Implant used especially as a bone replacement implant or an intervertebral implant comprises fluidically connected cavities enclosing a net volume that in the initial position is smaller than the maximum total volume

摘要

Implant (10) is converted from an initial position in which the implant has a maximum total volume into an insertion position in which the implant has an insertion volume that is smaller than the maximum total volume. The implant comprises a number of fluidically connected cavities. The net volume enclosed by the cavities in the initial position is smaller than the maximum total volume. Preferred Features: The insertion volume is a maximum of 20% of the maximum volume. The implant is made of a bio-absorbable material such as collagen, gelatin, a polymer fleece, a polymer foam, hyaluronic acid, a hyaluronic acid derivative or any mixture of two or more of these materials.
