Abstract
Various devices, systems and methods for knotless suturing of tissue are disclosed. These devices allow sutures to be anchored to bone, and more specifically provide a suture anchor which eliminates the need for knotting the suture. Thus, damaged tissue may be re-attached to a substrate tissue. The anchors have a minimum of moving parts may be suited to being a single molded polymer construction. The anchors will find particular utility in hip and shoulder arthroscopy, e.g. labral re-attachment and similar procedures.
Claims19
A method for re-joining damaged tissue with substrate tissue, said method comprising:
- providing a suture coupled with both a first anchor and a second anchor prior to positioning the first anchor or the second anchor in the substrate tissue;
- positioning the first anchor in the substrate tissue;
- capturing the damaged tissue with a portion of the suture disposed between the first anchor and the second anchor;
- positioning the second anchor in the substrate tissue, the second anchor axially aligned end-to-end with the first anchor;
- and
- adjusting the length of the portion of the suture so that the damaged tissue is apposed to the substrate tissue.
A method for anchoring suture to substrate tissue, said method comprising:
- drilling a first hole into the substrate tissue;
- placing a first anchor into the first hole, the first anchor coupled to a first extremity of a suture;
- capturing damaged tissue with the suture, wherein the damaged tissue obstructs visualization of the first hole;
- transmitting light through the damaged tissue such that the first hole is visible therethrough;
- and
- coupling a second extremity of the suture to the first anchor.
