PROBLEM TO BE SOLVED: To provide a regeneration material for a rotator cuff and a shoulder intra-articular structure, which when used for healing the shoulder intra-articular structure with a wide range of injury and a rotator cuff injury with a large torn size, keeps strength during the period of tissue regeneration while urging the tissue regeneration, and also regenerates the shoulder intra-articular structure and rotator cuff tissue with high mechanical strength without thinning the tissue, and also to provide a regeneration material for a rotator cuff and a shoulder intra-articular structure, which reinforces the injured tissue even when the original tissue remains but is weakened or thinned.SOLUTION: The regeneration material for a rotator cuff and a shoulder intra-articular structure comprises a laminate comprising a nonwoven layer made of a bioabsorbable material and a fabric structure layer made of a nonbioabsorbable material.COPYRIGHT: (C)2013,JPO&INPIT【課題】損傷が広範に及ぶ肩関節内構成体や断裂サイズの大きな腱損傷の治癒に用いた場合に、組織再生を促しつつ組織再生の間の強度を保持し、かつ、機械的強度の高い肩関節内構成体や腱組織を菲薄化することなく再生できる腱板及び肩関節内構成体の再生材料を提供する。また、原組織が残存するも脆弱化あるいは菲薄化している場合にも、損傷された組織を補強することができる腱板及び肩関節内構成体の再生材料を提供する。【解決手段】生体吸収性材料からなる不織布層と、生体非吸収性材料からなる繊維構造体層との積層体からなる腱板及び肩関節内構成体再生材料。【選択図】 図1
