Patent number: 7277759Abstract: A method of recording neural responses reduces the inaccuracy of the recordings caused by nerve adaptation to repeated exposure of stimuli. In one embodiment, a maximum set of X number of successive stimuli are delivered through an electrode and the resulting neural response recorded and, afterwards, the next stimulation must occur through another electrode. This stimulation sequence prevents the same set of nerves from being stimulated too often, which can result in stimulus adaptation and cause measurement inaccuracy. In one embodiment of the invention, a smart software can be employed to provide visual plots of “growth curves”, including real-time calculated datapoints and their confidence intervals, and automatically terminate the recording session upon reaching a pre-set trigger. Alternatively, a human operator can terminate a recording session, based on visual feedback of growth curves, including their real-time calculated datapoints and confidence intervals.Type: GrantFiled: February 4, 2004Date of Patent: October 2, 2007Assignee: Advanced Bionics CorporationInventors: Edward H Overstreet, Guillermo A Calle, Kevin H Hood

Publication number: 20070208394Abstract: A neural stimulation system automatically corrects or adjusts the stimulus magnitude (stimulation energy) in order to maintain a comfortable and effective stimulation therapy. Because the changes in impedance associated with the electrode-tissue interface can indicate obstruction of current flow and positional lead displacement, lead impedance can indicate the quantity of electrical stimulation energy that should be delivered to the target neural tissue to provide corrective adjustment. Hence, a change in impedance or morphology of an impedance curve may be used in a feedback loop to indicate that the stimulation energy needs to be adjusted and the system can effectively auto correct the magnitude of stimulation energy to maintain a desired therapeutic effect.Type: ApplicationFiled: May 10, 2007Publication date: September 6, 2007Applicant: ADVANCED BIONICS CORPORATIONInventors: John King, James Thacker

Patent number: 7263402Abstract: A system and method for rapidly switching stimulation parameters of a Spinal Cord Stimulation (SCS) system increases the number of stimulation parameter sets that may be tested during a fitting procedure, or alternatively, reduces the time required for the fitting procedure. The switching method comprises selecting a new stimulation parameter set, and setting the initial stimulation levels to levels at or just below an estimated perception threshold of the patient. The estimated perception level is based on previous stimulation results. The stimulation level is then increased to determine a minimum stimulation level for effective stimulation, and/or an optimal stimulation level, and/or a maximum stimulation level, based on patient perception.Type: GrantFiled: August 5, 2002Date of Patent: August 28, 2007Assignee: Advanced Bionics CorporationInventors: James R Thacker, John D King, Kerry Bradley

Publication number: 20070179565Abstract: A multichannel cochlear implant system spatially spreads the excitation pattern in the target neural tissue by either: (1) rapid sequential stimulation of a small group of electrodes, or (2) simultaneously stimulating a small group of electrodes. Such multi-electrode stimulation stimulates a greater number of neurons in a synchronous manner, thereby increasing the amplitude of the extra-cellular voltage fluctuation and facilitating its recording. The electrical stimuli are applied simultaneously (or sequentially at a rapid rate) on selected small groups of electrodes while monitoring the evoked compound action potential (ECAP) on a nearby electrode. The presence of an observable ECAP not only validates operation of the implant device at a time when the patient may be unconscious or otherwise unable to provide subjective feedback, but also provides a way for the magnitude of the observed ECAP to be recorded as a function of the amplitude of the applied stimulus.Type: ApplicationFiled: April 6, 2007Publication date: August 2, 2007Applicant: ADVANCED BIONICS CORPORATIONInventors: Edward Overstreet, Leonid Litvak, Michael Faltys

Patent number: 7251530Abstract: Errors in pitch (frequency) allocation within a cochlear implant are corrected in order to provide a significant and profound improvement in the quality of sound perceived by the cochlear implant user. In one embodiment, the user is stimulated with a reference signal, e.g., the tone “A” (440 Hz) and then the user is stimulated with a probe signal, separated from the reference signal by an octave, e.g., high “A” (880 Hz). The user adjusts the location where the probe signal is applied, using current steering, until the pitch of the probe signal, as perceived by the user, matches the pitch of the reference signal, as perceived by the user. In this manner, the user maps frequencies to stimulation locations in order to tune his or her implant system to his or her unique cochlea.Type: GrantFiled: December 9, 2003Date of Patent: July 31, 2007Assignee: Advanced Bionics CorporationInventors: Edward H Overstreet, Leonid M Litvak, William Vanbrooks Harrison

Such battery construction allows the rechargeable battery to be discharged down to zero volts without damage to the battery. The implantable medical device includes battery charging and protection circuitry that controls the charging of the battery so as to assure its reliable and safe operation. A multi-rate charge algorithm is employed that minimizes charging time while ensuring the battery cell is safely charged. Fast charging occurs at safer lower battery voltages (e.g., battery voltage above about 2.5 V), and slower charging occurs when the battery nears full charge higher battery voltages (e.g., above about 4.0 V). When potentially less-than-safe very low voltages are encountered (e.g., less than 2.Type: GrantFiled: April 18, 2003Date of Patent: July 24, 2007Assignees: Advanced Bionics Corporation, Quallion, LLCInventors: Paul M Meadows, Carla Mann Woods, Hisashi Tsukamoto, Joey Chen

Patent number: 7242985Abstract: Contrast between various frequency components of sound is enhanced through a lateral suppression strategy to provide increased speech perception in the electrically stimulated cochlea. A received audio signal is divided into a plurality of input signals, wherein each input signal is associated with a frequency band. A plurality of envelope signals are generated by determining the envelope of each of a plurality of the input signals. At least one of the envelope signals is scaled in accordance with a scaling factor to generate at least one scaled envelope signal. An output signal is generated by combining at least one envelope signal with at least one scaled envelope signal, and the cochlea is stimulated based on the generated output signal. The lateral suppression strategy can be applied to one or more frequency bands using scaled amplitude signals associated with one or more neighboring frequency bands.Type: GrantFiled: December 3, 2004Date of Patent: July 10, 2007Assignee: Advanced Bionics CorporationInventors: Gene Y.

Patent number: 7239920Abstract: A neural stimulation system automatically corrects or adjusts the stimulus magnitude in order to maintain a comfortable and effective stimulation therapy. Auto correction of the stimulus magnitude is linked to the measurement of pressure in the vicinity of the electrode-tissue interface. Because the pressure near the electrode-tissue interface can provide a measure of the electrode contacts' proximity to the neural tissue, and hence quantity of electrical energy delivered to the neural tissue, a change in the measured pressure or pressure morphology indicates that the stimulation energy may need to be adjusted. Hence, changes in pressure provide a feedback mechanism that permit the system to effectively auto correct the stimulus amplitude in order to maintain a desired therapeutic effect.Type: GrantFiled: February 11, 2003Date of Patent: July 3, 2007Assignee: Advanced Bionics CorporationInventors: James R Thacker, Carla Mann Woods
