An anchor for securing suture to tissue, the anchor comprising:
an elongated body having a distal end and a proximal end, the distal end having a distal slot extending proximally into the elongated body, and the proximal end having a proximal slot extending distally into the body;the distal slot comprising a wide section and a narrow section, wherein the wide section has a width such that the suture is slidably accommodated therein and the narrow section has a width such that the suture is bound therein, and further wherein the wide section is disposed distally of the narrow section. |

1. A method for securing a first element to a second element, the method comprising the steps of:
providing a system comprising:
a suture;at least two anchors, each anchor comprising:
an elongated cylindrical body having a distal end, a proximal end, a longitudinal axis extending between the distal end and the proximal end, and a cylindrical outer surface radially offset from the longitudinal axis, the distal end having a distal slot opening on the cylindrical outer surface of the body and extending from the distal end of the body proximally along the longitudinal axis of the body, and the proximal end having a proximal slot opening on the cylindrical outer surface of the body and extending from the proximal end of the body distally along the longitudinal axis of the body; andthe distal slot comprising a wide section and a narrow section, wherein the wide section has a width such that the suture is slidably accommodated in the wide section and the narrow section has a width such that the suture is bound in the narrow section, and further wherein the wide section is disposed distally of the narrow section;wherein the suture is initially disposed within the wide section of the distal slot of each of the at least two anchors so that the suture is slidable relative to the at least two anchors; andan inserter, the inserter comprising a hollow elongated shaft having a sharp point disposed eccentric to the longitudinal axis of the hollow elongated shaft, and further wherein the suture and the at least two anchors are disposed within the lumen of the hollow elongated shaft; passing the inserter through the first object and the second object so that the sharp point of the inserter resides on the far side of the second object; ejecting the first anchor on the far side of the second object; tensioning the suture so that the suture is drawn into the narrow section of the distal slot of the first anchor, whereby to bind the suture to the first anchor; withdrawing the inserter out of the first object and the second object; moving the inserter laterally; passing the inserter back through the first object and the second object so that the sharp point of the inserter resides on the far side of the second object; ejecting the second anchor on the far side of the second object; tensioning the suture, and withdrawing the inserter out of the first object and the second object, so that the suture is drawn into the narrow section of the distal slot of the second anchor, whereby to bind the suture to the second anchor. |
