A method of producing a surgical implant, device, or part thereof, made of biodegradable material for performing at least one function selected from the group consisting of supporting, joining and separating tissue and keeping open a tissue cavity. One biodegradable rod which is wound around a winding center into a helical configuration in a manner that between successive winds there is provided a space free of material of the biodegradable rod, and which is reinforced with biodegradable reinforcement element in a biodegradable matrix the reinforcement elements being oriented substantially in a longitudinal direction of the biodegradable rod.

Surgical materials and devices

Bone graft implant

Surgical osteosynthesis composite material, which is self-reinforced i.e. it is formed about the absorbable polymer or copolymer matrix which is reinforced with the absorbable reinforcement units which have the same chemical element percentage composition as the matrix has.

Material for osteosynthesis devices

Surgical device for immobilization of bone fracture, which device comprises at least one, essentially stiff osteosynthesis plate (7) which is located perpendicularly over or through the fracture (6). Additionally the osteosynthesis device comprises at least one firm fixing element (8, 8') which is fastened to bone (5) and/or tightened to its place to go beyond or to perforate the fracture (6) and/or to go beyond the osteosynthesis plate (7) in such a way that the osteosynthesis plate (7), the tightened fixing element (8, 8', 8') and the region of immobilized bone (5) where the fracture (6) exists form an assembly whose stiffness is high enough to confirm the healing of the fracture (6) and that as a consequence of resorption of osteosynthesis plate (7) during the healing of the fracture (6) the stiffness and mechanical strength of the surgical device decrease in such a way that the need to remove the surgical device or part of it at a separate subsequent operation is excluded.
