Patent number: 8571669Abstract: A medical device includes an array of electrodes, configured for implantation in contact with tissue in an eye of a living subject. Driver circuitry is configured to drive the electrodes in an alternating pattern, such that different groups of the electrodes are driven to stimulate the tissue during different, predetermined respective time periods. A power sensor, may be coupled to deactivate a first group of the electrodes when the available electrical power drops below a predetermined threshold, while a second group of the electrodes remains active. Other embodiments are also described.Type: GrantFiled: February 24, 2011Date of Patent: October 29, 2013Assignee: Nano-Retina, Inc.Inventors: Tuvia Liran, Ra'anan Gefen

Patent number: 8442641Abstract: Apparatus for use with an external non-visible light source is provided. The apparatus comprises an intraocular device configured for implantation in a human eye, and comprising an energy receiver. The energy receiver is configured to receive light emitted from the external non-visible light source, and extract energy from the emitted light for powering the intraocular device. The intraocular device is configured to regulate a parameter of operation of the intraocular device based on a modulation of the light emitted by the external non-visible light source and received by the energy receiver. Other embodiments are also described.Type: GrantFiled: May 9, 2011Date of Patent: May 14, 2013Assignee: Nano-Retina, Inc.Inventors: Yosef Gross, Shai Vaingast, Ra'anan Gefen

Patent number: 8428740Abstract: Apparatus is provided including an external device including, a mount, which is placed in front of an eye of a subject. A power source is coupled to the mount and emits energy toward the eye. An intraocular device is implanted entirely in the subject's eye, and includes a control unit, a plurality of stimulating electrodes, and an energy receiver, which receives the energy from the power source and generates a voltage drop in response. A plurality of photosensors detect photons and generate a signal in response. Driving circuitry is coupled to the energy receiver and to the photosensors, and drives the electrodes to apply electrical charges to a retina in response to the signals from the photosensors. The external device modulates the emitted energy, and the control unit demodulates the modulated energy to regulate an operation parameter of the intraocular device. Other embodiments are also described.Type: GrantFiled: August 6, 2010Date of Patent: April 23, 2013Assignee: Nano-Retina, Inc.Inventors: Ra'anan Gefen, Tuvia Liran

Patent number: 8150526Abstract: Apparatus is provided, including an external device, including a mount, which is placed in front of an eye of a subject. A laser is coupled to the mount and configured to emit toward the eye radiation that is outside of 380-750 nm. A partially-transparent mirror is coupled to the mount. An intraocular device is implanted entirely in the subject's eye, and includes a plurality of stimulating electrodes, and an energy receiver, which receives the radiation from the laser and generates a voltage drop in response thereto. A plurality of photosensors detect photons and generate a signal in response thereto. Driving circuitry is coupled to the energy receiver and to the photosensors, and receives the signals from the photosensors and utilizes the voltage drop to drive the electrodes to apply currents to the retina in response to the signals from the photosensors. Other embodiments are also described.Type: GrantFiled: February 9, 2009Date of Patent: April 3, 2012Assignee: Nano-Retina, Inc.Inventors: Yossi Gross, Shai Vaingast
