Method and apparatus for attaching tissue to bone, including the provision and use of a novel knotless suture anchor system, including a novel locking element
First Claim
1. Apparatus for securing a suture to a bone, the apparatus comprising:
- an elongated body having a distal end, a proximal end, and a lumen extending between the distal end and the proximal end, the lumen comprising a distal section and a proximal section, the distal section of the lumen having a wider diameter than the proximal section of the lumen;
a window extending through the side wall of the elongated body and communicating with the lumen, the window being disposed in the vicinity of an intersection between the distal section of the lumen and the proximal section of the lumen and being sized to receive a suture therein;
an elongated element extending through the lumen of the elongated body, the elongated element comprising a proximal end and a distal end, wherein the elongated element comprises a pull line terminating in a loop; and
a locking element mounted to the distal end of the elongated element and disposed in the distal section of the lumen, wherein the locking element comprises at least one filament extending through the loop of the pull line;
whereby, when the elongated body is disposed in a bone, and the suture extends through the window and into the lumen, and the pull line is thereafter moved proximally so as to move the at least one filament proximally, proximal movement of the at least one filament causes the at least one filament to capture the suture extending through the window and into the lumen to the elongated body, whereby to secure the suture to the bone.

18. A method for securing a first object to a second object, the method comprising:
-
providing apparatus comprising; an elongated body having a distal end, a proximal end, and a lumen extending between the distal end and the proximal end, the lumen comprising a distal section and a proximal section, the distal section of the lumen having a wider diameter than the proximal section of the lumen; a window extending through the side wall of the elongated body and communicating with the lumen, the window being disposed in the vicinity of an intersection between the distal section of the lumen and the proximal section of the lumen and being sized to receive a first object therein; an elongated element extending through the lumen of the elongated body, the elongated element comprising a proximal end and a distal end; and a locking element mounted to the distal end of the elongated element and disposed in the distal section of the lumen; wherein the elongated element comprises a pull line terminating in a loop; and wherein the locking element comprises at least one filament extending through the loop; extending the first object through the window; positioning the elongated body in the second object; and moving the locking element proximally, such that proximal movement of the locking element causes the locking element to capture the first object to the elongated body, whereby to secure the first object to the second object.

19. Apparatus for securing a suture to a bone, the apparatus comprising:
-
an elongated body having a distal end, a proximal end, and a lumen extending between the distal end and the proximal end; an elongated element extending through the lumen of the elongated body, the elongated element comprising a proximal end and a distal end, wherein the elongated element comprises a pull line; and a locking element mounted to the distal end of the elongated element and disposed in the lumen of the elongated body, wherein the locking element comprises at least one fiber, wherein the at least one fiber is coupled to the pull line; whereby, when the elongated body is disposed in a bone, and a suture extends at least partially through the lumen of the elongated body, and the pull line is thereafter moved proximally so as to move the at least one fiber proximally, proximal movement of the at least one fiber causes the at least one fiber to capture the suture to the elongated body, whereby to secure the suture to the bone. - View Dependent Claims (20, 21)
