IMPLANTABLE DRUG DELIVERY DEVICE AND A SYSTEM & METHOD FOR DEPLOYMENT OF SUCH DEVICES

摘要

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.

1. A drug delivery device comprising:
(a) a core; 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.
