  • Patent number: 8750986
    Abstract: A method and neurostimulation control system for programming electrodes disposed adjacent tissue of a patient. The electrodes are initially assigned to a plurality of electrode subsets to be evaluated. A pair of immediately neighboring ones of the electrode subsets is determined, and merged into a new electrode subset that includes all electrodes in the pair of immediately neighboring electrode subsets. The new electrode subset is included within the plurality of electrode subsets to be evaluated, while the pair of immediately neighboring electrode subsets is excluded from the plurality of electrode sets to be evaluated. These steps are repeated until all the electrode subsets have been merged into a single electrode subset. A clustering relationship of the electrodes is identified, and the electrodes are programmed based on the identified clustering relationship of the electrodes.

  • Patent number: 8690789
    Abstract: Methods and systems for mapping a physiological signal into clinical guideline parameters are disclosed. A physiological signal having a characteristic that may represent an anomaly is received and mapped to a clinical guideline condition space. Probabilities are determined that the mapped signal with which the anomaly may be associated represents a first clinical guideline condition corresponding to a referral indication or a second clinical guideline condition corresponding to an absence of the referral indication. The determined probability is presented and a referral decision is made responsive to the determined probability that the anomaly is associated with the first clinical guideline condition.

  • Patent number: 8688205
    Abstract: An electrocardiogram (ECG) chart device and method capable of easily assisting with the diagnosis of heart disease. Hexagonal radar charts displayed on a screen act as indicators of feature values corresponding to data obtained from each of 12 electrode leads and correlated with the related portions of the heart. For example, a (V1, V2) lead is an indicator of a right ventricle. Each of the radar charts is schematically arranged to correspond with the related portion of the heart. Each vertex of the hexagonal radar charts acts as an indicator of the recognized value. More specifically, each vertex of the radar chart is based on a value obtained by extracting a waveform critical point, a waveform start point, a waveform end point, or the like, of constituent elements of the ECG waveform as the P wave, the Q wave, the R wave, the S wave, the ST segment, the T wave, or the like. Therefore, a user of the ECG radar chart device can intuitively and easily carry out interpretation of ECG data.

  • Patent number: 8626306
    Abstract: In a visual prosthesis or other neural stimulator it is advantageous to provide non-overlapping pulses in order to provide independent control of brightness from different electrodes. Non-overlapping pulses on geographically close electrodes avoid electric-field interaction which leads to brightness summation or changes in the shape and area of percepts. It is advantageous to apply pulses to nearby electrodes in a way that the currents do not overlap in time at all. The new finding is that even a small amount of separation in time results in a significant improvement with a time separation as small as 0.225 msec. ‘Nearby’ is defined as within a few millimeters of each other.

  • Patent number: 8612015
    Abstract: A method of making a custom mold and the custom mold itself having a first layer, a second layer, and a tail that are formed around the bulging area of an implantable medical device (IMD) are presented. The moldable material during hardening is flattened to form a docking platform for the flat planar bottom of an external antenna. The final apparatus of an antenna support may have all the custom contours of the patient's body around the implanted IMD. An optional tape patch and/or bandage may help maintain a proper placement of the external antenna over the IMD depending on amount of mobility the patient wishes to have during charging. An alternate embodiment uses magnets to secure an external antenna over a metallic segment of an IMD.

  • Patent number: 8606363
    Abstract: A method is disclosed for efficient multiplexing of a plurality of electrodes in a nerve stimulator using improved, predetermined, regular, repeatable geometric patterns arranged in a predetermined mosaic to form a desired array. Multiple electrodes within said array are addressed by the nerve stimulator as being a stimulating electrode by an instruction specifying a single identifier, indicating a position within each regular geometric pattern. As such, each electrode within the array, maintaining the specified position within its respective repeatable geometric pattern, becomes a stimulating electrode and is connected to the appropriate electronic circuit for subsequent, potential use in nerve stimulation.

  • Patent number: 8588930
    Abstract: A method for stimulating a predetermined body part such as a nerve using a stimulation device including an external non-implantable transmitting device powered by a power source and generating an electrical waveform signal. A surface electrode applies the generated electrical waveform signal transcutaneously. An implantable piezoelectric element receives the applied electrical waveform signal generated transcutaneously and, in turn, causes mechanical deformation resulting in mechanical vibration of the implantable piezoelectric element sufficient to stimulate the predetermined body part. The electrical waveform signal may be either a high frequency continuous waveform or high frequency burst packets.
