Title (EN) MEDICAL IMPLANT
(FR) IMPLANT MEDICAL
Abstract:
(EN) A medical implant coated with a polymeric material having hydrophilicity and osteoconductivity. When the implant is embedded in depth in a living body, the polymeric material absorbs moisture to swell up, bringing about an effect of dispersing the external stress applied to the implant. This volumetric increase also brings the implant into close contact with the bone of the implantation site, thus remarkably improving the stability in the early stage of the implantation and more strengthening the osseointegration of the implant in the bone as time passes.
(FR) L'invention concerne un implant médical enduit de matériau polymère ayant des propriétés hydrophiles et ostéoconductrices. Une fois implantée à une certaine profondeur dans un organisme vivant, l'implant absorbe l'humidité via son matériau polymère qui, par son gonflement produit un effet tendant à dissiper la sollicitation externe appliquée sur l'implant. L'augmentation volumétrique considérée a aussi pour effet de mettre l'implant en contact étroit avec l'os du lieu d'implantation, améliorant ainsi remarquablement la stabilité dès les premiers instants qui suivent l'implantation et renforçant encore l'osséointégration de l'implant dans l'os avec le temps.
