Patent ID: 8080043

Claim:
A bioabsorbable surgical osteosynthesis plate, operable to be secured by at least one fastener through at least one fastener opening formed in the plate to a bone, said osteosynthesis plate having a first surface and a second surface and a thickness extending between the first surface and the second surface, the plate further comprising a main plane extending parallelly to the first surface and the second surface, the plate being formed to one piece from a spirally oriented preform of a material that is substantially rigid and substantially deformable and dimensionally stable at a first thermochemical state such that the plate is deformable to a deformed state where the plate maintains the deformed state, said material of the plate being oriented parallel to the main plane of the plate so that the plate comprises a continuous gradient of diagonal orientation of the material throughout the thickness of the plate, wherein polymer molecules or segments of polymer molecules are aligned in directions of the diagonal orientation in said material as a result of solid state deformation of the material, said orientation being diagonal in relation to the direction of a reference axis of the plate, wherein the first surface has a diagonal orientation and the second surface has a diagonal orientation such that the diagonal orientation of the first surface and the diagonal orientation of the second surface are in different directions.
