First Claim
Patent Images
1. A suture anchor comprising:
- an outer body having a distal end a proximal end and an axial bore therethrough;
an inner body receivable within the outer body;
a suture limb captured between the inner body and the outer body by being wrapped around the inner body, a first portion of the suture limb passing out of the outer body whereby it may be connected to a tissue and a second portion of the suture limb passing out of the outer body whereby to allow a tension to be applied to the suture limb by a user;
the inner body having a distal end and a proximal end and wherein the inner body proximal end has outer threads which mate with inner threads on the proximal end of the outer body; and
the outer body having a first configuration in which at least a portion thereof is radially contracted inwardly and a second configuration in which the portion is radially expanded outwardly, and wherein when the outer threads on the inner body are engaged into the outer body inner threads it holds the portion in the second configuration.

Abstract
A suture anchor is disclosed having an outer body with an axial bore which receives and inner body for rotation. Suture passes between the inner body and outer body and rotation of the inner body wraps the suture thereabout locking the suture thereto. Rotation of the inner body also effects radial expansion of at least a portion of the outer body to engage to anchor into a bone hole.
