Description
使用時、本発明のパテまたは他の適合するインプラント組成物は、例えば、疾病、欠損、または外傷の場所を治療する、および/または一部の例では、人工関節固定を促進するなどのために組織成長(例えば骨または軟骨の成長)が望ましい部位に移植される。組成物の適合する特性により、空洞、欠損、または新たな組織成長が望ましい他の領域内でのその位置決め、成形、および/または型成形が可能になる。特に有利な実施形態では、適合する材料は、骨インプラント部位において本体の隣接する軟組織によって衝突されたときの相当な圧縮に耐える十分な三次元の完全性を提供することが望ましい、形状保持特性を有するパテである。
rhBMP−2の緩衝水溶液(テネシー州、メンフィスのMedtronic Sofamor Danek社製INFUSE(登録商標)骨移植片で準備された1.5mg/ml溶液)9mlが乾燥性の多孔性本体内に画定された貯留部に加えられた。本体は、中央に配置された矩形の貯留部を有する、全体が矩形の形状のものであった。加えられた水溶液の量は貯留部内にたまり、時間をかけて本体中に染み込んだ。多孔性本体は、18ccの体積を有し、約3.8グラムの重量であった。乾燥性の多孔性本体は、不溶性コラーゲン繊維、酸可溶性コラーゲン、およびセラミック顆粒(ceramic granules)の水性懸濁液を型に入れ、次いで凍結乾燥することによって調製されており、約85%の多孔率を示し、以下のもので構成されていた。
