Title
(EN) COMPOSITE MATERIAL, PROCESS FOR PRODUCING A COMPOSITE MATERIAL AND MEDICAL DEVICE BASED ON COMPOSITE MATERIAL
(FR) MATÉRIAU COMPOSITE, PROCÉDÉ DE PRODUCTION D'UN MATÉRIAU COMPOSITE ET DISPOSITIF MÉDICAL À BASE DE MATÉRIAU COMPOSITE
Abstract
(EN) The present invention relates to a composite material, in particular a composite material of metals, a process for producing a composite material, and a medical device, in particular an implant, based on the composite material. The composite material comprises at least 5 vol-% of Fe and at least 1 vol-% of Mg or Zn, wherein the composite material comprises a Mg or Zn phase and an Fe phase, wherein the average size of the Mg or Zn phase in at least one dimension is less than 20 µm, in particular less than 10 µm. The medical device, in particular an implant, may be suitable for fixing of bone fractures (as well as fractions of a tendon or a ligament, etc.) and/or corrections and may be capable of exhibiting a targeted failure representing a complete paradigm shift in the treatment of bone fractures and the like.
(FR) La présente invention concerne un matériau composite, en particulier un matériau composite à base de métaux, un procédé de production d'un matériau composite, et un dispositif médical, en particulier un implant, à base du matériau composite. Le matériau composite comprend au moins 5 % en volume de Fe et au moins 1 % en volume de Mg ou de Zn, le matériau composite comprenant une phase Mg ou Zn et une phase Fe, la taille moyenne de la phase Mg ou Zn suivant au moins une dimension étant inférieure à 20 µm, en particulier inférieure à 10 µm. Le dispositif médical, en particulier un implant, peut être approprié pour la fixation de fractures osseuses (ainsi que de fragments de tendon ou de ligament, etc.) et/ou la réalisation de corrections et peut être capable de présenter une défaillance ciblée, ce qui constitue un changement de paradigme complet dans le traitement de fractures osseuses et similaires.
