    • The present invention relates to a process for producing an implant for medical purposes, to the implant obtainable by the process, and to the bioreactor used for the production of the implant. The implants of the invention can be used as implantable prostheses having essentially the functional characteristics of the following tissues: ligaments and tendons, bone and chondrogenic tissues, e.g. intervertebral discs, and combinations of bone tissue with cartilage tissue, e.g. sections of joints having the cartilaginous surface of a joint surface hacked by bone tissue. According to the invention, a porous matrix material is incubated under cell culture conditions with cells while the matrix is exposed to positive pressure on one side and negative pressure on another side for effective colonization of the matrix.
    • 本发明涉及用于医疗用途的植入物的制造方法,可通过该方法获得的植入物和用于生产植入物的生物反应器。 本发明的植入物可以用作具有基本上具有以下组织的功能特征的可植入假体:韧带和腱,骨和软骨形成组织,例如, 椎间盘,以及骨组织与软骨组织的组合。 关节表面具有被骨组织侵入的关节表面的软骨表面。 根据本发明,将多孔基质材料在细胞培养条件下与细胞一起培养,同时将基质暴露于一侧的正压力并在另一侧暴露负压以有效地定植基质。
