The present invention relates to a suture anchor, and more specifically relates to a suture anchor for anchoring a lead.
Suture anchors often require that a suture be tied in direct contact with the material (often silicone or another similar material) forming the suture anchor and around the suture anchor in order to secure the suture anchor around a lead and, in turn, secure the lead in place with respect to a patient. However, tying sutures in direct contact with silicone (or another similar material) can create various risks due to different physicians tying sutures with varying degrees of force. Such risks include cutting through the silicone or other material of the suture anchor with the suture (if too much force is used in tying the suture) or improper securing of the lead (if too little force is used in tying the suture). Because of the inability to control the force with which a physician ties the suture around the suture anchor, there is a relatively high risk of failure of the suture anchor, for instance, because too much force or too little force was used in tying the suture around the suture anchor.
