An anchor device and system for coupling soft tissue to osseous tissue includes a stopper member that supports a loop of suture material. A fixing member includes features that allow it to be rigidly coupled to surrounding bone and thus hold the stopper member in a cavity within the bone. The loop of suture material, in turn, supports a second suture device, which is coupled to, and thus retains, the soft tissue. In certain embodiments, the stopper member includes a mechanical linkage for coupling it to the fixing member, and surface features that resist withdrawal of the fixing member from the bone. |

1. An anchor comprising: a stopper portion, said stopper portion including a proximal surface, a first internal surface and a second internal surface, said first and second internal surfaces defining respective first and second bores through said stopper portion substantially perpendicular to said proximal surface, said first and second bores being adapted to receive first and second portions of a length of suture therewithin; and a fixing portion, said fixing portion having a surface adapted to be disposed adjacent to a surface of said stopper portion so as to inhibit a motion of said stopper portion within a tissue matrix, said stopper portion including a third longitudinal bore, said third longitudinal bore being adapted to receive a further portion of said length of suture therewithin, said fixing portion including a generally cylindrical external surface, said generally cylindrical external surface including a generally helical thread portion, said generally helical thread portion being interrupted by at least one longitudinal groove, said at least one longitudinal groove being defined in part by an axial surface portion of said generally cylindrical external surface, said axial surface portion being disposed at a radius of said fixing portion substantially coincident with an inner radius of said helical thread portion. |
