The invention provides implantable tissue graft materials composed of a collagenous tissue scaffold and a biocompatible agent bonded to the tissue scaffold via an activated photoreactive group. The invention further provides methods including steps of obtaining a tissue graft material comprising a collagenous tissue scaffold; contacting the collagenous tissue scaffold with a biocompatible agent composition that includes biocompatible agent and one or more photoreactive groups; and treating the collagenous tissue scaffold and biocompatible agent composition to activate the photoreactive groups and bond the biocompatible agent to the tissue scaffold via one or more activated photoreactive groups. Implantable prostheses formed of the tissue graft material are also contemplated.
该发明提供了由胶原组织支架和通过活化光反应基团与组织支架结合的
生物相容剂组成的可植入组织移植材料。该发明还提供了包括以下步骤的方法:获得包括胶原组织支架的组织移植材料;将胶原组织支架与包括
生物相容剂和一个或多个光反应基团的
生物相容剂组成物接触;并处理胶原组织支架和
生物相容剂组成物以激活光反应基团并通过一个或多个活化光反应基团将
生物相容剂与组织支架结合。还可以考虑由该组织移植材料形成的可植入假体。
