ted that the beneficial effect of the fact that the protrusions are positioned near to each other also occurs when the ratio between the height of the body and the average wall thickness does not fulfil the abovementioned condition, by which explicitly the possibility is preserved to claim this feature separately from the feature that the height of the body is at most 6 times the average wall thickness of the body.
A further embodiment of the bone plug according to the invention is characterized in that the material of the body of the blocking element has at least nearly elastomeric properties. A body of an elastomeric material is nearly incompressible, whereby the axial compression is nearly fully converted in a radial expansion without loss of volume. In case of the known bone plug an axial compression will in contrary not only result in a radial expansion, but the body itself is also compressed, which means that the volume decreases. Hereby, the bone plug according to the invention will, at equal axial compression, achieve a larger radial expansion than the known bone plug and the bone plug according to the invention will better be fixed in the canal than the known bone plug.
It is noted that the beneficial effect of a body of an elastomeric material also occurs when the ratio between the height and the average wall thickness does not fulfil the aforementioned condition by which explicitly the possibility is preserved to claim this feature separately from the feature that the height of the body is at most 6 times the average wall thickness of the body.
A preferred embodiment of the bone plug according to the invention is characterized in that the material of the body of the blocking element is composed mainly from a mixture of gelatine, glycerine and water. It is noted that a material composed from a mixture of gelatine, glycerine and water is known on itself and that it is known to use such a material for the production of bone plugs. This known application for bone plugs however is only used in order to obta
