Abstract
Abstract An apparatus and method for safely cannulating a blood vessels, including but not limited retinal blood vessels, is described. In one embodiment, the apparatus can consist of a micropipette/microcannula, micromanipulator and positioner mounted to a base, which is attached to a wrist rest commonly used in eye surgery. The micropipette/microcannula is connected to tubing such that a medication may be injected through the micropipette/microcannula into the blood vessel or conversely, a small quantity of material may be removed from a blood vessel. Alternatively, a catheter, wire or stent may be placed through the micropipette/microcannula to treat or diagnose an area remote from the insertion site. The ability to cannulate a retinal blood vessel should be efficacious in the treatment of vein and artery occlusion, ocular tumors and other retinal, vascular and optic nerve disorders that would benefit from diagnosis and/or treatment. In another embodiment, a self-sealing needle is provided which allows the perforation of a blood vessel or other structure and the minimization of hemorrhaging when the needle is withdrawn from the blood vessel/structure. Another embodiment discloses an ocular implant needle.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
73 words
A needle comprising: a relatively rigid hollow body member having a single angled first end to define a relatively sharp beveled tip, a second end connected to and in internal communication with a delivery device, an internal passageway and an externally disposed aperture, and a marking device disposed on said body member; wherein said aperture disposed between said marking device and said second end and is accessible to the user while in use.
Claim 2
Dependent Claim
73 words
A needle comprising: a relatively rigid hollow body member having a single angled first end to define a relatively sharp beveled tip, a second end connected to and in internal communication with a delivery device, an internal passageway and an externally disposed aperture, and a marking device disposed on said body member; wherein said aperture disposed between said marking device and said second end and is accessible to the user while in use.
Claim 3
Dependent Claim
14 words
The needle of claim 1 wherein the body member is one-piece and substantially straight.
Claim 4
Dependent Claim
42 words
The needle of claim 2 wherein the size of said body member along with said beveled tip causing an incision at the perforation site which is self sealing upon removal of said body member including said beveled tip from the perforation site.
Claim 5
Dependent Claim
12 words

Claim 7
Dependent Claim
15 words
The needle of claim 1 wherein said body member is constructed from a biocompatible material.
Claim 8
Dependent Claim
12 words
The needle of claim 1 wherein said biocompatible material is stainless steel.
Claim 9
Dependent Claim
11 words

Claim 12
Dependent Claim
119 words
An ocular implant needle comprising: a relatively rigid hollow body member having a single angled open first end to define a relatively sharp beveled tip and a second end connected to and in internal communication with a device for delivering an ocular implant, said body member defining at least one externally disposed aperture therein; and a flange disposed on said body member approximate to said first end of said body member; said at least one externally disposed aperture disposed between said flange and said second end of said body member; wherein said aperture is accessible to the user while in use and is sized to prevent the ocular implant traveling through said body member from escaping through said aperture.
Claim 13
Dependent Claim
119 words
An ocular implant needle comprising: a relatively rigid hollow body member having a single angled open first end to define a relatively sharp beveled tip and a second end connected to and in internal communication with a device for delivering an ocular implant, said body member defining at least one externally disposed aperture therein; and a flange disposed on said body member approximate to said first end of said body member; said at least one externally disposed aperture disposed between said flange and said second end of said body member; wherein said aperture is accessible to the user while in use and is sized to prevent the ocular implant traveling through said body member from escaping through said aperture.
