Abstract: 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.

Abstract: A device for stabilizing a joint, more particularly for a knee joint, comprising a first fixing splint (3), a second fixing splint (5) and a movement control mechanism (7 and 9) bridging over the joint and having flexible connector (8), which to the sides of the joint connects the first fixing splint (3) with the second fixing splint (5). The flexible connector (8) extends from one front side of the first fixing splint (3) on either side past the joint to a rear region of the second fixing splint (3) in order to bias the first fixing splint toward the joint and to the rear and to bias the second fixing splint (5) toward the joint and to the fore.
