Patent number: 10543372Abstract: The present disclosure provides a method of forming a hermetically sealed enclosure that comprises a diamond material. The method comprises providing first and second enclosure components comprising the diamond material and having first and second recesses, respectively, at edge portions. At least one of the first and second enclosure components has a cavity. The enclosure components have respective contact surfaces at the first and second recesses and are shaped such that an outer channel is formed by the co-operation of the first and second recesses when the first and second enclosure components are contacted at the contact surfaces to form the enclosure. The method further comprises bonding a first type of material to at least surface portions of the first and second recesses of the first and second enclosure components, respectively.Type: GrantFiled: October 28, 2015Date of Patent: January 28, 2020Assignees: The University of Melbourne, National ICT Australia LimtiedInventors: Steven Prawer, Kumaravelu Ganesan, David Garrett, Nicholas Apollo, Alastair Stacey, Mathilde Escudie, Hamish Meffin, Samantha Lichter

Patent number: 9517345Abstract: The present disclosure relates to a method for determining stimulation parameters for a neuroprosthetic device performed by a processor of the device. Based on (i) a desired spatial pattern of neural activity, the processor determines stimulation parameters for an array of electrodes of the neuroprosthetic device. The processor determines the stimulation parameters such that a difference between (i) the desired spatial pattern of neural activity and (ii) an estimated spatial pattern of neural activity is optimised. The estimated spatial pattern of neural activity is an estimate of a response of a target neural tissue to being stimulated by the neuroprosthetic device based on the stimulation parameters. This method allows higher resolution stimulation and allows electrode arrays with higher electrode density to be usefully employed.Type: GrantFiled: January 28, 2014Date of Patent: December 13, 2016Assignee: NATIONAL ICT AUSTRALIA LIMITEDInventors: Hamish Meffin, Anthony Burkitt, David Grayden, Behman Tayahori, Elma O'Sullivan Greene

Publication number: 20150245946Abstract: A method of positioning an intraocular device at an intraocular position is provided. The method comprises providing a first and a second element selected such that a magnetic force attracts the first element and the second element to each other. The method also comprises positioning the first element in a suprachoroidal space of an eye and positioning the intraocular device in an intraocular space at a portion of tissue of the eye. The method further comprises positioning the second element in the intraocular space of the eye. The first element, the second element and the intraocular device are positioned such that the portion of the tissue of the eye and at least a portion of the intraocular device are positioned between the first and second elements such that the magnetic force at least contributes to securing the intraocular device at the portion of the tissue of the eye.Type: ApplicationFiled: May 15, 2015Publication date: September 3, 2015Inventors: Kate Fox, David Garrett, Kumaravelu Ganesan, Hamish Meffin, Steven Prawer
