A tissue expansion device is composed of a hollow expanding pouch (5) made of resorbable material that can be attached to a cannula (6). The pouch (5) can be filled with biocompatible materials, one or more times in a few days interval, after the insertion of the device. While filling the pouch (5) every few days, the tissue expands and the filling material, if it is bioactive, starts to function. The cannula (6) is connected to the pouch (5) in one side and in the other side it can be filled and closed with a screw (7). There are three fixation components. One fixating components is slot (8) and the other two are holes (9) for sutures. |
