Title (EN) Biodegradable medical device for breast reconstruction and/or augmentation
(FR) DISPOSITIF MÉDICAL BIODÉGRADABLE POUR AUGMENTATION ET/OU RECONSTRUCTION MAMMAIRE
Abstract:
(EN) An implantable biodegradable medical device arranged for breast reconstruction and/or augmentation, made of an interconnected porous structured polymeric matrix and belonging to the family of poly(urea urethane)s. The porous structured polymeric matrix of the medical device comprises a plurality of three dimensional channels, drilled by means of heated tools, three‑dimensionally propagating through the polymeric matrix ad interconnected with the porous structure of the polymeric matrix. The polymeric matrix comprises high to-medium molecular weight hydrophobic biodegradable amorphous soft segments polyols, having average molecular weight comprised between 20'000 and 60'000 Da,- hydrophilic polyalkoxide polyols, of average molecular weight comprised between 2'000 and 15'000 Da, and low molecular weight polyisocyanates and polyols, whose average molecular weights range between 15 and 200 Da.
(FR) L'invention concerne un dispositif médical biodégradable implantable conçu pour une augmentation et/ou reconstruction mammaire, constitué d'une matrice polymère à structure poreuse interconnectée, et appartenant à la famille de polyurée-uréthanes. La matrice polymère à structure poreuse du dispositif médical comprend une pluralité de canaux tridimensionnels, percés au moyen d'outils chauffés, se propageant tridimensionnellement à travers la matrice polymère et interconnectés avec la structure poreuse de la matrice polymère. La matrice polymère comprend des polyols en segments souples amorphes biodégradables hydrophobes à masse moléculaire élevée-moyenne, ayant une masse moléculaire moyenne comprise entre 20 000 et 60 000 Da, des polyols polyalcoxydes hydrophiles ayant une masse moléculaire moyenne comprise entre 2 000 et 15 000 Da, et des polyisocyanates et polyols de faible masse moléculaire, dont les masses moléculaires moyennes sont comprises entre 15 et 200 Da.
