Generating More Than One Signal Patents (Class 607/66)
  • Patent number: 12102827
    Abstract: This disclosure relates to implantable neuro stimulation devices with a feedback loop to control an amount of energy delivered into a neural tissue based on a measured evoked neural response. Stimulation electrodes deliver stimulation energy to neural tissue. A microprocessor performs closed-loop control of the stimulation energy based on a feedback signal that is indicative of an evoked neural response. A supervisor is connected to the feedback signal and detects malfunction of the stimulator based on the feedback signal. The supervisor is also connected to the stimulator to provide a status signal to the stimulator and changes the status signal to indicate malfunction upon detecting malfunction based on the feedback signal. The microprocessor adjusts the control of the stimulation energy in response to the status signal from the supervisor indicating malfunction.

  • Patent number: 12011591
    Abstract: Transcranial electrostimulation systems and methods are contemplated in which a high current level, charge balanced alternating current electrical signal is generated for delivery to the occipital region of a patient's brain. By stimulating the brain with a charged balanced stimulation current with a stimulation current envelope defining one or more series of pulses at particular frequencies and durations designed to evoke metabolic response in the neurons, significant improvements in efficacy and reductions in patient discomfort may be achieved relative to earlier methods of transcranial electrical stimulation, especially those in which result in a resultant rectified direct current component being administered to the patient.

  • Patent number: 11895745
    Abstract: A power supply may provide a constant source of DC power through a first inductor-capacitor network, across a two-line conductor, and through a second inductor-capacitor network to a remote load. A modulator at the supply may modulate a carrier frequency with an information signal containing control data and may pass a modulated signal to the load via the conductor with the DC power. At the load, a demodulator may extract the control data, and operation of the load, such as a bank of LEDs subjected to dimming, may be modified based on the control data. The inductor-capacitor networks enable decoupling of the DC power and data for simple and low-cost implementations at comparatively low frequencies. In examples, the carrier frequency is at least 10 times the rate of the information signal yet below typical communication frequencies such as 525 KHz.

  • Patent number: 9731133
    Abstract: Methods for systematically testing a plurality of therapy programs in a spinal cord modulation system, and associated systems are disclosed. A representative method comprises loading a plurality of therapy programs into a signal generator, wherein individual therapy programs include parameters specifying electrode configuration, signal amplitude, and/or signal frequency. The programs are automatically activated for an automatically instructed period of time. The method includes automatically changing from one therapy program to another after the instructed period of time. The patient is queried for patient input corresponding to the therapy programs. The patient input is received via a remote. The patient input is correlated with a corresponding time of day and recorded in the signal generator. Thereafter, the patient input is retrieved from the signal generator.

  • Patent number: 9566433
    Abstract: A medical stimulation device such as a cochlear implant configured to provide stimulation of one or more spatially-restricted contiguous portion(s) of the spiral array of auditory nerve fibers in the cochlear (“discrete stimulation regions”). Each discrete stimulation region is defined by the constructive and/or destructive interference of stimulating and limiting signals simultaneously applied to electrode channels of an implanted electrode array, the stimulating and limiting signals being determined based upon transimpedance measurements of intracochlear electrode channels of the implanted electrode array representing specific spread functions of an individual recipient. The stimulating signal is preferably applied through a targeted electrode channel; that is, one or more successive electrodes which is/are adjacent to the discrete stimulation region.

  • Patent number: 9352156
    Abstract: Neurostimulation systems and methods for providing therapy to a patient suffering from a symptom of a disease that latently responds to electrical stimulation therapy are provided. First electrical stimulation energy is conveyed to or from a tissue region of the patient in accordance with a first set of stimulation parameters, thereby affecting the symptom. A predetermined period of time estimated for the symptom to resolve in response to electrical stimulation therapy is allowed to elapse. Second electrical stimulation energy is conveyed to or from the tissue region in accordance with a second set of stimulation parameters different from the first set of stimulation parameters.

  • Patent number: 9259588
    Abstract: An external control device for use with a neurostimulator coupled to electrodes. The external control device comprises a user interface configured for receiving input from a user, and including a display screen configured for displaying graphical representations of the electrodes. The external control device further comprises a controller/processor configured for, in response to the input from the user, linking a subset of the electrodes together, and globally assigning at least one of the same stimulation amplitude value and same on/off state to each of the electrodes. The controller/processor may also be configured for, in response to the input from the user, assigning at least one stimulation parameter value to one of the electrodes, copying/cutting the at least one stimulation parameter value from the one electrode, and pasting the at least one stimulation parameter value to the other electrode and modifying current values of other electrodes to maintain 100% current.

  • Patent number: 9192762
    Abstract: A therapeutic micro-current delivery device includes a first electrode in electrical contact with a user at a first user location, a second electrode in electrical contact with the user at a second user location, a power source operable to provide a first voltage potential at the first electrode and a second voltage potential at the second electrode, and a micro-current control circuit in electrical communication with the first electrode, second electrode and power source. Electrical contact of the first electrode at the first user location and electrical contact of the second electrode at the second user location completes an electrical circuit. The micro-current control circuit generates a micro-current Iramped through a user between the first location and the second location that increases from a start current Istart to an end current Iend over a rise time trise. Oral care devices and micro-current control methods are also disclosed.

  • Publication number: 20150134028
    Abstract: The present disclosure involves a method of generating different stimulation waveforms as a part of sacral nerve stimulation therapy. A first stimulation waveform having a first stimulation waveform characteristic is generated. The first stimulation waveform is delivered to a first body part of a patient at least in part via a first channel. A second stimulation waveform having a second stimulation waveform characteristic is generated. The second stimulation waveform characteristic is different from the first stimulation waveform characteristic. The second stimulation waveform is delivered to a second body part of the patient at least in part via a second channel that is separate and independent from the first channel. The first body part and second body part correspond to different organs or different types of nerves.

  • Publication number: 20150088213
    Abstract: A method and apparatus to detect anomalies in the conductors of leads attached to implantable medical devices based on the dynamical electrical changes these anomalies cause. In one embodiment, impedance is measured for weak input signals of different applied frequencies, and a conductor anomaly is detected based on differences in impedance measured at different frequencies. In another embodiment, a transient input signal is applied to the conductor, and an anomaly is identified based on parameters related to the time course of the voltage or current response, which is altered by anomaly-related changes in capacitance and inductance, even if resistance is unchanged. The method may be implemented in the implantable medical device or in a programmer used for testing leads.
