IMPLANTABLE DEVICE WITH IMPROVED SURFACE CHARACTERISTICS

An implantable device (1) comprises a polymer structure (40) having an outer surface facing a surrounding tissue when the implantable device (1) is implanted in a subject body. At least a portion of the surface of the structure (40) has a semi-random pattern of extending micropillars (50). The semi-...

Beschreibung
Zusammenfassung:	An implantable device (1) comprises a polymer structure (40) having an outer surface facing a surrounding tissue when the implantable device (1) is implanted in a subject body. At least a portion of the surface of the structure (40) has a semi-random pattern of extending micropillars (50). The semi-random pattern of micropillars (50) on the surface contributes to advantageous surface characteristicsof the implantable device (1) in terms of reducing adhesion viable cells to the implantable device (1) as compared to regular patterns of micropillars (50). L'invention porte sur un dispositif implantable (1) comprenant une structure en polymère (40) ayant une surface externe tournée vers un tissu environnant lorsque le dispositif implantable (1) est implanté dans un corps de sujet. Au moins une partie de la surface de la structure (40) a un motif semi-aléatoire de micropiliers d'extension (50). Le motif semi-aléatoire de micropiliers (50) sur la surface contribue à des caractéristiques de surface avantageuses du dispositif implantable (1) en termes de réduction de l'adhésion de cellules viables au dispositif implantable (1) par rapport à des motifs réguliers de micropiliers (50).
