1. A suture anchor for fixation within an anatomical structure, the suture anchor comprising:
an anchor body elongated along a direction of elongation, the anchor body defining a central axis, the anchor body having a flat geometry in a neutral configuration such that, in the neutral configuration, the anchor body defines a thickness along a transverse direction and a width along a lateral direction, wherein the transverse direction is perpendicular to the central axis, the lateral direction is perpendicular to the transverse direction, and the width is greater than the thickness in the neutral configuration; and
an actuation member contacting the anchor body at a first location of the anchor body, the anchor body having first and second anchor body tails extending away from the first location, the first and second anchor body tails being braided together along a portion of the actuation member from the first location to a second location of the anchor body spaced from the first location so as to define a braided suture anchor construct,
wherein the actuation member is configured to apply a force to the anchor body so as to actuate the anchor body from a first configuration, in which the anchor body defines a first maximum thickness along a second direction that is angularly offset from the direction of elongation, to an expanded configuration, in which the anchor body defines a second maximum thickness along the second direction, wherein the second maximum thickness is greater than the first maximum thickness;
wherein the first and second anchor body tails contact each other at the second location, such that the first and second locations define first and second ends of the braided suture anchor construct, and the braided suture anchor construct defines a length extending between the first and second ends along a longitudinal construct direction;
wherein the actuation member comprises:
a first actuation member tail that extends from the first location and away from the portion of the actuation member; and
a second actuation member tail that extends from the second location and away from the portion of the actuation member;
wherein the actuation member penetrates at least one of the first and second anchor body tails at the second location; and
wherein a portion of the anchor body is folded so as to define a loop extending from the first location, the braided suture anchor construct is bent such that 1) the first and second actuation member tails each extend through the loop and 2) the loop extends around at least one of the first and second ends of the braided suture anchor construct.
