摘要:
An anchor device is described that is adapted to support one or more conductors extending out of an opening in an outer surface of an eye, from a device implanted in the eye to a communications interface. The anchor device comprises a conductor receiving portion including a channel, the conductors being positionable through the channel; and a fixation portion connected to the conductor receiving portion, the fixation portion being adapted to be secured to the outer surface of the eye. The conductor receiving portion is configured to allow movement of the channel and/or conductors relative to the fixation portion. A visual prosthesis comprising the anchor device is also described, along with apparatus and methods for positioning the visual prosthesis or other types of implantable electrical apparatus.
摘要:
A prosthesis is provided comprising a substrate having a distal end and a proximal end; and a plurality of electrodes located at or adjacent the distal end of the substrate. The distal end of the substrate is configured for insertion, via an incision, between first and second tissue layers, such as the sclera and choroid in the eye. The prosthesis tapers in thickness towards the distal end and has a substantially curved provide profile at least on one surface so that the prosthesis can be inserted into position without needing a guide and without causing damage to the tissue or the prosthesis. The prosthesis can include an electrode interface unit located at or adjacent the proximal end of the substrate which locates between the tissue layers. An anchor portion can be provided that extends from the substrate into the incision.
摘要:
A method and apparatus is described for electrically stimulating a patient's retina with an electrode array (32) implanted in the patient's eye, wherein one or more images are captured; at least one line and/or edge in the images is determined (21), a line of electrodes in the electrode array corresponding to a detected line and/or edge is identified (24); and electrical current is applied simultaneously to electrodes of the identified line of electrodes.
