Abstract
A suture anchor for affixing soft tissue to bone. The anchor has a hollow outer member, and an actuation member slidably mounted within the outer member. The actuation member has at least two engagement members that are pivotally mounted to the actuation member. Proximal movement of the actuation member with respect to the outer member causes the engagement members to move outward to a deployed position, wherein the engagement members are deployed in bone. A surgical suture is mounted to the anchor.
Claims23
A suture anchor, comprising:
- an outer member having a proximal end, a distal end, an inner cavity, an outer surface, and an inner surface;
- a distal nose member extending from the distal end of the outer member;
- an opening in the proximal end of the outer member in communication with the inner cavity;
- a pair of engagement member slots in said outer member extending through the outer surface and in communication with the inner cavity, said slots having a proximal end and a distal end;
- an actuation member slidably mounted in the cavity of the outer member, the actuation member having a proximal end, a distal end, and an outer surface;
- a cavity in said actuation member;
- a pivot pin mounted in the cavity of the actuation member, the pin member having opposed ends and an outer surface;
- a pair of engagement members pivotally mounted in the cavity of the actuation member about the pivot pin, each engagement member having a proximal end, a distal end, and an outer surface;
- and,
- a camming surface extending distally in the engagement cavity,
- wherein the actuation member is moveable from a first distal position partially within the cavity of the outer member wherein the engagement members are contained within the outer member to a second proximal position partially within the cavity of the outer member wherein at least the proximal ends of the engagement members extend out through the slots of the outer member such that said engagement members may engage bone.

A method of affixing soft tissue to bone, the method comprising:
- providing a suture anchor, the suture anchor comprising:
- an outer member having a proximal end, a distal end, an inner cavity, an outer surface, and an inner surface;
- a distal nose member extending from the distal end of the outer member;
- an opening in the proximal end of the outer member in communication with the inner cavity;
- a pair of engagement member slots in said outer member extending through the outer surface and in communication with the inner cavity, said slots having a proximal end and a distal end;
- an actuation member slidably mounted in the cavity of the outer member, the actuation member having a proximal end, a distal end, and an outer surface;
- a cavity in said actuation member;
- a pivot pin mounted in the cavity of the actuation member, the pin member having opposed ends and an outer surface;
- a pair of engagement members pivotally mounted in the cavity of the actuation member about the pivot pin, each engagement member having a proximal end, a distal end, and an outer surface;
- a camming surface extending distally in the engagement cavity;
- and,
- a surgical suture mounted to the actuation member,
- wherein the actuation member is moveable from a first distal position within the cavity of the outer member wherein the engagement members are contained within the outer member to a second proximal position within the cavity of the outer member wherein at least the proximal ends of the engagement members extend out through the slots of the outer member such that said engagement members may engage bone;
- accessing a bone and drilling a hole into the bone;
- inserting the suture anchor into the hole in the bone and deploying the engagement members into bone surrounding the hole in the bone by pulling proximally on the sutures causing the actuation member to move proximally with respect to the outer member to the second proximal position;
- and,
- engaging soft tissue with the suture and approximating the soft tissue to the bone.

A suture anchor, comprising:
- an outer member having a proximal end, a distal end, an inner cavity, an outer surface, and an inner surface;
- an opening in the proximal end of the outer member, and an opening in the distal end of the outer member, wherein both holes are in communication with the inner cavity;
- a pair of engagement member slots in said outer member extending through the outer surface and in communication with the inner cavity, said w slots having a proximal end and a distal end;
- an actuation member slidably mounted in the cavity of the outer member, the actuation member having a proximal end, a distal end, and an outer surface;
- a distal nose member extending from the distal end of the actuation member;
- a cavity in said actuation member;
- a pivot pin mounted in the cavity of the actuation member, the pin member having opposed ends and an outer surface;
- a pair of engagement members pivotally mounted in the cavity of the actuation member about the pivot pin, each engagement member having a proximal end, a distal end, and an outer surface;
- and,
- a camming surface extending distally in the engagement cavity,
- wherein the actuation member is moveable from a first distal position partially within the cavity of the outer member wherein the engagement members are contained within the outer member and wherein the distal nose member of the actuation member extends out through the distal opening of the outer member to a second proximal position partially within the cavity of the outer member wherein at least the proximal ends of the engagement members extend out through the slots of the outer member such that said engagement members may engage bone.
