Knotless suture anchor having discrete polymer components and related methods

A suture anchor for affixing tissue to bone comprising:

• a toggle member that is movable from a low profile insertion position to a large profile position wherein said large profile position provides said suture anchor a large diameter section that affixes said anchor in a bone tunnel;
• a plug member comprising an external surface such that a suture may be looped around said plug;
• and
• a sleeve member having an internal lumen that may receive said plug and compress a suture between said plug and said sleeve to lock said suture in place and wherein each of said toggle member, plug and sleeve member are discrete components.

A knotless suture anchor for securing soft tissue to bone comprising:

• a first component adapted to affix the anchor in a bone tunnel;
• a second component distal to said first component, said second component comprising a suture guide, and a proximal abutment surface adapted to abut a distal surface of said first component;
• a third component distal to said second component, said third component comprising a cavity and a proximal opening, said cavity being adapted to accept said second component and to compress a suture when the second component is within the cavity of the third component thereby locking the suture in place and wherein said second component is made of a polymer;
• and
• wherein said second component comprises a body and exterior surface, and said suture guide comprises a groove disposed about the exterior surface, and a portion of said groove extends across a distal surface of said second component.
