Abstract
A bone anchor includes an anchor body configured to be retained within bone. The anchor body includes a restrictor defining an opening having a first portion for permitting passage of a member therethrough, and a second portion restricting passage of the member therethrough. The member is movable between the first and second portions in a direction non-parallel to a direction of passage of the member through the opening. The restrictor includes an edge lining the opening oriented obliquely to a direction of passage of the member through the opening. The anchor body includes one or more resilient members with sharp, proximal edges for penetrating bone tissue.
Claims24
A bone anchor comprising:
- an anchor body configured to be retained within bone, the anchor body including a restrictor defining an opening having a first portion for permitting passage of a member therethrough, and a second portion restricting passage of the member therethrough, the member being movable between the first and second portions in a direction non-parallel to a direction of passage of the member through the opening.
A tissue repair system comprising:
- a first bone anchor including a first anchor body configured to be retained within bone,
- a second bone anchor including a second anchor body configured to be retained within bone, and
- a flexible member coupling the first and second bone anchors, at least one of the first and second anchor bodies includes a restrictor defining an opening having a first portion for passage of the flexible member therethrough, and a second portion limiting passage of the flexible member therethrough, the flexible member being movable between the first and second portions in a direction non-parallel to a direction of passage of the member through the opening.
A bone anchor, comprising:
- an anchor body configured to be retained within bone, the anchor body including a restrictor defining an opening for passage of a member therethrough, the restrictor including an edge lining a wall of the opening oriented such that upon movement of the member through the opening in a first direction, the member is also moved non-parallel to the first direction.
A method comprising:
- placing an anchor in bone, the anchor body including a restrictor defining an opening having a first portion for permitting passage of a member therethrough, and a second portion restricting passage of the member therethrough,
- moving the member between the first and second portions in a direction non-parallel to a direction of passage of the member through the opening.
