Abstract
Disclosed is an intervertebral implant (1) comprising a central axis (2), a bottom cover plate (3) and a top cover plate (4), which are respectively provided with an exterior surface (7; 8) that extends transversal to the central axis (2), and a central part (10). Said central part (10) is located between the cover plates (3; 4) and is provided with a sleeve (12) encompassing a fiber system (5) that is connected to the cover plates (3; 4) and is embedded in an enveloping body (25) made of a homogeneous material. In analogy with the anatomic structure of the natural disk, the inventive intervertebral implant (1) can transfer occurring compressive forces onto the cover plates (3, 4) thereof as tensile forces that are applied to the individual fibers of the fiber system (5) thereof.
