摘要： Articles and systems configured for treating GI motility disorders are generally provided. In some embodiments, an article comprising one or more electrodes (with both sensing and stimulating capabilities) may be configured to stimulate one or more tissues in the GI tract, electrically and/or chemically, to modulate peristalsis and/or allow neuromodulation. In some embodiments, a system comprises a controller that allows for close-loop operation of the article, e.g., such that the article may stimulate (e.g., via a feedback loop) the one or more organs in the GI tract upon receiving sensed parameters in the GI tract. In some embodiments, an implantation tool comprising a sensor may allow for submucosal or intramuscular implantation of an article. The implantation tool and the article may be useful for, for example, as a general platform for delivery of treating GI motility disorders and/or neuromodulation of the GI tract.

摘要： Self-righting articles, such as self-righting capsules for administration to a subject, are generally provided. In some embodiments, the self-righting article may be configured such that the article may orient itself relative to a surface (e.g., a surface of a tissue of a subject). The self-righting articles described herein may comprise one or more tissue engaging surfaces configured to engage (e.g., interface with, inject into, anchor) with a surface (e.g., a surface of a tissue of a subject). In some embodiments, the self-righting article may have a particular shape and/or distribution of density (or mass) which, for example, enables the self-righting behavior of the article. In some embodiments, the self-righting article may comprise a tissue interfacing component and/or a pharmaceutical agent (e.g., for delivery of the active pharmaceutical agent to a location internal of the subject). In some cases, upon contact of the tissue with the tissue engaging surface of the article, the self-righting article may be configured to release one or more tissue interfacing components. In some cases, the tissue interfacing component is associated with a self-actuating component. For example, the self-righting article may comprise a self-actuating component configured, upon exposure to a fluid, to release the tissue interfacing component from the self-righting article. In some cases, the tissue interfacing component may comprise and/or be associated with the pharmaceutical agent (e.g., for delivery to a location internal to a subject).

摘要： Components with relatively high loading of active pharmaceutical ingredients (e.g., drugs), are generally provided. In some embodiments, the component (e.g., a tissue interfacing component) comprises a solid therapeutic agent (e.g., a solid API) and a supporting material (e.g., a binder such as a polymer) such that the solid therapeutic agent is present in the component in an amount of greater than or equal to 10 wt % versus the total weight of the tissue interfacing component. Such tissue-interfacing components may be useful for delivery of API doses e.g., to a subject. Advantageously, in some embodiments, the reduction of volume required to deliver the required API dose as compared to a liquid formulation permits the creation of solid needle delivery systems for a wide variety of drugs in a variety of places/tissues (e.g., tongue, GI mucosal tissue, skin) and/or reduces and/or eliminates the application of an external force in order to inject a drug solution through the small opening in the needle. In some cases, a physiologically relevant dose may be present in a single tissue interfacing component (e.g., having a relatively high API loading).
