Abstract
A drug delivery device is formed from an elastic sleeve deployed around a core, with first and second edge portions inwardly inverted. When a fluid is introduced between the core and the sleeve, the sleeve inflates to form a reservoir with a pressure of the fluid pressing the inwardly-inverted extremities portions against the core. The device is preferably anchored by providing a stem of conformable material which is depressed by pressure applied by adjacent edges of a layer of tissue to achieve tissue-wedged anchoring of the device.
Claims17
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.
