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.

Reducing elevated intraocular pressure via a stimulation electrode assembly

An arrangement for reducing intraocular pressure includes a pulse signal source, a probe coupling, and at least one electrode. The probe coupling is configured to be supported on a portion of a living eye. The electrodes are supported on the probe coupling. The electrodes are operably coupled to receive a pulse signal from the pulse signal source.

Optical pressure treatment through electrical stimulation

Systems and methods for wireless stimulation of biological tissue (e.g. nerves, muscle tissue, etc.) and, in one exemplary implementation, to therapy for glaucoma 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 a multi-coil wireless power transfer assembly. The multi-coil wireless power transfer assembly may be used alone or in combination with a stimulation coil that can be implanted in the eye of a mammalian subject or within a contact lens worn by a mammalian subject.

High-resolution, selective, and self-optimizing haptic and electrotactile display and methods of use. In an embodiment of a feedback system referenced herein, the feedback system includes a prosthesis configured to be worn by an individual, including at least one prosthesis sensor configured to detect a state or condition in an environment of the at least one prosthesis sensor, and at least one actuator in communication with the at least one prosthesis sensor and configured to receive data relating to the detected state or condition and to stimulate a nerve of the individual; a neural sensor positioned upon or within the individual, configured to detect a neural response relating to the stimulation of the nerve by the at least one actuator; and a processor in communication with at least one of the at least one prosthesis sensor, at least one of the at least one actuator, and the neural sensor.

Stimulus coil and pulse generator for wireless glaucoma therapy

Systems and techniques for wireless implantable devices, for example implantable biomedical devices employed for biomodulation. Some embodiments include a biomodulation system including a non-implantable assembly including a source for wireless power transfer and a data communications system, an implantable assembly including a power management module configured to continuously generate one or more operating voltage for the implantable assembly using wireless power transfer from the non-implantable assembly, a control module operably connected to at least one communication channel and at least one stimulation output, the control module including a processor unit to process information sensed via the at least one communication channel and, upon determining a condition exists, to generate an output to trigger the generation of a stimulus.

System for wireless recording and stimulating bioelectric events

Apparatus and methods for the measurement and transmission of data pertaining to the tissue of an animal. In one embodiment, there is an implantable device that is wirelessly powered and also wirelessly transmits data. Preferably, the implant measures neuromuscular activity.

Wirelessly-powered implantable EMG recording system

Systems and techniques can prevent reflux induced laryngospasm and the pathologies resulting therefrom, including (but not limited to) sudden death in epilepsy (SUDEP) and sudden infant death syndrome (SIDS).

Prevention of reflux induced laryngospasm

Systems and methods for wireless glaucoma therapy involving the administration of energy to an eye of a mammalian subject in a therapeutically effective amount sufficient to (1) decrease the inflow of aqueous humor into the anterior segment of the eye and/or (2) increase the outflow of aqueous humor from the anterior segment of the eye. Systems and methods involve the use of wireless power transfer (WPT) and optional stimulus coils adapted to be positioned on and/or within the eye. A Frensel lens is also disclosed for vision correction, which may be used alone or in combination with the system for wireless glaucoma therapy.

An electronic memory array includes a plurality of memory domains, a current controller, and a selector device. Each memory domain includes a plurality of bit cells. The current controller includes a current controller output electrically connectable to said plurality of memory domains and is configured to control a bit cell current. The selector device is electrically connected to the current controller and the plurality of memory domains. The selector device is configured to selectively electrically connect the current controller output to only a select one of said memory domains, such that the current controller controls only the bit cell current of the bit cells of the select memory domain.
