Publication number: 20230372712Abstract: Newly implanted cochlear implant recipients have highly individual and variable patterns of increasing tolerance and recognition of stimulus. Disclosed techniques include a series of self-administered fittings. During an initial clinical fitting, the recipient is given a basic map. Working at their own pace, the recipient can perform self-administered percept exercises that test the recipient's growing capacity to perceive stimulus quality. The results of the exercises are analyzed and compared with reference data. A clinical alert is generated when the recipients data pattern conforms to a predetermined criteria that indicates the recipient can benefit from a clinical visit because their performance is of a sufficiently stable nature. Optionally, the results of the exercises can be combined with trained clinical data, to make incremental map adjustments over time as the recipient is adapting to cochlear stimulation at their own pace.Type: ApplicationFiled: September 2, 2021Publication date: November 23, 2023Inventors: Bastiaan VAN DIJK, Obaid ur Rehman QAZI

Publication number: 20200330764Abstract: Presented herein are techniques to control the spread of current beyond, in an apical direction, a predetermined location/point in the cochlea. As a result, the techniques presented herein create a protected apical zone at an apical side of the predetermined location for undisturbed acoustic temporal coding (i.e., an apical region of the cochlea in which the voltage fields from delivered current signals are nulled, minimized, or otherwise controlled in order to eliminate, reduce, or otherwise limit electro-acoustic interactions that could negatively affect remaining low-frequency hair cells).Type: ApplicationFiled: December 7, 2018Publication date: October 22, 2020Inventors: Zachary Mark Smith, Bastiaan Van Dijk

Patent number: 10449357Abstract: Techniques for automatically analyzing neural activity within a target neural region. In one example, electrical stimulation is applied to the target neural region at an initial current level that approximates a typical threshold-Neural Response Telemetry (NRT) level. An NRT measurement of neural activity within the target neural region in response to the stimulation is recorded. A machine-learned expert system, which is configured with a decision tree that includes at least two levels of nodes which consider parameters relating to the NRT measurement, respectively, is utilized to predict, based on one or more features of the neural activity, whether the NRT measurement includes a neural response or does not include a neural response.Type: GrantFiled: July 5, 2017Date of Patent: October 22, 2019Assignee: Cochlear LimitedInventors: Andrew Botros, Matthijs Killian, Bastiaan van Dijk

Patent number: 10225671Abstract: Presented herein are techniques for providing tinnitus relief to recipients of a hearing prosthesis. In accordance with embodiments presented herein, a hearing prosthesis comprises a tinnitus relief system that is configured to generate a tinnitus masker signal that comprises a plurality of discrete (separate) components. The tinnitus relief system is configured to inject the components of the tinnitus masker signal directly into a sound processing path so that the masker components are combined with different processed portions of a channelized sound signal. The channelized sound signal and the components of the tinnitus masker signal are used to generate one or more output signals for use in compensation of a hearing loss of a recipient of the hearing prosthesis.Type: GrantFiled: May 27, 2016Date of Patent: March 5, 2019Assignee: Cochlear LimitedInventors: Michael Goorevich, Phyu Phyu Khing, Matthijs Johannes Petrus Killian, Bastiaan Van Dijk
