wrapping the filamentous structure; at least one porous portion (13, 13', 24) having a trabecular structure (300); and system for regeneration, or repair, or replacement, or simulation of tendon and/or ligamentous tissue comprising said device and at least one filamentous structure comprising a plurality of nanofiber assemblies obtained by electrospinning, said plurality of assemblies being arranged to form a single bundle; said bundle being wrapped to the capstan (12).
