The method of fixing soft tissue to bone includes placing an anchor device superficial to a segment of soft tissue superficially juxtaposed to a unicortical blind hole in a bone, the anchor device having a relaxed state characterized by a first outer dimension. The method includes driving the soft tissue segment into the blind hole using the anchor device. The anchor device transiently constricts to a constricted state during insertion through the blind hole, the constricted state characterized by a second outer dimension that is smaller than the first outer dimension. The method includes trapping a portion of the soft tissue segment between a portion of the anchor device and a portion of the bone when at least a portion of the anchor device is disposed sub-cortically and relaxes towards the relaxed state. Related devices, systems and methods are also described.
