Title: Apparatus and method for cannulating retinal blood vessels

Abstract: An apparatus and method for safely cannulating a retinal blood vessel isdescribed. The apparatus consists of a micropipette/microcannula,micromanipulator and positioner mounted to a base, which is attached to awrist rest commonly used in eye surgery. The micropipette/microcannula isconnected to tubing such that a medication may be injected through themicropipette/microcannula into the blood vessel or conversely, a smallquantity of material may be removed from a blood vessel. Alternatively, acatheter, wire or stent may be placed through themicropipette/microcannula to treat or diagnose an area remote from theinsertion site. The ability to cannulate a retinal blood vessel should beefficacious in the treatment of vein and artery occlusion, ocular tumorsand other retinal, vascular and optic nerve disorders that would benefitfrom diagnosis and/or treatment.
