Abstract
Methods and devices are provided for anchoring suture to bone. In one exemplary embodiment, a suture anchor is provided that includes a proximal component, a distal component, and an intermediate component positioned between the distal component and the proximal component. The proximal and distal components can each be configured to move independent of one another and to move relative to the intermediate component. In this way, the proximal, intermediate, and distal components of the suture anchor can be configured to cooperate with one another to prevent removal of the suture anchor from a bone hole in which the suture anchor is disposed and to lock a suture relative to the suture anchor and to the bone hole.
Claims19
A suture anchor, comprising:
- an implantable proximal component of the suture anchor, the proximal component having threads on at least a portion of an external surface thereof, the threads being configured to threadably engage bone, and the proximal component having an inner lumen extending therethrough, the inner lumen of the proximal component having a first central longitudinal axis extending between a proximal end of the proximal component and a distal end of the proximal component;
- an implantable intermediate component of the suture anchor, the intermediate component having at least one hole formed in a side wall thereof and configured to receive a suture, and having an inner lumen extending therethrough and configured to receive at least a portion of the proximal component such that a second central longitudinal axis of the inner lumen in the intermediate component is coaxial with the first central longitudinal axis of the inner lumen in the proximal component;
- and
- an implantable distal component of the suture anchor, the distal component having an inner lumen extending therethrough and configured to receive at least a portion of the intermediate component such that the intermediate component causes the distal component to expand radially outward and press against the bone threadably engaged by the threads, and such that a third central longitudinal axis of the inner lumen in the distal component is coaxial with the second central longitudinal axis of the inner lumen in the intermediate component.
A suture anchor, comprising:
- an implantable proximal component of the suture anchor, the proximal component having threads on at least a portion of an external surface thereof, and having an inner lumen extending therethrough;
- an implantable intermediate component of the suture anchor, the intermediate component having
- an inner lumen extending therethrough configured to receive a distal end of the proximal component therein,
- an internal stop member extending into the inner lumen of the intermediate component, the internal stop member being configured to engage the distal end of the proximal component, thereby preventing the distal end of the proximal component from extending distally beyond a distal end of the intermediate component, and
- a side wall having at least one hole formed therein configured to receive a suture;
- and
- an implantable distal component of the suture anchor, the distal component having an inner lumen extending therethrough configured to receive therein the distal end of the intermediate component such that the intermediate component causes the distal component to expand radially outward.
A suture anchor, comprising:
- an implantable proximal component of the suture anchor, the proximal component having threads on at least a portion of an external surface thereof, and having an inner lumen extending therethrough;
- an implantable intermediate component of the suture anchor, the intermediate component having an inner lumen extending therethrough configured to receive at least a portion of the proximal component, and the intermediate component having a side wall having at least one hole formed therein configured to receive a suture;
- and
- an implantable distal component of the suture anchor, the distal component having an inner lumen extending therethrough configured to receive at least a portion of the intermediate component, wherein distal proximal motion of the distal component relative to the proximal component causes at least the portion of the intermediate component to be advanced into the inner lumen of the distal component and thereby cause the distal component to expand radially outward.
