摘要:
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, comprises a flat section having first and second surfaces defining a main plane (the sheet plane) of the plate. The plate is formed from a polymer material (including polymer, copolymer and/or polymer alloys) that is oriented multiaxially and is substantially rigid and substantially deformable at a first thermochemical state. In the multiaxially oriented structure of the plate the polymer material is arranged according to three or more different orientation axes along the main plane of the plate as a result of solid state drawing of the plate. The polymer material of the plate has isotropic mechanical tear properties in different directions along the main plane of the plate.
摘要:
A biodegradable composite material or device including at least one biodegradable polymer matrix material and at least one filler component. The material or device has an initial shape and at least one evolved shape. The evolved shape is different from the initial shape. The initial shape is adapted to change towards the evolved shape. The filler component is adapted to accelerate and/or amplify the transformation from the initial shape towards the evolved shape when the external stimulus for transformation is given by physiological conditions. Also a method to control the shape transformation rate of a composite material or device.

摘要:
The present invention relates to a bioabsorbable band system for securing a bone fracture, or an osteotomy, or a soft tissue on a bone, the bioabsorbable band system comprising a needle system and a bioabsorbable band (1) including a bioabsorbable locking member (2). The bioabsorbable band (1) comprises a length having an at least partially oriented structure. The bioabsorbable band further comprises a locking mechanism with a locking member (2). The present invention also relates to a method for producing the bioabsorbable band (1).
