A sensor system comprises a permselective medium positionable to contact a fluid in a microchannel, an arrangement of electrodes arranged to generate an electric field across the permselective medium, an ion concentration sensing system having a sensing element configured to provide sensing signals indicative of a local ion concentration pattern, and a signal processor for analyzing a sensing signal received from the ion concentration sensing system to determine at least one flow parameter characterizing the flow.

System and method for measuring flow

Apparatus is provided including an implantable retinal stimulator, for implantation on a retina of an eye, and including (i) an electrode array including electrodes; (ii) a plurality of photosensors; and (iii) driving circuitry, configured to drive the electrodes to apply currents to the retina. The apparatus further includes an interface member disposed at an outer surface of the implantable retinal stimulator, e.g., a peripheral member surrounding at least a portion of the implantable retinal stimulator. The apparatus additionally includes a frame, (i) shaped and sized to couple to the peripheral member and to surround the implantable retinal stimulator at least in part, and (ii) shaped to define at least a first anchoring element receiving portion. An anchoring element is shaped and sized to be positioned in the anchoring element receiving portion and to penetrate scleral tissue of the subject. Other applications are also described.

Retinal implant fixation

A method is provided for implanting, in an eye, apparatus having an electrode array including stimulating electrodes shaped to define distal tips protruding from the array, a plurality of photosensors, and driving circuitry, configured to drive the electrodes to apply currents to the retina. The method includes removing a lens of the eye and a vitreous body of the eye, creating a corneoscleral incision and inserting the apparatus through the corneoscleral incision into a vitreous cavity of the eye. During the inserting, an orientation of the distal tips is maintained pointing towards a cornea of the eye. Subsequently to the inserting, the apparatus is rotated such that the distal tips point towards a macula of the eye. Subsequently to the rotating, the apparatus is positioned epi-retinally, such that the distal tips of the electrodes penetrate the retina. Other applications are also described.
