Umbrella-shaped suture anchor device with actuating ring member

A method of implanting a suture anchor assembly in a bone, comprising:

• I) inserting a suture anchor assembly in a bore hole drilled in a bone, wherein the suture anchor assembly comprises an elongated anchor member having a distal end and a proximal end, a shaft extending proximally away from said anchor member proximal end, and a plurality of wing members extending proximally and radially outward from said anchor member proximal end and terminating in a free end, said wing members being spaced from said shaft;
• an operating member slidably mounted on said shaft for sliding movement relative to said anchor member from a first normal position remote from said anchor member to an operative position in which said operating member is lodged between said shaft and said wing members to thereby restrain said wing members from moving inwardly toward said shaft from the radially outward extending position;
• and suture retaining means in said shaft, and
• II) sliding said operating member of said suture anchor assembly relative to said anchor member thereof from said first position to said operative position.
