1. A drug delivery device comprising:
(a) a core formed from elastomeric material; and
(b) a sleeve deployed around said core, said sleeve having first and second portions inwardly inverted and having elastic properties such that, when a fluid is introduced between said core and said sleeve, said sleeve inflates to form a reservoir with a pressure of said fluid pressing said inwardly-inverted portions against said core, wherein at least one fluid release passageway extends between said core and at least one of said inwardly-inverted portions for slow release of the fluid,
and wherein a proximal end of the core is configured as a septum to allow for injection of the fluid into the reservoir.
