In one aspect, the present disclosure relates to a surgical device including an anchor body having an opening, the anchor body having a copolymer composition including polylactide-co-glycolide and calcium carbonate, wherein the calcium carbonate comprises more than 30% but less than 40% of the weight of the composition; and a flexible member passing through the opening, wherein deformation of the device occurs at body temperature. The present disclosure also relates to an oriented polymer material having a copolymer composition including a polylactide-co-glycolide and calcium carbonate, the calcium carbonate comprising more than 30% but less than 40% of the weight of the composition, wherein the material changes shape upon introduction to an environment having a temperature that is lower than a relaxation temperature of the material. A method of repairing soft tissue and other surgical devices are also disclosed.
