Abstract
An improved stimulus coil for use in wireless stimulation of biological tissue (e.g., nerves, muscle tissue, etc.) and, in one exemplary implementation, to glaucoma therapy based on the wireless administration of energy to the eye of a mammalian subject (e.g., human, rodent, etc.) to reduce an elevated intraocular pressure (IOP) involving the use of an improved stimulus coil. The improved stimulus coil may be implanted in the eye of a mammalian subject or positioned on the exterior of the eye, such as (by way of example) by being disposed within a contact lens worn by a mammalian subject.
Claims9
A method of reducing elevated intraocular pressure in an eye of a mammalian subject, comprising:
- transmitting an electromagnetic field to a stimulation electrode assembly positioned near an eye of a mammalian subject, the stimulation electrode assembly adapted to stimulate at least one intraocular structure to reduce an elevated intraocular pressure within the mammalian eye by (i) decreasing aqueous humor inflow into an anterior segment of the eye, and (ii) increasing aqueous humor outflow from the anterior segment of the eye, wherein the stimulation electrode assembly includes a plurality of inner electrodes and a plurality of outer electrodes radially spaced apart from the inner electrodes, wherein the plurality of inner electrodes create an inner circular shape and the plurality of outer electrodes create an outer circular shape.
