Intraocular shunt placement in the suprachoroidal space

a suprachoroidal space and intraocular shunt technology, applied in the field of shunt placement, can solve the problems of trabecular meshwork, open angle glaucoma, retinal damage and blindness, etc., and achieve the effect of reducing or eliminating the risk of hypotony and related side effects, and protecting the integrity of the conjunctiva

Benefits of technology

The present invention is related to devices used for deploying intraocular shunts without using optical apparatus that contacts the eye. One device has a bent portion that slides into the eye and informs the operator that the device is properly positioned. Another device has a flexible shaft that self-guides the shunt to the suprachoroidal space as it is deployed. These devices make the deployment process easier and more accurate.

Problems solved by technology

Build-up of aqueous humor and resulting intraocular pressure may result in irreversible damage to the optic nerve and the retina, which may lead to irreversible retinal damage and blindness.
A common cause of open angle glaucoma is blockage in the trabecular meshwork, the fluid flow pathways that normally drain aqueous humor from the anterior chamber of the eye.
A problem with treating closed angle glaucoma with surgical intervention is that the closed anterior chamber angle prevents an operator from advancing the deployment device into the anterior chamber angle, and thus the device cannot be properly positioned to deploy an intraocular shunt.
Once inserted into the eye, the interaction between the hollow shaft of the deployment device and surrounding eye tissue oftentimes causes the shaft to become stuck in the surrounding eye tissue (due to frictional resistance, for example), which can cause severe eye trauma upon shunt deployment or withdrawal of the shaft from the eye.
Rotation of the deployment device, or portion thereof, causes the portion of the deployment device inserted into the eye to also rotate, thereby loosening the deployment device from the surrounding eye tissue.
Such pressure build-up typically results from particulate partially or fully clogging an entry or an exit port of the shunt.

Embodiment Construction

[0136]The present inventions generally relate to methods for treating closed angle glaucoma that involve using a deployment device that is configured to both re-open a partially or completely closed anterior chamber angle and deploy an intraocular shunt. In certain aspects, some methods involve inserting into an eye a deployment device configured to hold an intraocular shunt, using the device to re-open an at least partially closed anterior chamber angle of an eye, and deploying the shunt from the device.

[0137]FIG. 1 provides a schematic diagram of the general anatomy of the eye. An anterior aspect of the anterior chamber 1 of the eye is the cornea 2, and a posterior aspect of the anterior chamber 1 of the eye is the iris 4. Beneath the iris 4 is the lens 5. The anterior chamber 1 is filled with aqueous humor 3. The aqueous humor 3 drains into a space(s) 6 below the conjunctiva 7 through the trabecular meshwork (not shown in detail) of the sclera 8. The aqueous humor is drained from...

Abstract

Glaucoma can be treated by implanting an intraocular shunt into the eye. Such procedures can employ various deployment devices, shunts, and implantation techniques. A method for treating glaucoma can include injecting a drug into the eye and positioning an intraocular shunt in eye tissue such that the shunt conducts fluid from the anterior chamber to the suprachoroidal space.
