  • Patent number: 10475634
    Abstract: The vacuum electro-spray ion source comprises a hollow capillary, a vacuum cavity, a gas inlet pipe, a gas supply device and an adjusting device, wherein a first end of the hollow capillary is a sampling port, and a second end is used as a spray nozzle for vacuum electro-sprays and stretches into the vacuum cavity; the air pressure in the vacuum cavity is ranged from 10 to 200 Pa; one end of the gas inlet pipe stretches into the vacuum cavity, and the other end is connected with the gas supply device; and the adjusting device is configured for adjusting the gas inlet pipe to allow the gas to flow therein intermittently. The ion source may achieve electro-spray ionization in the vacuum environment, so that losses during ion transmission may be reduced to improve the signal intensity and detection limit during detection.

  • Publication number: 20190217105
    Abstract: An apparatus comprises a communication channel comprising a plurality of disparate sequential communication links configured to facilitate bi-direction communication between an implantable medical device (IMD) and a programmer. A transceiver is configured to communicate with the programmer via a first communication link of the plurality of disparate communication links. A telemetry device is configured to communicate with the IMD via a second communication link of the plurality of disparate communication links. A third communication link communicatively couples the transceiver and the telemetry device. A power source is coupled to the transceiver and to the telemetry apparatus. An operational status of at least the first and second communication links can be individually determined in real-time.

  • Patent number: 10286206
    Abstract: An electrode cuff includes a first elongate portion and a second elongate portion. The first elongate portion is configured to removably contact a length of a nerve while the second elongate portion extends outwardly at an angle relative to a first side edge of the first elongate portion to at least partially wrap about the nerve. The electrode cuff includes a first series of electrodes that is spaced apart longitudinally along the first elongate portion.

  • Publication number: 20180296829
    Abstract: A system and method for treating sleep apnea includes inserting an implantable pulse generator subcutaneously within a body of a patient and connecting a lead to the pulse generator. The lead is inserted within the vasculature and advanced transvenously through the vasculature until a stimulation portion of the lead becomes positioned in close proximity to the hypoglossal nerve. A nerve-stimulation signal is applied to the hypoglossal nerve via the stimulation portion of the lead.

  • Publication number: 20180220921
    Abstract: A system and method for identifying a stimulation location on a nerve is disclosed. The system includes an image-based navigation interface used to facilitate advancing a stimulation element within a patient body toward a target nerve stimulation site. Using the system one determines, separately for each potential target nerve stimulation site, a neuromuscular response of muscles produced upon applying a stimulation signal at the respective separate potential target stimulation sites. The image-based navigation interface is configured to display a graphic identification of which muscles were activated for each respective potential target nerve stimulation site upon applying the stimulation signal.

  • Publication number: 20180161583
    Abstract: A programmer is configured to effect communication with, and programming of, an implantable medical device configured to deliver neurostimulation therapy. The programmer comprises a display, such as touch screen display, and a processor comprising memory and coupled to the display. An interface is coupled to the processor and configured to receive therapy settings data indicative of current therapy settings operative in the implantable medical device and any modifications made to the therapy settings by a patient. The processor is configured to determine if one or more therapy settings have been modified since the last interaction with the patient, and coordinate displaying of the current therapy settings, the one or more therapy settings modified by the patient, and a previous state of the one or more therapy settings modified by the patient on the display.

  • Publication number: 20180110988
    Abstract: According to various method embodiments, a person is indicated for a therapy to treat a cardiovascular disease, and the therapy is delivered to the person to treat the cardiovascular disease. Delivering the therapy includes delivering a vagal stimulation therapy (VST) to a vagus nerve of the person at a therapeutically-effective intensity for the cardiovascular disease that is below an upper boundary at which upper boundary the VST would lower an intrinsic heart rate during the VST.
