Abstract
Abstract The suture anchor comprises a first main body (11) of a generally cylindrical shape having a front portion (1), a rear portion (2), a longitudinal axis (3), a curved surface (4) with protrusions (5), a central through-going bore (19) extending from said front portion (1) to said rear portion (2), and a longitudinal slit (12) which opens at said front portion (1) and curved surface (4) and is closed at said rear portion (2). It further comprises a second conical body (14) having a smaller base (15), a larger base (16), a curved surface (17) and a longitudinal axis (13), said second conical body (14) being coaxially introducible with its smaller base (15) into said slit (12) thereby causing expansion of said first main body (11). The second conical body (14) is provided with a through-hole (6) running transversely to said longitudinal axis (13) and two channels (7) positioned on said curved surface (17) and extending from the orifices (18) of said through-hole (6) to said smaller base (15).
