Abstract: A system is provided herein for stimulating an anatomical element of a patient. For example, the system may include a device (e.g., an implantable pulse generator) and an electrode device electrically coupled to the device. In some examples, the device may be configured to generate a current that is to be applied to the anatomical element via the electrode device to stimulate the anatomical element as part of a therapy aimed at achieving or supporting glycemic control in the patient. Additionally, the current may be applied to the anatomical element based on a machine learning algorithm that uses inputs gathered for determining one or more characteristics for the current. Accordingly, the machine learning algorithm may be configured to determine the one or more characteristics for the current specific to the patient (e.g., to provide personalized therapy settings for the patient).

Abstract: A system is described that includes: a first sensor that measures a glycemic level of a patient; a second sensor that measures at least one of a protein level of the patient, a hormone level of the patient, and an activity level of the patient; a processor that receives inputs from the first sensor and inputs from the second sensor; and memory including data that, when executed by the processor, enables the processor to perform one or more functions. An example of such function(s) include: analyzing the inputs received from the first sensor and the second sensor; determining, based on the analysis, that an electrical treatment is to be applied to the patient, where the electrical treatment includes application of at least one electrical signal to a nervous system of the patient; and causing the electrical treatment to be applied to the nervous system of the patient.

Abstract: A system is provided herein for stimulating an anatomical element of a patient to regulate insulin production of the patient. In some examples, the system may include a device configured to generate a current and an electrode device electrically coupled to the device. Subsequently, the device may receive instructions to apply the current to the anatomical element via a plurality of electrodes of the electrode device, where the current is configured to regulate insulin production of the patient. For example, a first electrode may be configured for placement on or around a celiac vagal trunk, where the current downregulates neural activity of the celiac vagal trunk, and a second electrode may be configured for placement on or around a hepatic vagal trunk, where the current upregulates neural activity of the hepatic vagal trunk.

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.

Abstract: An in-ear device occludes an ear canal of an ear of a user. The in-ear device is configured to be calibrated such that the user perceives audio content as though the in-ear device is not occluding the ear canal. A transducer of the in-ear device presents audio content, and an inner microphone of the in-ear device detects sound pressure data within the ear canal. A controller of the in-ear device determines a blocked sound pressure at the entrance to the ear canal based on sound pressure data from an outer microphone. The controller generates sound filters custom to the user based in part on the detected sound pressure within the ear canal and the blocked sound pressure at the entrance to the ear canal. The controller adjusts audio content using the sound filter, and the transducer presents the adjusted audio content to the user.
