TRABECULAR MESHWORK STIMULATION DEVICE
An implantable device for mechanically stimulating the trabecular meshwork is disclosed. The device is implanted in the eye adjacent the trabecular meshwork. The device imparts mechanical stimulating in the form of vibrations or movement to the trabecular meshwork. The imparted mechanical stimulation causes the trabecular meshwork to move in a manner that produces a pumping action to remove aqueous from the anterior chamber of the eye.
1 . A method of treating glaucoma comprising:
imparting vibrations to the trabecular meshwork from within an eye to produce a pumping action that removes aqueous from an anterior chamber of the eye.
2 . A method of treating glaucoma comprising:
providing a device that produces mechanical vibrations;
placing the device in an eye adjacent a trabecular meshwork; and
mechanically stimulating the trabecular meshwork with the vibrations.
3 . The method of claim 2 wherein a frequency of the vibrations is varied.
4 . The method of claim 2 wherein an amplitude of the vibrations is varied.
5 . The method of claim 2 wherein placing the device adjacent the trabecular meshwork further comprises:
injecting the device through a corneal incision.
6 . The method of claim 2 wherein providing a device that produces mechanical vibrations further comprises:
providing a device with a mass-spring system, the mass-spring system with a resonance that amplifies natural fluctuations in the eye.
7 . The method of claim 6 wherein the natural fluctuations in the eye are selected from the group consisting of: movement of the body, movement of the eye, blinking, blood flow, aqueous drainage, and pressure changes.
8 . The method of claim 2 wherein providing a device that produces mechanical vibrations further comprises:
providing a device with actuator to produce the vibrations.
9 . The method of claim 2 wherein mechanically stimulating the trabecular meshwork produces movement in the trabecular meshwork that acts to pump aqueous from the eye.
10 . The method of claim 2 wherein mechanically stimulating the trabecular meshwork produces a pumping action in the trabecular meshwork that removes aqueous from the eye.
11 . A device implantable in an eye, the device comprising:
a supporting structure configured to be implanted in an anterior chamber of an eye and reside adjacent a trabecular meshwork of the eye; and
a vibrating structure carried on or integrated with the supporting structure, the vibrating structure configured to impart mechanical stimulation to the trabecular meshwork.
12 . The device of claim 11 wherein the supporting structure is a flexible ring.
13 . The device of claim 11 wherein the supporting structure is a haptic of an intraocular lens.
14 . The device of claim 11 wherein the vibrating structure is a mass-spring system.
15 . The device of claim 14 wherein the mass-spring system is configured with a resonance that amplifies natural fluctuations in the eye.
16 . The device of claim 15 wherein the natural fluctuations in the eye are selected from the group consisting of: movement of the body, movement of the eye, blinking, blood flow, aqueous drainage, and pressure changes.
17 . The device of claim 11 wherein the vibrating structure is an actuator.
18 . The device of claim 17 wherein the actuator is programmable, allowing for customization of:
an on/off state;
a vibration amplitude; and
a vibration frequency.
19 . The device of claim 17 wherein the actuator is driven by an external electromagnetic/magnetic device.
