Expanding suture anchor

Suture anchor comprising

• A) a first body 11 of a generally cylindrical shape having a front portion (1), a rear portion (2), a longitudinal axis (3), a curved surface (4), 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 at said curved surface (4) and is closed at said rear portion (2);
• B) 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), said second conical body (14) being provided with a through hole (6) running transversely to said longitudinal axis;
• and
• C) two channels (7) positioned on said curved surface (17) of said second conical body (14) extending from the orifices (18) of said through hole (6) to said smaller base (15), said channels (7) having a depth exceeding the smallest diameter of said through hole (6).

Suture anchor comprising

• A) a first main body (11) of a generally cylindrical shape having a front portion for facing a body member to be treated (1), a rear portion (2), a longitudinal axis (3), a curved surface (4), 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 at said curved surface (4) and is closed at said rear portion (2);
• B) a second body (14) having a smaller base (15), a larger base (16), a curved surface (17) and a longitudinal axis (13), said second body (14) being coaxially introducible with its smaller base (15) into said slit (12) thereby causing expansion of said first main body (11), said second body (14) being provided with a through-hole (6) running transversely to said longitudinal axis (13);
• and
• C) two channels (7) positioned on said curved surface (17) of said second body (14) and extending from the orifices (18) of said through-hole (6) to said smaller base (15).
