Abstract: In some examples, the disclosure relates to system, devices, and techniques for delivering electrical stimulation therapy to treat patient disorders. In some example, the disclosure is directed to a method including controlling, using processing circuitry, the delivery of an electrical stimulation therapy to a patient via a medical device, wherein the electrical stimulation therapy includes a plurality of bi-phasic pulses, each pulse of the di¬phasic pulses including a first phase followed by a second phase, and wherein the plurality 7 of bi-phasic pulses are configured to substantially block transmission of neural activity? along nerve fibers.

Abstract: Among other things, a stimulation strategy can be customized for a cochlear implant implanted in an individual by testing at least a pair of electrodes selected from an array of electrodes associated with the cochlear implant. Testing the at least a pair of electrodes includes applying a first stimulation to the at least a pair of electrodes using a first pair of pulse trains that are out of phase, and applying a second stimulation to the at least a pair of electrodes using a second pair of pulse trains that are out of phase. A determination is made on whether the at least a pair of electrodes stimulate the same neural population based on a sensitivity of the individual to detect a perceived difference between the two pairs of pulse trains. The one or more electrodes of the array of electrodes are selectively stimulated based on the determination.

Testing the at least a pair of electrodes includes applying a first stimulation to the at least a pair of electrodes using a first pair of pulse trains that are in phase, and applying a second stimulation to the at least a pair of electrodes using a second pair of pulse trains that are out of phase. A determination is made on whether the at least a pair of electrodes stimulate the same neural population based on a sensitivity of the individual to detect a perceived difference between the two pairs of pulse trains.

Abstract: An exemplary signal processing unit includes a plurality of filters configured to divide an audio signal into a plurality of analysis channels, one or more detection stages configured to detect an energy level within each of said analysis channels, a selection stage configured to select one or more of said analysis channels for presentation to a patient, a synthesizer stage configured to synthesize said selected analysis channels, and a mapping stage configured to map said selected analysis channels to a number of stimulation channels within an implantable cochlear stimulator, wherein a total number of said analysis channels is greater than a total number of said stimulation channels.

Abstract: Methods and systems of presenting an audio signal to a cochlear implant patient include dividing the audio signal into a plurality of analysis channels, detecting an energy level within each of the analysis channels, selecting one or more of the analysis channels for presentation to the patient, synthesizing the selected analysis channels, and mapping the synthesized analysis channels to one or more stimulation channels.

Abstract: A method for reducing the effects of decreased resolution in a cochlear implant worn by an individual includes 1) determining the value of the individual's resolution region, 2) analyzing a plurality of dominant components within a sound signal, 3) removing a component that has lesser associated energy of two or more components that are within the resolution region of one another, thereby producing a sound signal with a reduced pattern of components, and 4) transmitting the reduced pattern signal to an array of electrodes associated with the cochlear implant.
