  • Patent number: 10668272
    Abstract: A cochlear implant of a cochlear implant system is described. The cochlear implant comprises electrodes which are mechanically connected to one another and can be inserted in a row in the form of a spiral into a cochlea in order for auditory nerve receptors to be stimulated, a control circuit that can specifically apply electric pulses to the individual electrodes, and an energy source. The control circuit allows the electrodes to be fed in a pulsed manner with electric signals generated by a processor from the acoustic signals, and auditory nerve receptors adjacent to the electrodes to be stimulated. The electrodes are components of modules, each of which comprises its own decoder-and-control circuit for decoding module addresses and stimulation signals and generating electric pulses for the electrodes. Encoded module addresses and stimulation signals generated from acoustic signals are applied to inputs of the decoder-and-control circuit.

  • Patent number: 10661081
    Abstract: A non-invasive method and device for treating gastroesophageal reflux disease (GERD) in a patient are disclosed. The method calls for positioning electrodes, and applying electrical symmetrical bursts. In particular, positioning step requires positioning a plurality of electrodes in electrical contact with the skin of a target region of the abdomen of the patient. The application step calls for applying a series of electrical symmetrical bursts to said electrodes. That application step generates contractions of abdominal muscles thereby generating movements of a digestive system of said patient wherein said movements are for causing the content of the esophagus to return to the stomach and to relieve GERD symptoms of said patient.

  • Patent number: 10632239
    Abstract: A centrifugal blood pump uses the “double suction” arrangement of the blood flow channels, by dividing the blood flow across the impeller into two practically identical streams, one flowing across the upstream side of the impeller and the other flowing across the downstream side. The double suction arrangement is obtained by using a “flow through cone bearing” mounted to the hub of the impeller. The impeller is attached to the driving motor by three posts, which do not significantly diminish the flow area. The annular flow through the motor “air gap” reaches the flow channel as a single stream and divides into two streams in the vicinity of the posts. The flow is distributed equally to the two sides of the impeller. After passing across the impeller the two streams combine into one that enters the spiral volute and continues past the pump cutwater and through the outflow channel.

  • Patent number: 10589109
    Abstract: A wearable cardioverter defibrillator system includes a support structure that is configured to be worn by a patient. When thus worn, the support structure may attach electrodes at different locations of the patient's body, so as to define different vectors. A measurement circuit may sense ECG signals from the different vectors substantially concurrently. A processor may multiply together these substantially concurrent ECG signals to derive a product waveform. The processor may then detect peaks in the product waveform, measure durations of time intervals between successive peaks, and determine the patient's heart rate from these durations. An advantage can be that the heart rate may be computed notwithstanding noise in the individual ECG signals.

  • Patent number: 10582866
    Abstract: Computer implemented methods, devices and systems for monitoring a trend in heart failure (HF) progression are provided. The method comprises sensing left ventricular (LV) activation events at multiple LV sensing sites along a multi-electrode LV lead. The activation events are generated in response to an intrinsic or paced ventricular event. The method implements program instructions on one or more processors for automatically determining a conduction pattern (CP) across the LV sensing sites based on the LV activation events, identifying morphologies (MP) for cardiac signals associated with the LV activation events and repeating the sensing, determining and identifying operations, at select intervals, to build a CP collection and an MP collection. The method calculates an HF trend based on the CP collection and MP collection and classifies a patient condition based on the HF trend to form an HF assessment.

  • Patent number: 10575747
    Abstract: A system for the assessment and monitoring of the fetal electrocardiogram (ECG) and heart rate in a pregnant mother comprises wearable mechanical-electronic sensors, e.g., embedded in a wrist or arm band, which can measure the mechanical pulse signals from the mother, and an abdomen patch which can measure the combined ECG signals of the fetus and mother. The wrist or arm unit and the abdominal patch unit communicate wirelessly. By signal processing and gating out the maternal ECG signals as correlated with the mechanical maternal pulse signals, the fetal ECG and heart rate can be measured and monitored. These measurements may be displayed on the wrist or arm band device, or wirelessly through a remote device, mobile phone or computer. Electronic-mechanical sensors can also be embedded in the abdominal patch to measure uterine electromyogram (EMG), uterine contractions and fetal movements, to be correlated with the fetal ECG.
