Patent number: 7317944Abstract: A system and method for preserving temporal and spatial resolution in complex sounds for poor performing patients having high stimulation thresholds is described. The system and method employs two or more adjacent electrode contacts to deliver concurrent stimulation. This concurrent delivery of stimuli creates a high current field intensity that overlaps between individual current fields generated by the two or more adjacent electrodes and which individual fields are summed to create an overlapping field that has a higher current field intensity than a single current emanating from an individual electrode. The use of this method reduces or eliminates the need to increase either the stimulus current amplitude or to increase the pulse width, both of which may cause loss of system resolution, i.e., loss of fine structure information that is used to resolve complex sounds such as music.Type: GrantFiled: July 8, 2004Date of Patent: January 8, 2008Assignee: Advanced Bionics CorporationInventor: Edward H Overstreet

Patent number: 7317945Abstract: The present invention provides a cochlear stimulation system and method for capturing and translating fine time structure (“FTS”) in incoming sounds and delivering this information spatially to the cochlea. The system comprises a FTS estimator/analyzer and a current navigator. An embodiment of the method comprises analyzing the incoming sounds within a time frequency band, extracting the slowly varying frequency components and estimating the FTS to obtain a more precise dominant FTS component within a frequency band. After adding the fine structure to the carrier to identify a precise dominant FTS component in each analysis frequency band (or stimulation channel), a stimulation current may be “steered” or directed, using the concept of virtual electrodes, to the precise spatial location (place) on the cochlea that corresponds to the dominant FTS component. This process is simultaneously repeated for each stimulation channel and each FTS component.Type: GrantFiled: November 13, 2003Date of Patent: January 8, 2008Assignee: Advanced Bionics CorporationInventors: Leonid M. Litvak, David A. Krubsack, Edward H. Overstreet
