摘要:
An implantable device (1) for scheduled intraocular drug delivery comprising at least two hollow solids inscribed one into the other, where the walls (2, 3, 4) of said at least two hollow solids are made of biodegradable material based on magnesium, and where the at least two hollow solids inscribed one into the other delimit a volume, called core (7), inside the innermost of the hollow solids and one or more volumes, called crowns (5, 6), comprised between the innermost hollow solid and the hollow solid at the exterior thereof, where the core and the at least one crown are adapted to house doses of at least one active ingredient, whereby the walls are impermeable continuous walls which become permeable as a function of the post-implantation time of said device.
