Benefits of technology

The invention provides an ocular implant with spines and a frame that can be placed within a human eye to treat glaucoma. The spines have a unique shape that undulates as they extend between the first and second spines in the implant. The frame has struts that also undulate as they extend between the spines. The implant has a constant radius and thickness as it extends between the spines. The invention also provides an ocular implant with a first opening and a second opening, and a therapeutic agent can be deposited on the frame and spines. The technical effects of the invention include improved outflow of aqueous humor, reduced intraocular pressure, and improved treatment of glaucoma.

Problems solved by technology

Researchers have theorized prolonged exposure to high intraocular pressure causes damage to the optic nerve that transmits sensory information from the eye to the brain.
This damage to the optic nerve results in loss of peripheral vision.
As glaucoma progresses, more and more of the visual field is lost until the patient is completely blind.

Abstract

An ocular implant having a first spine; a second spine; a first strut extending in an axial direction Z between the first spine and the second spine; a second strut extending in an axial direction Z between the first spine and the second spine; wherein an angular dimension θ of a first edge of each strut undulates as the strut extends in the axial direction Z between the first spine and the second spine; and wherein a radius r of an outer surface of each strut remains substantially constant as the strut extends the axial direction Z between the first spine and the second spine.
