  • Patent number: 9707396
    Abstract: Techniques, devices, and systems may include screening effective therapies using cortical evoked potentials. In one example, a system may be configured to receive a first sensed cortical evoked potential of a patient that occurred in response to an induced sensation at an anatomical region different from a brain region of the patient and receive a second sensed cortical evoked potential that occurred in response to electrical stimulation delivered to one or more nerves associated with the anatomical region. The electrical stimulation may be at least partially defined by a set of therapy parameter values. The system may also compare a first value of a characteristic of the first sensed cortical evoked potential to a second value of the characteristic of the second sensed cortical evoked potential and determine, based on the comparison, efficacy of a therapy configured to treat a condition associated with the anatomical region.

  • Patent number: 9669216
    Abstract: Disclosed are methods for regulating neurotrophin levels within a human body. The invention utilizes an implantable signal generator to deliver stimulation to neural tissue elements. Alternatively, an implantable pump may be utilized to delivery one or more drugs. The implanted device delivers treatment therapy to the neural tissue to thereby alter the level of neurotrophic factors such as BDNF expressed by the influenced neural tissue. A sensor may be used to detect various symptoms of a nervous system disorder. A microprocessor algorithm may then analyze the output from the sensor to regulate the treatment therapy delivered to the body. The invention describes a novel method to regulate the intrinsic levels of neurotrophins and may be used to treat patients with neurological and cognitive disorders.

  • Patent number: 9662022
    Abstract: What is disclosed is a system and method for extracting photoplethysmographic (PPG) signal (i.e., a cardiac signal) on a continuous basis from a time-series signals obtained from video images captured of a subject being monitored for cardiac function in a non-contact remote sensing environment involves the following. First, a time-series signal obtained from video images captured of a region of exposed skin where a photoplethysmographic (PPG) signal of a subject of interest can be registered. A sliding window is then used to define consecutive sequential segments of the time-series signal for processing. Each of the consecutive time-series signal segments is detrended such that low frequency variations and non-stationary components are removed. The detrended signals are processed to obtain, for each segment, a PPG signal. The PPG signal segments are then stitched together using a stitching method, as disclosed herein, to obtain a continuous PPG signal for the subject.

  • Patent number: 9597495
    Abstract: The invention is a method of identifying a preferred location for an electrode array to the neural characteristics of an individual subject. The response to electrical neural stimulation varies from subject to subject and array location to array location. Measure of impedance may be used to predict the electrode height from the neural tissue and, thereby, predict the preferred location. Alternatively, electrode height may be measured directly to predict the preferred location.

  • Patent number: 9585718
    Abstract: In order to reliably cut off a living tissue by using a microwave in a surgical operation without causing excessive damage to the living tissue or without bleeding, it is necessary to suppress energy attenuation until the microwave reaches electrode blades for nipping, coagulating, and cutting off a tissue. However, it is difficult to suppress the energy attenuation. The present invention relates to a medical treatment device capable of reliably cutting off a living tissue by using a microwave while sealing vasculature by coagulating the living tissue without excessively damaging the living tissue. Specifically, the present invention relates to a medical treatment device including a movable first electrode blade connected to an external conductor and a fixed second electrode blade connected directly to a central electrode.
