Patent ID: 8353862

Claim:
A drug delivery system for introducing an implant into the vitreous of an eye, said system comprising: a housing; a tip connected to one end of said housing; a rod implant; a rod stabilizing fluid; a first plunger and a second plunger; a first piston slidably disposed within said housing; a second piston slidably disposed within said first plunger; a first cannula extending from said tip for receiving said rod implant and inserting said rod implant into the vitreous of an eye following movement of said first plunger and a second cannula concentrically disposed within said first cannula; and a chamber within said first plunger, said chamber being defined between said first piston and said second piston, said second cannula being in fluid communication with said chamber; wherein said second cannula is adapted for receiving and ejecting the rod stabilizing fluid from the chamber behind the inserted rod implant upon movement of said second plunger, wherein the rod stabilizing fluid both stabilizes the inserted rod implant and prevents movement of the inserted rod implant as the cannulas are withdrawn from the vitreous of an eye.
