Abstract

A radially expandable knotless tissue anchor including an expandable outer member defining a bore and an inner member slidably positioned within the bore. Relative longitudinal movement of the inner member relative to the expandable member causes a portion of the expandable member to expand radially outwardly. The tissue anchor further includes a length of suture material having a first end affixed to a distal end of the inner member and a second end preferably affixed to a suturing needle. A transverse bore is provided adjacent the distal end of the inner member. A method of knotlessly anchoring a section of tissue to a section of bone having a bore drilled therethrough includes passing the suture through the tissue and positioning the expandable member and a section of tissue within the interior of the bore drilled in bone. Expansion of the expandable member secures the suture between the expandable member and the bone to thereby secure the attached tissue to bone.
