Patent number: 10933232Abstract: 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.Type: GrantFiled: July 25, 2018Date of Patent: March 2, 2021Assignee: The Bionics Institute of AustraliaInventors: Christopher Edward Williams, Joel Villalobos Villa, Owen Burns

Publication number: 20190308018Abstract: The present disclosure relates to visual prosthesis apparatus including an implantable device having a substrate and a plurality of electrodes located in or on the substrate, the substrate adapted to be implanted at least partially in an eye of a patient. A first inductor is included in the implantable device, for example by encapsulating an inductor coil in the substrate or on an associated lead or anchor device. In some instances, the electrodes in the substrate may partially provide the first inductor. A second inductor is adapted to locate externally to the eye and inductively couple with the first inductor. A processor is adapted to determine a direction of movement of the eye based on changes in electrical current induced in one of the first and second inductors due to relative movement of the first and second inductors.Type: ApplicationFiled: June 6, 2017Publication date: October 10, 2019Inventors: Matthew Alexander Petoe, Christopher Edward Williams, Rodney Millard, Joel Villalobos, Peter Misha Seligman

Patent number: 8996119Abstract: 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 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.Type: GrantFiled: October 23, 2013Date of Patent: March 31, 2015Assignee: The Bionics Institute of AustraliaInventors: Christopher Edward Williams, Penelope Jayne Allen, Joel Villalobos Villa
