Embodiment Construction

[0034] figure 1 Shown is an intraocular implant 30, constructed in accordance with one embodiment of the present invention, implanted within the globe 10 of the eye. Implant 30 includes a needle 32 and a flanged disc 34 . The plane of flanged disc 34 and tube 32 form an angle corresponding to the angle between the surface of sclera 12 and the axis of insertion of implant 30 . In the area of ​​the incision adjacent to the cornea 16 . The implant 30 is inserted into the sclera 12 of the eyeball 10 and protrudes into the anterior chamber 20 adjacent to the iris 22 . The implant 30 is inserted so that the flanged disc 34 is seated over a surface of the sclera 12 underlying the conjunctiva 18 . Implant 30 may be placed above or below Tenon's capsule (not shown). Those of ordinary skill in the art will understand that the specific location for insertion of the implant 30 is not limited to what is shown, and other suitable locations, such as behind the iris 22, are also possible....

Abstract

An ophthalmic implant for treatment of glaucoma, a delivery device for implanting such an implant, and a method of implanting such an implant. The implant includes a tube having an inlet end, an outlet end, and a tube passage therebetween, and a disk connected to the tube at the outlet end of the tube. The tube passage has a cross-sectional area sufficiently small to inhibit the flow of aqueous humor through the tube passage. The implant provides a bleb of aqueous humor under the conjunctiva so that the bleb and the elasticity of the conjunctiva assist in regulating the flow of aqueous humor through the tube as a function of the IOP. The tube at its inlet end has a beveled surface facing away from the iris and one or more circumferential holes. One or more retention projections are provided for anchoring and may be extended outwardly when the implant is implanted in the eyeball. The disk has an outer rim and one or more inner uprights. The implant is implanted by use of a delivery device comprising a handle and a rodlike instrument, with a tip for insertion into the tube passage of the implant and a retention mechanism for retaining the implant. During implantation, the implant is inserted through a slit in a portion of the conjunctiva which normally lies at a distance away from the intended implantation site.

Description

[0001] This application is a divisional application of the invention patent application with the application number 96195177.X and the invention title "Intraocular Implant, Implantation Device, and Implantation Method". technical field [0002] The present invention generally relates to ocular implants for the treatment of glaucoma, implant devices for implanting such implants, and methods of implanting such implants. Background technique [0003] Glaucoma is an ocular condition characterized by an increase in the intraocular pressure (IOP) of the eye to an abnormal level. A normal eye maintains an appropriate IOP through the circulation of aqueous humor in the eye. Aqueous humor is secreted from the ciliary body, flows through the pupil into the anterior chamber of the eye, and permeates out of the eye through the trabeculae and the Canal of Schlemm. In glaucoma, the drainage channels of the aqueous humor are blocked, the aqueous humor does not flow out of the eyeball at a...
