Zusammenfassung:To provide an implantable biopolymer scaffold excellent in compatibility with bodily tissue and bodily fluids, strength, flexibility, and biodegradability.SOLUTION: Initial synthetic fibers are wound around a high-strength collagen fiber to form a wound subassembly, and the wound subassembly is braided with two or more additional synthetic fibers. The high-strength collagen fiber has a first ultimate tensile strength, and the first additional synthetic fibers have a second ultimate tensile strength, where the first ultimate tensile strength may be in a range of 2 to 15 percent of the second ultimate tensile strength.SELECTED DRAWING: Figure 1 【課題】生体組織および体液との適合性、強度、柔軟性、および生分解性に優れる 埋め込み型生体高分子スキャフォールド (足場)を提供する。【解決手段】高強度コラーゲン繊維の周りに初期合成繊維を巻いて巻かれたサブアセンブリを形成し、前記巻かれたサブアセンブリを2本以上の追加合成繊維と編組する。前記高強度コラーゲン繊維が第1の極限引張強度を有し、前記第1の追加合成繊維が第2の極限引張強度を有し、前記第1の極限引張強度が前記第2の極限引張強度の約2~15パーセントの範囲にあってもよい。【選択図】図1
