Abstract
Abstract A suture anchor device having an anchor member with outwardly extending wing members and an actuating wedge member. The suture anchor device is inserted into a bore hole in a bone as part of an orthopedic surgical procedure wherein soft tissue such as a tendon or ligament is attached to the surface of the bone. The wing members are spread outwardly by the wedge member to lock the suture anchor device in the bone. The suture anchor has similar utility in soft tissue applications.

Claim 7
Dependent Claim
48 words
The assembly according to claim 5, wherein said sleeve and said shaft have cooperating locking means for locking said sleeve to said shaft when said sleeve is in said operative position, whereby said wing members are prevented by said locked sleeve from deflecting inwardly from said outward position.
Claim 8
Dependent Claim
48 words
The assembly according to claim 2, wherein said sleeve and said shaft have cooperating locking means for locking said sleeve to said shaft when said sleeve is in said operative position, whereby said wing members are prevented by said locked sleeve from deflecting inwardly from said outward position.
