  • Publication number: 20230355981
    Abstract: A system is provided herein for stimulating an anatomical element of a patient. For example, a device may be configured to generate a current, and an electrode device coupled to the device may be configured to apply the current to the anatomical element. In some examples, the current may be configured to prevent hypoglycemic episodes from occurring in the patient when applied to the anatomical element. For example, the current may be configured to downregulate neural activity of a celiac vagal trunk and to upregulate neural activity of a hepatic vagal trunk. Accordingly, the current being applied to anatomical element of the patient may result in a decrease in insulin production of the patient, an increase in glucose production of the patient, an increase in blood sugar levels of the patient, or a combination thereof. Additionally, applying the current may prevent nocturnal hypoglycemic episodes from occurring.

  • Patent number: 11771903
    Abstract: An apparatus external to a patient and communicatively coupled to an implant within the patient is disclosed. The apparatus identifies a tentative stimulation parameter adjustment constraint and an absolute stimulation parameter adjustment constraint for a stimulation parameter associated with the implant. The apparatus also determines an impedance of an electrode implanted within the patient and coupled with the implant. Based on the impedance of the electrode, the apparatus automatically adjusts the stimulation parameter within a range between a present value and a first value defined by the tentative stimulation parameter adjustment constraint. Additionally, based on user input manually provided by the patient, the apparatus further adjusts the stimulation parameter within a range between the first value and a second value beyond the first value and defined by the absolute stimulation parameter adjustment constraint.

  • Publication number: 20230233857
    Abstract: An illustrative scalar translocation detection system directs a loudspeaker to apply acoustic stimulation to a cochlear implant patient while an electrode lead is inserted into a cochlea of the cochlear implant patient. The system detects a first evoked response to the acoustic stimulation while an electrode is positioned at a first location in the cochlea and detects a second evoked response to the acoustic stimulation while the electrode is positioned at a second location in the cochlea. Then, based on at least one of an amplitude change or a phase change between the first and second evoked responses, the system determines that a scalar translocation of the electrode lead from one scala of the cochlea to another scala of the cochlea has occurred. Based on this determination, the system also notifies a user that the scalar translocation has occurred. Corresponding methods and systems are also disclosed.

  • Patent number: 11642525
    Abstract: An exemplary scalar translocation detection system detects a first evoked response occurring in response to acoustic stimulation applied to a cochlear implant patient. The system detects the first evoked response by way of an electrode configuration disposed on an electrode lead while the electrode configuration is positioned at a first location along an insertion path of the electrode lead into a cochlea of the patient. The system further detects, by way of the electrode configuration while it is positioned at a second location along the insertion path, a second evoked response occurring in response to additional acoustic stimulation applied to the patient. The system further determines an amplitude change and/or a phase change between the first and second evoked responses, and then determines whether a scalar translocation of the electrode lead from one scala of the cochlea to another has occurred based on the amplitude change and/or the phase change.

  • Publication number: 20220355100
    Abstract: An illustrative electrode locating system directs a first electrode on an electrode lead to generate an electrical pulse after being inserted into a cochlea of a patient during an insertion procedure to insert the electrode lead into the cochlea. The electrode locating system then directs a voltage to be detected between a second electrode of the electrode lead that has not yet been inserted into the cochlea and a ground contact that is to remain external to the cochlea after the insertion procedure. Based on the voltage detected between the second electrode and the ground contact, the electrode locating system determines that the second electrode has not yet been inserted into the cochlea. Corresponding systems and methods are also disclosed.
