A method of manufacturing an anchor, the method comprising:

• presenting the anchor comprising an anchor body and one or more barbs extending outwardly from the anchor body, wherein the anchor body comprises a cannula;
• and
• laser cutting a plurality of open portions arranged in at least one array around the anchor body;
• wherein the laser cutting of the plurality of open portions comprises laser cutting a perimeter that encloses each of the plurality of open portions, the perimeter having a length parallel to a longitudinal axis of the cannula and a width perpendicular to the longitudinal axis, wherein the length is greater than the width;
• and
• wherein the laser cutting of the plurality of open portions also comprises laser cutting within the perimeter of each of the plurality of open portions a first end, a second end, and a middle section, the first end comprising a circular shape, the second end comprising a circular shape, and the middle section comprising a linear shape.
